Term Description A. Detritus Food Chain (DFC) 1. Food chain starting with primary producers B. Grazing Food Chain (GFC) 2. Connected with the DFC at some levels C. Saprotrophs 3. Decomposers breaking down dead organic matter D. Trophic Level 4. Organism's position in a food chain

Options

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

Correct answer

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

Step-by-step solution

Detritus Food Chain (DFC) (A) is connected with the GFC at some levels (2) because some detritivores are prey to grazing food chain animals. Grazing Food Chain (GFC) (B) starts with primary producers (1) and moves up through herbivores and carnivores. Saprotrophs (C) are decomposers breaking down dead organic matter (3). Trophic Level (D) refers to an organism's position in a food chain (4).
