The fertility of the soil is an important factor in the selection of site for a fish pond because a fertile soil will

  1. encourage the growth of trees within the pond
  2. stimulate growth of lower plants which are sources of food to fish ✓
  3. add minerals to the water for the fishes resistance to diseases
  4. prevent the pond from drying up

Explanation

Fertile soil releases nutrients into pond water. These nutrients feed tiny plants called algae and phytoplankton.

Small fish eat these tiny plants, and bigger fish eat the smaller fish. This food chain starts with nutrients from fertile soil.

Without fertile soil beneath the pond, there would be less natural food for the fish.
