please select the best answer from the choices provided

Explanation:

In a food chain, each organism depends on the one before it for food. Garden plants are the producers (the base of the food chain). Snails eat garden plants. If the garden (source of food for snails) is removed, snails will have no food. So, the number of snails will decrease. Birds eat snails. With fewer snails (their food source), the number of birds will also decrease.

Answer:

A. The number of snails and birds decrease.
