Non living parts of an ecosystem Precipitation (Rainfall) and temperature Populations of different species that live together in the same area The study of relationships between organisms in an ecosystem. The entire portion of Earth that is inhabited by life All of the organisms in a given area as well as the abiotic factors with which they interact g. An environment that is characterized by specific biotic and abiotic factors—typically climate and a specific type of plant/animal community h. The variety of organisms that live within the biosphere. Energy Flow in an Ecosystem 9. How does energy flow through an ecosystem? 10.What does an energy pyramid tell you 11.What are trophic levels? 12.What happens to energy as it is transferred from one tropic level to the next? D B C A a) Lost to the environment as heat. 10% moves on each trophic level b) The amount of energy that each consumer gains as it eats in a food chain. c) A step in the food chain or food web d) One way from the sun, to autotrophs, to consumers, to decomposers Population Ecology 13. 14. 15. 16. 17. 18. 19.
