Question

more people than usual go fishing and take a lot of the large fish out of the pond. using only the relationships between the plants and animals shown in the diagram, what is likely to happen to the number of insects and why?
a. the number of insects is likely to decrease because with fewer large fish to eat the tadpoles, there would be more tadpoles eating more water plants and fewer water plants available for the insects.
b. the number of insects is likely to decrease because with fewer large fish for the large birds to eat, the large birds would have to eat more insects.
c. the number of insects is not likely to change because large fish are not connected by an arrow in the diagram.
d. the number of insects is not likely to change because people took only large fish out of the pond.

Explanation:

If people take a lot of large fish out of the pond, there will be fewer large - fish to eat water plants. So, there will be more water plants available for insects. With more water plants for insects, the number of insects is not likely to decrease.

Answer:

D. The number of insects is not likely to change because people took only large fish out of the pond.
