Barnacles and mussels compete for space on rocks. which of the following is another good example of an interaction that is best described as competition, not predation or parasitism?

a-clownfish live in the tentacles of sea anemones, gaining protection from predators that avoid being stung or caught by the sea anemone while dropping small pieces of food for the anemone.
b-lampreys attach to the side of a fish and use their rasp-like teeth to cut through the fish's scales, allowing them to consume the fish's blood.
c-remoras attach to sharks and break the shark's scales (scutes), allowing them to consume mucus produced by the shark's internal organs.
d-several species of nematode worms can all live in the intestines of marine fish; the presence of one type may limit space and nutrient availability for other types.

D-Several species of nematode worms can all live in the intestines of marine fish; the presence of one type may limit space and nutrient availability for other types.

Explanation:

In ecology, competition can be define as the struggle between the two species which may or may exhibit the same niche. These two species are expected to compete for the same type of resource. The two species may compete for resources like food, shelter, water, substrate, light and territory. Also the members of the same species may compete for mates for conducting the process of copulation.

Predation is a process in which one organism obtain food by killing another organism. Parasitism is a symbiotic relation in which two species lives in close association but only one species obtains the benefit and the other species get harmed.

D-Several species of nematode worms can all live in the intestines of marine fish; the presence of one type may limit space and nutrient availability for other types. is the correct option. This is because of the fact that the nematode worms are competing with other worms for resources like space and nutrients residing inside the intestines. Hence, it is the example of competition instead of predation and parasitism.

answer; i believe the answer is (polygenic inheritance;
