Question

1. what is one major difference between food webs and food chains?

a. food webs cross into more than one environment.
b. food webs show multiple connections among organisms.
c. food webs trace the source of energy all the way back to the sun.
d. food webs contain multiple consumers using a single energy source.
which of the following would most likely happen if all of the mice were removed from this ecosystem?
a. the wolf population would decrease.
b. the rabbit population would decrease.
c. the deer population would increase.
d. the toad population would increase.

1. this diagram shows a food web for a forest ecosystem. the shows what each the transfer of energy between each of the trophic levels and shows type of organism eats.

Explanation:

1. In a food web, if mice (a food source for wolf) are removed, the wolf population would decrease as they have less food.
2. Food webs cross into more than one environment (e.g., terrestrial and aquatic elements in some webs), show multiple connections among organisms (unlike simple food chains), trace the source of energy back to the Sun (like food chains), and contain multiple consumers using a single energy source (but the key difference is crossing environments).

Answer:

1. A. The wolf population would decrease.
2. A. Food webs cross into more than one environment.
