Habitat loss refers to the destruction or alteration of the natural environments where plants and animals thrive. When habitats are lost, the species that depend on those environments for food, shelter, and reproduction often face significant challenges. As a result, many plant and animal populations decline due to the reduced space and resources available to them. This can lead to smaller populations, increased competition for the remaining resources, and ultimately, the risk of extinction for some species. Therefore, the decline in plant and animal populations is a direct and serious consequence of habitat loss, highlighting the critical relationship between environments and the survival of species.

The other choices suggest positive outcomes, which do not align with the reality of habitat loss; instead, they indicate improvements in biodiversity or ecological health that are not typically associated with a decrease in habitat area.
