Which part of an ecosystem would be hurt if humans overhunted an herbivore
Anna71 [15]
Herbivores are those animals that feed only on plants. Herbivores are food for carnivores, which feed on other animals. If a particular herbivore is over hunted by man, the particular carnivore that feed on that over hunted herbivore will be affected, because its source of food has been wiped out. Thus, it will have one less choice when it comes to food and it will have to concentrate on other type of herbivore as source of food. Thus, other herbivores in that particular ecosystem will be affected too.
