Question

1. an ecosystem includes this food chain. pine seed → mouse → snake → hawk what would happen if all the mice died from a disease? ① the snakes would eat pine seeds instead of mice. ② the producers would stop making food. ③ the population of snakes would increase. ④ the population of snakes would decrease.

Explanation:

In a food chain, each organism has a specific role. Snakes rely on mice as a food source. If mice die out, snakes lose their food. Snakes can't eat pine seeds (they are not herbivores). Producers (pine seeds) don't stop making food because of mice's death. Without food (mice), snakes' population would decrease, not increase.

Answer:

D. The population of snakes would decrease.
