In an ecological interaction between two species of wild plants (X1 and X2) and a crop plant ( Y ), wild plants compete with crop plants for nutrients. There is a group of plant pests ( P ) that infect crop plants and damage them. Further, wild plants X1 support the population of insects (T1) that feast on the plant pest ( P ). Wild plants X2 support the dwelling of pollinator insects (T2) that promote pollination in

Options

  1. AThere is direct negative interaction of Y with X 1 and X 2 .
  2. BThe interaction between T1 and T2 insects is commensalism.
  3. CRemoving wild plants X1 and X2 from this ecosystem will improve overall crop ( Y ) productivity.
  4. DThe interaction between T 1 and crop plants Y is parasitism.

Correct answer

A. There is direct negative interaction of Y with X 1 and X 2 .
