In the ecological interactions lab activity, each small graduated cylinder (10 mL) represented a small organism. Combining four of these would represent a larger animal consuming four smaller animals. In an ecosystem, the volume of water will decrease as it is used by the animals (evaporation, released with nitrogenous waste). Explain how this will affect the concentration of oil from one trophic level to the next.

h this is kinda confusing

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

the correct answer is sex-linked recessive.

i just took the test
