Which of the following would most likely have the least amount of biomass and the fewest numbers in a food chain or food web? explain your answer choice.
a. plants b. insects c. spiders d. wolves

The correct answer is d Wolves.

Explanation:

Wolves are placed in the top layer of a food chain or food web because they act as secondary carnivores or tertiary consumers.

  We all know that when an organism of a tropic level eat another another organism that is present to its below tropic level only 10% energy is transferred from n tropic level organism to n+1 tropic lebel organism.

   As Wolves are present in in the 4th tropic level only few percentage of the total biomass of that food chain will be received by them.
