Question

a mature, healthy eastern hemlock tree (left) and a branch infested with hemlock woolly adelgids (right), which can lead to the tree’s death. complete the statements. - in north america, the hemlock woolly adelgid is considered a(n) dropdown species because it is dropdown its native range and causes harm to native hemlock trees. - when hemlock woolly adelgids kill an eastern hemlock tree, the tree dropdown capture and store carbon through photosynthesis. this dropdown carbon fixation—an ecosystem service provided by hemlock trees.

Explanation:

First Statement:

1. For the first blank: An invasive species is a non - native species that causes harm to the native ecosystem. The hemlock woolly adelgid is not native to North America and harms native hemlock trees, so it is an "invasive" species.
2. For the second blank: Since it is invasive, it is "outside" its native range (it is not from North America, so it is outside its original native area).

1. For the first blank: A living tree can capture and store carbon through photosynthesis. When the tree is killed by the adelgids, it can no longer perform photosynthesis to capture and store carbon, so the tree "can no longer" capture and store carbon.
2. For the second blank: Since the tree can no longer capture and store carbon, this means it "reduces" (or in this context, stops) carbon fixation. The ecosystem service of carbon fixation is diminished because the tree is dead and can't do photosynthesis - based carbon fixation anymore.

Answer:

s for First Statement:
First blank: invasive
Second blank: outside

Second Statement:
