Leya [2.2K]

Complete question:

Which organisms are secondary consumers in a temperate coniferous forest? Select all that apply:

  • moose
  • lynx
  • wolf
  • elk

Answer:

The lynx and the wolf are the only secondary consumers on the list.

The first ones are the autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter.

The following links are the consumers: herbivores are primary consumers and feed on producers. <u>Carnivores are secondary consumers and feed on herbivores</u>, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.

According to the definition of secondary consumers, among the animals on the list, we can assume that the lynx and the wolf are the only secondary consumers. They are both carnivores and feed on herbivores.

On the other hand, the moose and the elk, are both first consumers.
