If both natural vegetation and wildlife are declining, what does the basic relation show?

Pressure on habitat and food chain

Natural vegetation supports wildlife in two basic ways: it provides places to live and supplies food directly or indirectly. Plants form the lower levels of many food chains, so insects, herbivores, and then carnivores depend on them. When forests, grasslands, or other natural habitats shrink, animals may lose shelter, breeding areas, and feeding grounds. The decline of vegetation can therefore lead to falling wildlife numbers and greater competition for remaining resources.

Option A is correct because it identifies pressure on habitat and the food chain. A change in language has no direct ecological explanation. River length does not normally increase because vegetation and wildlife decline, and the end of photoperiod is not a valid description of this relationship. Protecting vegetation is consequently an important part of conserving wildlife and maintaining ecological balance.
