Answer:
C) seed eater
Explanation:
In nature, very often it happens that one organism kills another organism in order to get to nutrients, and in fact that is the case much more often than not. The herbivores are eating the plants, very often stripping them totally of their leaves, or even eat their roots and stems, resulting in a dead plant. The predators hunt their pray and kill it, thus it is their ''job'' to kill the other animals. The term carnivore is used for the meat eaters, again predators, so they directly kill other animals. The parasites are organisms that are not able to provide for themselves so they use a host organism. They attach to the host organism and slowly sucking out the nutrients from it, eventually it reaches a point when the parasite has sucked every nutrient out of its host and kills it, moving on to another host. The seed eaters though seem to be the least harmful. They do not kill any organism, nor do they destroy the vegetation, but instead they feed on the products from the vegetation, so the chances that a seed eater will kill the organism that provides its food are almost non-existent.
