Producers provide energy for other organisms in an ecosystem.0165735autotrophseatingnonliving abioticlivingtemperatureproducersmoistureplantsanimalsbioticconsumersheterotrophsnonliving00autotrophseatingnonliving abioticlivingtemperatureproducersmoistureplantsanimalsbioticconsumersheterotrophsnonlivingComplete the following sentences with the correct term from the list below6. All ecosystems are made up of living and nonliving components.7. Biotic factors are living things, such as plants or animals.8. Abiotic factors are nonliving things, such as wind, Temperature, or moisture.9. Autotrophs are organisms that get their energy from nonliving resources, meaning they make their own food. These organisms are also called Producers. 10. Heterotrophs are organisms that get their energy by eating other organisms. These organisms are also called consumers.11. Why are producers so important to an ecosystem? They are the base of the food chain! KEY CONCEPT: Food chains and food webs model the flow of energy in an ecosystem.0147320carnivoreherbivoresecondary consumerdecomposerdetritivoreomnivoreprimary consumertertiary consumertrophic levels00carnivoreherbivoresecondary consumerdecomposerdetritivoreomnivoreprimary consumertertiary consumertrophic levelsChoose the correct term from the box below to fit each description.12.

It includes multiple feeding options. 22. Label the four tiers of the energy pyramid with the correct trophic level (producers, primary consumers, secondary consumers, and tertiary consumers). Choose an ecosystem. Research what types of plants and animals live in your chosen ecosystem. Fill in the energy pyramid with what might exist with that ecosystem.3493770130175006858003619500473202012255510% of Energy is lost at each level. 0010% of Energy is lost at each level. 231457564770Tertiaryconsumer 00Tertiaryconsumer 2362200110490Secondary consumer 00Secondary consumer 205740019050Primary consumer 00Primary consumer 1905000102870Producer00Producer ................
