Energy and Matter

2. the mass of matter produced by an organism in an ecosystem
5. an organism that makes its own food; a producer
7. a green pigment in chloroplasts that captures light energy to make sugars during photosynthesis
9. an organism which must eat other organisms for energy
11. the amount of matter in something
12. the process by which organisms convert sugar into usable energy using oxygen as a reactant
15. an organism that cannot make its own food; must eat other organisms for energy
16. radiant energy that heats
17. the movement of water up through the roots and out of the leaves of a plant
19. the process by which water changes from a vapor to a liquid due to decreased particle motion (loss of heat)

1. the organelle where cellular respiration takes place
3. food in the form of sugar or starch
4. an organism that consumes parts of dead organisms and converts all the biomes into simple chemicals
6. an organelle found in plant cells in which photosynthesis takes place
8. an organism that is able to make its own food; usually through photosynthesis
10. the process by which producers make energy-rich molecules (food) from water and carbon dioxide in the presence of light
13. the process by which water changes from a liquid to a gas or vapor due to increased particle motion (heat)
14. anything that has mass and takes up space
18. the ability to do work
