Which of the following statements best describes the response of finches to drought on the galapagos islands?
a. during drought, individual finches saw that large, hard seeds were the only available food. to crack these harder seeds, individual finches grew their beaks larger, resulting in an increased average beak depth.

b. during drought, finches struggled to open harder seeds. all the scraping and pecking wore down their beaks, resulting in a reduced average beak depth.

c. during drought, only finches with larger-than-average beaks were able to crack the hard seeds that were available. these finches survived while smaller-beaked finches died, resulting in an increased average beak depth in the population.

d. during drought, finches with smaller beaks (and smaller bodies) had an advantage. with reduced food supplies, larger finches (with larger beaks) were more likely to starve. the result was a decrease in average beak depth.

C. During drought, only finches with larger-than-average beaks were able to crack the hard seeds that were available. These finches survived while smaller-beaked finches died, resulting in an increased average beak depth in the population.

Explanation:

Variations were present in the gene pool of sexually reproducing population. The finch population had both finches with larger-than-average beaks and the one with shorter beaks. The beneficial variations such as presence of larger-than-average beaks imparted survival and reproductive advantage to these finches. These finches were able to feed themselves, reproduced and pass the trait to the offspring.

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)
