Question

A light-colored insect lives on trees in a forest. The bark of the trees appeared white because of light-colored lichen (plant) that also lived on the tree. Disease destroyed the lichen. The tree bark is now dark-colored. How will this environmental change affect the number of light-colored insects?

A) The number of light-colored insects will decrease because predators will see the light-colored insects on the dark bark more easily
B) The number of light-colored insects will decrease because, with the lichen gone, the insects will have no other source of food
C) The number of light-colored insects will increase because, with the lichen gone, the insects will no longer have to compete with the lichen for space
D) The number of light-colored insects will increase because the insect predators that also eat the diseased lichen will become ill and decrease in number

Answer 1

Answer: correct answer is A

Explanation: The number of light-colored insects will decrease because predators will see the light-colored insects on the dark bark more easily
