Biodiversity is affected by climate, area, niche, genetic diversity, and *existing*. Please tell me if the word surrounded by (*) is true or false in the given sentence. It’s number 32

Biodiversity is affected by climate, area, niche, genetic diversity, and existing.
Existing doesn't make sense because is laking a substantive and it provides no information.
Biodiversity means the diversity of living beings, so the sentence could be corrected as:
Biodiversity is affected by climate, area, niche, genetic diversity, and existing species.
