forest reserves
protecting

Explanation:

The question is about forest conservation methods. The context is protecting biodiversity and ecosystem functions. "Protecting" is a verb that fits the sentence structure (__ forests), and "forest reserves" is a noun phrase. The sentence structure requires a gerund or verb - like form to modify "forests", so "protecting" makes sense as "Protecting forests" is the subject of the sentence, while "forest reserves" would be "Forest reserves" as a subject, but the structure here needs a word that functions as a verb - ing (gerund) to form the subject. Wait, actually, looking at the sentence: " forests is the most effective way...". The subject should be a noun or a gerund phrase. "Protecting forests" is a gerund phrase (verb - ing + object) acting as the subject, while "forest reserves" would be "Forest reserves" (a noun phrase) but the sentence structure here, with "is the most effective way...", the subject should be an action or a thing. But the options are "forest reserves" and "protecting". Let's check grammar: "Protecting forests is the most effective way..." (gerund phrase as subject) is correct. "Forest reserves forests" would be incorrect. So the correct option is "protecting"? Wait, no, maybe I misread. Wait the dropdown has "forest reserves" and "protecting". Wait the sentence is "__ forests is the most effective way...". So the blank is before "forests". So "Protecting forests" (gerund + object) or "Forest reserves forests" (which is wrong). So the correct word is "protecting"? Wait no, maybe the dropdown is a typo, but among the two options, "protecting" is a verb - ing that can form the subject "Protecting forests", while "forest reserves" would be "Forest reserves" as a subject, but then the sentence would be "Forest reserves forests is...", which is incorrect. So the correct option is "protecting"? Wait, no, maybe I made a mistake. Wait the options are "forest reserves" and "protecting". Let's re - examine: the sentence structure is [Blank] forests is the most effective way... So the blank needs a word that, when combined with "forests", forms a subject. "Protecting" is a gerund, so "Protecting forests" is a valid subject (gerund phrase). "Forest reserves" is a noun phrase, but "Forest reserves forests" is not a valid phrase. So the correct option is "protecting".

Answer:

protecting
