Question

the coyote’s diet includes a wide variety of small mammals, livestock, birds, reptiles, carrion, fruit, and vegetables. it is one of the few animals that has enlarged its range since human encroachment began. which is the most likely reason for this?

• it has adapted its diet to include more variety, thereby increasing its food supply.
• it has intermingled with human pets, such as the dog, to increase its population.
• it has migrated to ranges with more favorable, moderate climates.
• it has an increase in nest and shelter sites within the urban and rural range.

Explanation:

To determine the answer, we analyze each option:

• Option 1: The animal's diet includes a wide variety of food sources (small mammals, livestock, birds, reptiles, carrion, fruit, vegetables). Adapting to a more varied diet would increase its food supply, allowing it to expand its range, especially with human encroachment providing new food sources.
• Option 2: Intermingling with human pets like dogs is not a typical or likely reason for a species to enlarge its range; there's no clear ecological or behavioral link here.
• Option 3: The question doesn't mention climate change or the animal moving to moderate climates. The focus is on human encroachment, so this is less relevant.
• Option 4: While shelter is important, the diet variety (which impacts survival and population growth) is a more direct driver for range expansion, especially with human - related food availability.

Answer:

A. It has adapted its diet to include more variety, thereby increasing its food supply.
