Correct answer: majority

Explanation: The word 'majority' refers to the greater part of something, which in this context means that most of the world's terrestrial biodiversity is found in forests. This fits grammatically as it serves as a noun that complements the subject of the sentence, aligning with the context of discussing biodiversity.

Meaning: 'Majority' means the greater number or part of something, in this case, referring to the largest portion of terrestrial biodiversity found in forests.

Correct answer: mitigate

Explanation: The word 'mitigate' means to make something less severe or serious, which is relevant in the context of forests helping to reduce the impacts of climate change. It fits grammatically as a verb that describes the action performed by forests.
