Question

* Marine science *
There is a correlation between algae height and the snout-to-vent length of a group of marine iguanas in the Galapagos; as algae height increases for a given island, so does iguana length. Why would the body size of this population of iguanas correlate with algae height?

Differential reproduction of larger animals is favored when adequate nutrition is supplied by larger algae.
Increased variation in animal size is favored when large plant species are present in a healthy ecosystem.
Overproduction of smaller animals is favored when algae swards are short and vice versa wh

Answer 1

A)Differential reproduction of larger animals is favored when adequate nutrition is supplied by larger algae.

B) Increased variation in animal size is favored when large plant species are present in a healthy ecosystem.

C)Overproduction of smaller animals is favored when algae swards are short and vice versa when algae swards are long

D) Traits are exchanged between iguana and algae populations so that taller algae result in larger iguana populations.

Answer 4

Okay, so think of it this way:

If you feed one fish smaller pieces of fish food and you feed another fish larger pieces of fish food, which fish will get bigger, and why?

Answer 5

the one who is consuming more

Answer 6

The one that's bigger.

Answer 7

That's right.

So, since there is a larger amount of food that can be consumed, the organism(s) that are consuming the food are also going to increase in size.

So now, with more larger organisms, there will be more reproduction between larger organisms, which will in turn result in an increased number of larger organisms (hopefully that makes sense). This is part of Darwin's theory of Natural Selection.

With that said, have you found your answer?
