Mountain pine beetles inject a fungus into the trunks of pine trees.
What is the best explanation of trees infested with mountain pine beetles turning red and dying?
Select one:
a. The tree cannot produce cones anymore
b. The tree cannot move gases in and out through the needles
c. The weight of the tree cannot be supported in the soil
d. The tree cannot move water and food to all its parts*
I agree
Okay, I will put that, and I'll update if it was correct or not just in case. Thanks
The best explanation for trees infested with mountain pine beetles turning red and dying is:
d. The tree cannot move water and food to all its parts.
This is because when the mountain pine beetles infest the tree, they disrupt the tree's circulatory system by burrowing into the inner layers of the bark. This burrowing activity damages the phloem, which is the tissue responsible for transporting water, nutrients, and sugars throughout the tree. As a result, the tree cannot effectively move water and food to all its parts, leading to nutrient deficiency and ultimately causing the tree to turn red and die.
