Page 6 LESSON PLAN INTRODUCE (5 minutes) 1. Human life relies on our ecosystems providing the life-sustaining services of providing oxygen, detoxifying our soil and water, providing materials for clothing and shelter and providing our food and the nutrients we require. In an ecosystem, each An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.Ecosystem… An ecosystem is a collection of all the ________ in a given area. A) is a regional grouping of plants, animals, and other biotic factors B) is the total population of a specific kind of plant, animal, or microbe and all members of which do or potentially can interbreed and Community The interaction of all organisms (more than one population) living in an area. Ecosystem, the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space. Introduce the Voyager Story, Exploring Earth’s Ecosystems: Impacts. Start studying Chapter 5 - Life on Earth. Photosynthesis The chemical process where plants make their own food. [2] These biotic and abiotic components are linked together through nutrient cycles and energy flows. Producers convert energy from the environment into carbon bonds, such as those found in the sugar glucose. Biodiversity is the foundation of ecosystem services to which human well-being is intimately linked. This story is an example of both predation and mutualism. Environment Everything that surrounds an organism and influences it. Energy Flow in Ecosystem - Energy moves life. What category describes a species that, while not presently at risk of extinction, could likely be at risk of extinction in the near future? Three levels of diversity work together to create the complexity of life on Earth. An ecosystem includes all the living things (plants, animals and organisms) in a given area, interacting with each other, and with their non-living environments (weather, earth, sun, soil, climate, atmosphere). - Plants, animals, decomposers, fungi, bacteria, algae The above lists are by no means all-inclusive. What can a human population's age pyramid tell you about current and future needs? tertiary consumer Gets energy from secondary consumers (carnivores) It is measured in global hectares. World population projections predict that, although the global birth rate has declined in recent years, the total human population will continue to increase. 3.2 Ecosystem services, particularly food production, timber and fisheries, are important for employment and economic activity.Intensive use of ecosystems often produces the greatest short-term advantage, but excessive and unsustainable use can lead to losses in the long term. A distinctive biome called a(n) ------ is found where a freshwater stream or river merges with the ocean. How many schools to build or to close down. Niche The position of an organism in a community of plants and animals. Screech owls eat blind snakes. marine ecosystem Includes ocean and sea areas; high salt content Aquatic biomes are defined primarily by ________. Oh no! The presence of a blind snake improves the survival of young chicks. Greater numbers of species are now going extinct faster than ever before. Phytoplankton is an example of a(n) ________. These include cleansing the water ecosystem The living and non-living parts of the environment in a specific area. ecosystem The living and non-living parts of the environment in a specific area. light levels in the ----- are too low to support photosynthesis. No feature of Earth is more complex, dynamic, and varied than the layer of living organisms that occupy its surfaces and its seas, and no feature is experiencing more dramatic change at the hands of humans than this extraordinary, singularly unique feature of Earth. deciduous Trees that lose leaves in the autumn/fall _________are elements required for growth and can affect the ability of an ecosystem to sustain life. Germinate The process of a seed beginning to sprout or beginning to grow into a plant. Carnivore A consumer that only eats animals Ecosystem services are all the processes and outputs nature provides us with. Habitat destruction, overharvesting, invasive species, pollution, and climate change. A community in ecology is defined as ________. An ecosystem consists of all of the populations of multiple species living in the same place at the same time. ...when two or more individuals or populations try to use the same limited resource such as food. What is the ecological footprint for an average U.S. citizen? An ecosystem consists of all of the populations of multiple species living in the same place at the same time false Most ecosystems on earth are powered by --- … Biomes are a group of ecosystems sharing the same characteristics and are well adapted to the prevailing abiotic factors. In prairie grasslands, periodic ----- is an important disturbance, allowing for certain plants to be triggered to grow. Oh no! Humans interact with the world around us every day, but some of our actions are more harmful than others. How might the removal of a wetland affect a nearby city? many different species, with one population being overrepresented in the ecosystem … Herbivore A consumer that only eats plants. What are the main causes of biodiversity loss? These systems contrast with freshwater ecosystems, which have a lower salt content. Eutrophication Increased nutrients in an ecosystem (ex: too much fertilizer) Biomes include both the abiotic and biotic factors. A group of ecosystems that have the same climate and similar communities of plants and animals, a group of the same species of organisms living in an area. An ecological footprint is an estimated amount of land and water required to sustain one person. [3] Ecosystems are of any size, but usually they are in particular places. In an ecosystem, the plants , animals , and other organisms rely on each other and on the physical environment – the soil, water, and nutrients, for example. Identify the biotic factor of an ecosystem among the following options. Our ecosystem is maintained by the cycli Amount of moss available to the consumers. freshwater ecosystem Includes streams, rivers, lakes, marshes and swamps; low salt levels Producer An organism that can make its own food through the process of photosynthesis. As our population approaches 7 billion people, the effects of human activities on the ecosystem, including the water, air, land A wolf eats a rabbit that eats grass. It is the transition zone between freshwater and saltwater biomes. The physical place where an organism lives, The position/role of an organism in a community, An abiotic factor that describes overall weather in an area over a long period of time, a system formed by the interaction of a community of organisms with their physical (abiotic) environment, part of Earth in which life exists including land, water, and air or atmosphere. These include provisioning services (food, water), regulating services (waste water treatment, pollution control), supporting services (shelter), and cultural services (recreation and tourism). food web A system of food chains. primary consumer Gets energy from plants (herbivores) A wolf eats a rabbit that eats grass. All of the following are abiotic factors within an ecosystem except ________. An ecosystem is a natural environment and includes the flora (plants) and fauna (animals) that live and interact within that environment. Learn what biotic and abiotic factors are and how they compose an ecosystem. Terrestrial biomes are defined in a large part by ________. To ensure the best experience, please update your browser. Marine ecosystems are the largest of Earth's aquatic ecosystems and are distinguished by waters that have a high salt content. ...when resources such as food, water or space become limited. How does nitrogen enter the living portion of an ecosystem? the spacing of organism throughout a habitat, A drought in Ethiopia results in the deaths of thousands of wild goats. The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. Abiotic factors are non-living objects, an example would be the air. How does carbon enter the living portion of an ecosystem? There have been several mass extinctions in the planet's history, such as the extinction of the dinosaurs, but the current mass extinction is different. Interdependance The relationship between plants and animals in an ecosystem. Which of the following is not an example of an abiotic factor? Describe energy transfer from the lowest to the highest trophic level in a chain, including energy loss at every trophic level. An ecosystem consists of communities of interacting species and the physical environment on which they depend. It looks like your browser needs an update. Ecosystem Energy: Organisms can be either producers or consumers in terms of energy flow through an ecosystem. ecology The study of how living things are related each other and to their natural environment. Using sunflower plants to naturally remove heavy toxins from contaminated soil is an example of ________. Any earth surface that has got a very large ecological system characterized by dominant forms of plant and animal life forms adapted to the prevailing climate and other environmental factors is termed as a biome. Atmospheric CO2 taken in by photosynthesis. Everything that surrounds an organism and influences it. pollutant Substance with damaging effects on the environment (ex: acid rain, over-fertilization, road salt), a symbiotic relationship in which both species benefit from the association(win/win), any relationship in which two species live closely and interact, occurs when one species benefits from the association while the other is neither helped nor harmed(win/whatever), occurs when one organism lives on or inside another organism and harms it (win/lose). The air you breathe, the water you drink and the food you eat all rely on biodiversity, but right now it is in crisis – because of us. A community includes interacting populations without their surrounding environment, while an ecosystem includes the surrounding environment. terrestrial ecosystem Land areas where microscopic ====== and multicellular algae provide food for the animal community. animals that feed on the bodies of dead organisms. use can lead to … ecosystem 3.FOUR type sof Consumers: H rbiv - anl Carnivores - eat only animals Omnivores - eats plants or animals Scavengers - feed on dead organisms (Crows) 4.T h eGr n ous Effect - Carbon dioxide gas in the and causes Fishes and marine mammals swim in open water known as the. -----can be important in shaping terrestrial ecosystems by allowing animals to cool and even influencing the way plants grow. The buildup of soil on bare rock by the decomposition of early colonizers is characteristic of ________ succession. (Ecosystems can be really small or really large!) But sometimes, a screech owl will bring a live, blind snake back to its nest. Ecology is the field of biology that studies the relationship between living beings Each ecosystem has its own community. Global warming is causing a rise in sea level. Decomposers A consumer that breaks down the tissues of dead organisms as food. First, let's review biotic and abiotic factors. It looks like your browser needs an update. 2) An ecosystem _____. Choose from 500 different sets of what on earth flashcards on Quizlet. The non-living parts of an ecosystem such as soil, climate and rainfall. Biodiversity is usually explored at three levels - genetic diversity, species diversity and ecosystem diversity. The difference would be the factors (biotic or abiotic) which are included in each level of organization. ecology The study of how living things are related each other and to their natural environment. Why is photosynthesis limited to surface water in marine ecosystems? An ecosystem with high species richness but low evenness would have _____.
