How would the toucan population be affected if the population of trees in its habitat decreased dramatically? a. the birds would be able to find mates and reproduce more successfully, so the toucan population would increase. b. competition for food and shelter would increase, so the toucan population would decrease. c. the birds would be able to find food more easily, so the toucan population would increase. d. the change in the tree population would have no effect on the toucan population.

The correct answer is B. Competition for food and shelter would increase, so the toucan population would decrease.

Explanation:

Birds such as toucans rely on trees to obtain food, shelter and a place to nest. Due to this, a decrease in the population of trees would cause food, shelter, etc. are limited, and therefore not all toucans can have access to it. This situation will lead to competition between toucans, and a decrease in the population of these birds. This decrease would be the result of toucans having fewer chances to survive and reproduce because food and shelter play an important role in these two aspects. According to these ideas, it is likely "competition for food and shelter would increase, so the toucan population would decrease".
