Question

analyze this: a vine grows up a tree to reach sunlight. the tree begins to die because the vine blocks its light. is this commensalism? yes, because the vine benefits. yes, because the vine is just living there. no, it has become mutualism because they are touching. no, it has become parasitism because the tree is now harmed.

Explanation:

Commensalism is a symbiosis where one organism benefits and the other is unaffected. Here, the vine initially may have seemed to just use the tree, but the tree is now dying from blocked light, so the vine harms the tree. Parasitism is when one organism benefits at the expense of the harmed host.

Answer:

No, it has become parasitism because the tree is now harmed.
