Wolves prey heavily on beavers in a temperate forest ecosystem. The diet of beavers consists of the leaves, branches and bark from trees, as well as many types of aquatic vegetation. In this relationship, what is the role of the wolves? A producer B decomposer C primary consumer D secondary consumer

In this relationship , the role of wolves is  as Secondary Consumers .

Explanation:

A PRODUCER - Producers are referred to as an organism that prepares its own food. Often, they are called autotrophs.  

A DECOMPOSER -: Decomposers are organisms which break down organisms and waste that are dead or decaying. Their function is ecologically important as they recycle the nutrients through a natural biological process (decomposition).

PRIMARY CONSUMERS -: Typically, primary consumers are herbivores-animals that eat plants. Since they have to eat other items to survive, they are called heterotrophs. This is different from farmers who make their own food and are autotrophic.

SECONDARY CONSUMERS -: The secondary consumers are species that eat energy from the primary consumers. Only other animals eat carnivores, and omnivores both eat plant and animal matter.  

In the given foodchain , the wolves are consuming beavers as their food and beavers consume leaves , branches and twigs as their food. Therefore , it is cleared from the above definations , that leaves and branches consumed by the beaver are  producers(as they are the part of plants ) , the beavers are herbivores dependent on green plants , so they are primary consumers and the wolves who are preying on beavers are secondary consumers as they are carnivores .

Hence, the correct answer is  OPTION D.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
