Ecological Concept Example A.Upright Pyramid of Energy 1. Biomass of fishes exceeds that of phytoplankton B. Inverted Pyramid of Biomass 2. Energy is lost as heat at each trophic level C. Trophic Level Representation 3. A single species can occupy multiple levels D. Pyramid of Numbers in Forest 4. A large tree supports many insects

Options

  1. AA - 2, B - 1, C - 3, D - 4
  2. BA - 2, B - 1, C - 4, D - 3
  3. CA - 4, B - 3, C - 2, D - 1
  4. DA - 3, B - 4, C - 1, D - 2

Correct answer

A. A - 2, B - 1, C - 3, D - 4

Step-by-step solution

Inverted Pyramid of Biomass (B) is seen in aquatic ecosystems where biomass of fishes exceeds that of phytoplankton (1). Upright Pyramid of Energy (A) is due to energy loss as heat at each step (2), making it always upright. Trophic Level Representation (C) highlights that a single species can occupy multiple levels (3), such as a sparrow being both a primary and secondary consumer. Pyramid of Numbers in Forest (D) could be upright or spindle-shaped, as a large tree can support many insects (4), leading to a potent
