Bioenergetics, Trophic Dynamics & Nutrition

2. the process by which consumers (like animals) convert primary producers into energy.
5. the loss of hydrogen
8. When energy is lost as it moves from one trophic level to another
10. Any organism that consumes or feeds largely on primary consumers
12. an animal that obtains its nutrition by eating primary consumers and secondary consumers.
13. show how all the food chains in an ecosystem interact.
15. organisms that break down dead organisms and release the nutrients from the dead matter into the environment around them.
17. an organism's position in the food pyramid
19. an organism that can produce its own food using light, water, carbon dioxide, or other chemicals.
21. the process of absorbing nutrients during digestion and distributing them to cells for growth and repair.
22. a linear sequence of organisms through which nutrients and energy pass as one organism eats another.
23. model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem.

1. the synthesis of organic compounds from atmospheric or aqueous carbon dioxide.
3. an organism that feeds on primary producers
4. a system that permits the inflow and outflow of energies only
6. autotrophic organisms that can rely on chemosynthesis
7. an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon
9. organisms that can produce organic matter using an external energy source.
11. a measure of the total mass of living material in each trophic level.
14. a system that permits the inflow and outflow of information, materials, and energies
16. the process that cells use to make useable energy in the form of ATP
18. The production of an organic compound in a living thing
20. organisms, such as most microalgae, that capture light energy and incorporate carbon dioxide (CO2) to produce organic compounds.
