4. Any biotic or abiotic factor that restricts the existence of organisms in a specific environment.
9. Ingesting food containing the suns energy.
10. Anything that eats or consumes other living organisms. All heterotrophs: they ingest food containing the sun’s energy.
13. The concentration of a toxin (like a pesticide) in the tissues of organisms in a lower trophic level gets passed up to the next level when they get eaten.
14. A Non-native organism that brings harm to the environment.
16. All autotrophs that trap energy from the sun/beginning of the food chain.
17. Producer or plant also known as the beginning of a food chain.
18. All living organisms inhabiting the world
19. The scientific study of interactions between organisms and their environments, focusing on energy transfer.

1. Each link in a food chain/Represents a feeding step in the transfer of energy and matter in a ecosystem.
2. The total diversity of organisms. More different organisms=healthier the environment
3. Anything that was alive and is now in or on the soil and must be decomposed into humus.
5. Type of consumer that eats dead plants, animals and other organisms.
6. A substance used for destroying insects or other organisms.
7. Anything that absorbs more carbon from the atmosphere than it releases.
8. Microscopic plants that float among the other plankton in the upper layer of the oceans.
11. The process of burning something
12. A place where an organism stays its whole life.
15. The role a species plays in a community.
17. Nonliving parts of the environment.(i.e. temperature, soil, light, moisture, air currents)
