Answer:
I answered your other one so I'll help out again.
Step-by-step explanation:
If the animal is overeating, that could affect the plant population by a low abundance of pollination. If the animal is a human then many things can go wrong. Humans chop down plants which also hurts the animals eating them. It's like the pandas in China. Pandas have to eat a lot, which means their food source is already low. And with humans chopping down their homes it now only kills the plants, but it also kills the pandas.
