Using the sections of the pyramid provided, which answer choice describes a relationship found in an ecosystem?
A.
II represents secondary consumer and III represents a tertiary consumer, which explains why the top of the pyramid is smaller than the base.
B.
IV represents producers and I represents primary consumers which explains why the base of the pyramid is the largest.
C.
IV represents the top predator and I represents the primary producers, which explains why the base of the pyramid is larger than the top.
D.
I represents a predator and II represents a prey which explains why the top of the pyramid is smaller than the base.
Name the trophic levels in an ecosystem and explain how energy moves through the trophic levels. Can you use the words food chain and food web in the discussion.
