Question

The diagram below shows a food web.

If a certain organism is a producer, what best explains its position in the food web?

B, because organism B utilizes radiant energy from the sun
A, because organism A has the same role as the algae
B, because organism B has the same role as the crabs
A, because organism A utilizes energy from mussels

Answer 1

Neither C nor D (neither describes the a producer). Not A because that information is not given. So Option B: A, because organism A has the same role as the algae. (It also has the same role as the seaweed, which is also a producer.)
