The option referencing nitrogen levels in the soil is not a basic requirement of wildlife species. Wildlife species, such as mammals, birds, and insects, generally require essential elements for their survival, which include cover, water, and food.

Cover provides shelter from predators and harsh weather, offering safety and a place for resting or nesting. Water is crucial for hydration and is necessary for many biological processes. Food is fundamental for energy and nutrient intake needed for growth, reproduction, and overall health.

While nitrogen levels in the soil play a critical role in plant health and growth, which can indirectly affect wildlife by influencing the food supply, they are not a direct requirement for the wildlife species themselves. Thus, ensuring adequate nitrogen levels is more of an ecological concern regarding plant communities rather than a direct need for the animals relying on those plants for sustenance.
