An outher orginisim eats it
"when a hawk dies it gets eaten by another bigger animal."
It can be either one. If it is eating another animal, like a bird or a mouse, then it's a predator. If it is being eaten by another animal, like a great horned owl or a coyote, then it is prey.
The chemical energy of the animal who was eaten is passed on to the animal who ate the other animal.
Prey are things that get eaten by bigger things.
Yes. It happens regularly.
Coyotes are rarely eaten by anything. Your hungry wolf might though.
A mink
Not if you keep it private, but otherwise it could be considered animal cruelty. Unless you can prove it was endangering your life.
No. A predator eats other animals called prey.
The arrmor means that the animal is getting eaten by another animal.
The animal that's been eaten has already used a great deal of the food energy it has consumed in living to that point. As for the food energy (calorie) value of what's there at the time of death and consumption -- only a fraction of that is consumed (unless the whole carcass is eaten) by its prey and only a fraction of that is converted to food energy through its digestive process.
When a plant or animal is being eaten, it is called consumption. When an animal eats another animal, the animal doing the eating is a predator or scavenger or carnivore or omnivore and the animal being eaten is the prey.
