Ecosystems and Energy Flow

2. organisms that eat dead organisms
5. Factors all nonliving things in an ecosystem
12. organism that makes its own food using
14. law of Thermodynamics when energy is transformed from one form to other, some of the usable energy is lost to the surroundings.
15. the consumers who get their food by breaking down dead organisms
18. Any living thing
21. study of flow of energy
22. a biological community of interacting organisms and their physical environment
23. when a plant uses sunlight to make sugar molecules
24. law of Thermodynamics energy can neither be created nor destroyed by can be transformed from one form to other
25. study of how organisms interact with each other and their surroundings
26. All individuals of one species that occupy a particular geographic area
27. an organism that eats other plants or animals for energy and nutrients
28. all plant life in a specific habitat

1. respiration process of breaking down food to yield energy
3. part of the Earth where living things thrive and live
4. Factors all living things in an ecosystem
6. cycle a process in which nitrogen is cycled between the atmosphere, bacteria, and other organisms
7. web a diagram that shows many feeding relationships that are possible in an ecosystem
8. cycle process by which carbon is cycled between the atmosphere, land, water, and organisms
9. level Each step in the transfer of energy through a food chain or food web in an ecosystem
10. a group of different species that are commonly found together in a location
11. Pyramid a graphical representation of the energy found within the trophic levels of an ecosystem
13. all animal life in a specific habitat
16. fixing bacteria organisms that can fix atmospheric nitrogen into chemical compounds
17. where a group of organisms live
19. an organism that can produce its own food using light, water, carbon dioxide, or other chemicals
20. organisms that get their energy by eating other organisms.
23. cycle the movement of phosphorous from environment to organisms and then back to the environment
28. chain a sequence in which energy is transferred from one organism to the next as each organism eats another organism
