How could human activity disrupt the habitat and niche of an organism like the gray fox?
BlackZzzverrR [31]

Answer:

Disruption such as deforestation or mining can destroy the habitat, leading to water pollution, mud slides, and loss of soil. With the habitat affected, the animals the grey fox feeds on, such as rabbits or mice, will be affected as well, leading to the grey fox losing a source of food. By limiting the diet of the grey fox, other predators will be more likely to compete with the grey fox, disrupting its niche.
