Question

why do trees fluctuate with wolf-moose, predator-prey population cycles?
a they are a predator food source.
b they are a prey food source.
c they are dependent on predators.
d they are dependent on decomposers.
e they grow best when the ends of branches are eaten.
question 8
ocean fish that swim in schools demonstrate which distribution pattern?
a random
b uniform
c clumped
d irregular

Explanation:

For the first question: Moose (prey) feed on trees. When moose populations rise, tree consumption increases (trees decline); when wolves (predators) reduce moose populations, tree growth recovers. Thus trees fluctuate as a prey food source.
For the second question: Schooling fish gather in groups for protection or resource access, which is a clumped distribution pattern.

Answer:

First question: B. They are a prey food source.
Second question: C. clumped
