| Question | Answer |
|---|---|
| all organisms living in a given area withe the abiotic factors with which they interact | ecosystem |
| Place the following in their proper position in a food chain----turtle, algae, fish | algae, fish, turtle |
| these organisms use sunlght as their sources of energy | producers |
| carnivores that eat herbivores | secondary consumers |
| these organisms eat the producers | primary consumers |
| carnivores that eat other carnivores | tertiary consumers |
| example would be a shark eating a seal or a lion eating you | tertiary consumers |
| consumers that derive energy from organic waste and dead organisms | decomposers |
| as one moves from one trophic level to the next, what happens to the available energy | lost as heat |
| a representation used to illustrate the process of eating and being eaten | food chain |
| composed of a number of food chains linked together | food web |
| the rate of generation of biomass | productivity |
| amount of energy trapped in organic matter at a given trophic level minus that lost by respiration of the organisms at that level | net productivity |
| the loss of energy between one trophic level and the next Is | 10 % |
| what happens to the number of individuals as you move from one trophic level to the next | the number decrease |
| what happens to the amount of biomass produced as you move from one trophic level to the next | the number decreases |
| the accumulation of toxic material as one moves from one trophic level | biological amplification |
| which is the most productive ecosystem | open ocean |
| which is the least productive ecosystem | deserts |
| In the nitrogen cycle, which type of bacteria is responsible for converting atmospheric nitrogen to nitrates? | denitrifying bacteria |
| The dead bodies of animal and plants are converted to ammonium by the action of which types of organisms? | bacteria and fungi |
| Nitrogen-fixing bacteria living in plants are found in ________ _________ of legumes | root nodules |
| In which biogeochemical, cycle to we find bacteria playing a major role? | nitrogen cycle |
| What is a major way in which carbon dioxide introduced into the atmosphere? | burning of fossil fuels and forest |
