Ecosystems
| Question | Answer |
|---|---|
| Biotic Factors | a living thing, as an animal or plant, that influences or affects an ecosystem. |
| Abiotic Factors | a nonliving condition or thing, such as climate or habitat, that influences or affects an ecosystem and the organisms in it. |
| Ecosystem | All living and nonliving things in an area that interact |
| Habitat | The environment where an organism lives |
| Organism | One individual plant, animal or bacteria(a living thing) |
| Population | All of one type of organism in an area |
| Community | All of the population in one area |
| Biosphere | The part of the earth that contains all the ecosystems |
| Producer | Living things that can make their own energy out of non-living resources like light and water |
| Consumer | Living beings that need to eat other organisms to survive |
| Decomposer | Living things that get their nutrients from other organisms or from waste matter expelled by other organisms. Usually they eat dead animals and plants. |
| Herbivore | An animal that gets their energy by only eating producers or plants |
| Carnivore | An animal that gets their energy by only eating other consumers |
| Omnivore | An animals that gets their energy by eating both producers and consumers |
| Scavenger | A consumer that eats dead animals |
| Predator | Any organism that exists by preying on other organisms |
| Prey | An animal hunted or seized for food |
| Niche | The role or job that an organism plays in a habitat |
| Deciduous Forest | Have trees that lose their leaves and some evergreens. They also have mild temperatures. |
| Grassland | Has a lot of flat, wide open space with a lot of grass |
| Rainforest | Home to millions of plants and animals. It also has a very tropical climate |
| Desert | Usually very hot with very little precipitation. |
| Aquatic Ecosystem | Water-based ecosystem |
| Terrestrial Ecosystem | Land-based ecosystem |
| Freshwater | Water that doesn't have much salt |
| Pond | A freshwater ecosystem. The smallest body of water. It’s surrounded by land on all sides and the water does not flow. |
| Lake | Can be natural or man made. It’s surrounded by land on all sides and the water does not flow. It’s bigger than a pond. |
| River/Stream | Freshwater ecosystems that flow downhill and toward the ocean. |
| Saltwater ecosystem | Very salty water-based ecosystem |
| Ocean | The largest body of water on earth. It has waves and currents. |
| Saltmarsh | Also known as a ‘flooded grassland’. It’s found near the coast. |
| Estuary | Located where rivers and oceans meet. It contains a mix of freshwater and saltwater |
| Biome | A community of plants and animals on a large scale and include multiple ecosystems |
| Food Chains | Paths energy takes from producers to consumers to decomposer |
| Primary consumer | An organism that eats plants and provides the energy needed for other types of consumers to use |
| Secondary consumer | Organisms that prey upon primary consumers |
| Tertiary consumer | Animals that consume other animals to obtain nutrition from them |
| Trophic levels | Producer to primate consumer to secondary consumer to tertiary consumer to quaternary consumer to decomposer |
| Autotroph | Organisms that can make their own food from abiotic natural resources |
| Heterotroph | an organism that eats other organisms for nutrients |
| Brackish | slightly salty |
| Competition | the direct or indirect interaction of organisms that leads to a change in fitness when the organisms share the same resource |
| Food webs | a group of food chains within an ecosystem |
| Energy pyramid | a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem |
| Natural Resources | resources that are found in nature and can be used by people |
