Consider the following food chain: garden plants are eaten by snails, which are eaten by birds, which are eaten by the household cat. what happens to the other members of the food chain if the garden is removed? a. the number of snails and birds decrease. b. the number of snails increases, while the number of birds decreases. c. the number of snails decreases, while the number of birds increases. d. the number of snails and birds increase.

a. The number of snails and birds decrease.

A food chain refers to the sequence of events in an ecosystem, where energy in the form of food is transferred when one organism is eaten up by another. Energy in a food chain transfers from primary producer to higher consumer level. Here, the example of food chain is garden ecosystem.  If this garden ecosystem is removed this will affect the organisms which are sustaining their life in garden. Garden plants are eaten by snails, which are eaten by birds, which are eaten by the household cat. Snails being primary consumers and birds are secondary consumer will decrease in population if garden is removed.
