Coyotes will decrease
B
More coyotes will be born.
C

D
None of the above
Explanation: 

Detailed explanation-1: -With no predators to control the population and alter feeding behavior, the prey species quickly degrade and over-run its habitat. As food becomes scarce, the population becomes sick and malnourished, and will either move or crash.

Detailed explanation-2: -If an organism is removed from the food chain, it spoils the flow of energy and nutrient in the ecosystem. It disrupts the balance of the food chain. As a result, the organisms which depend on others for food will die due to starvation.

Detailed explanation-3: -WHY ARE THERE FEWER PREDATORS THAN PREY? Predators are fewer in number than prey because they are higher up the food chain. In a food chain, an organism passes on only part of the energy it receives from food. With less energy, each level in a food chain supports fewer individuals than the one below it.

Detailed explanation-4: -Keystone species have low functional redundancy. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche. The ecosystem would be forced to radically change, allowing new and possibly invasive species to populate the habitat.
