The formation of fossil fuels in the carbon cycle serves to: o a. keep populations of plants under control. o b. store excess carbon underground. o c. build up the amount of carbon dioxide in the air. dd. preserve organisms that are extinct.

B. store excess carbon underground

Explanation:

The fossil fuels have been formed on the basis of organisms that have died, mostly producers. These organisms have carbon stored in them. As they died and got covered by sediments, the carbon has been stored in the lithosphere. Since more and more sediments have been covering the stored carbon, it has been isolated and stored into the lithosphere for tens or even hundreds of millions of years, thus contributing to lowering the amount of carbon in the atmosphere for quite some time, and removing it from its natural cycle.

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)
