Question 34

Feeding Relationships and Energy Flow

In typical predator food chain involving secondary and tertiary consumers, the organisms become progressively

  1. A.smaller and more numerous along the food chain
  2. B.equal in number and size along the food chain
  3. C.larger and fewer along the food chain
  4. D.parasitized along the food chain as consumers get bigger
Show the answer and explanation

Answer: C (larger and fewer along the food chain)

Explanation

In a predator chain each predator is usually bigger than its prey, and because energy is lost at each level there are fewer of them.
