Question

Do predators really kill only the old and sick prey? Please give me a answer

Answer 1

No predators usually target young and or healthy prey. Though prey that old and sick are easier to get. Those in a herd who are weak will fall behind which will make it easy for their predators to catch. Their hunters don't get the same 'nutrients' because of their ill body won't provide the same amount they would if healthy.

Answer 2

No, They find the alone one because they are easier to catch when away from the tribe. They are easier to kill when they are old and sick, or weak.
