Ecosystem processes

2. Organism that makes its own food using photosynthesis.
3. The process plants use to make their own food, glucose. In photosynthesis, carbon dioxide and water react together to make glucose and oxygen.
5. The build up of toxic chemicals inside organisms in a food chain.
7. Chemical containing minerals, normally applied to soil.
9. Chemical reaction used by microorganisms to convert glucose into ethanol, carbon dioxide, and energy.
11. Holes found on the bottom of the leaf that allow gases to diffuse in and out of the leaf.
12. A particular place or role that an organism has in an ecosystem.

1. Chemical reaction where glucose reacts with oxygen to release energy, carbon dioxide, and water. __________ respiration.
2. The number of plants or animals of the same type that live in the same area.
4. The way in which living organisms depend on each other to survive, grow, and reproduce.
6. Green pigment that absorbs light for use in photosynthesis.
8. Organisms that eat other organisms as food.
10. Chemical reaction that takes place without oxygen. Glucose is converted into lactic acid and energy is released. __________ respiration.
