What are the different types of feeding relationships?

Answer 1

I'm not sure what you mean by "feeding relationships", but I think this is what you mean.

Cannibalism is an intraspecific interaction in which the larger members eat up the smaller ones of their own species. An individual that eats is known as a cannibal, and the one eaten as a prey.

Symbiosis is a relationship between organisms of different species for the purpose of nutrition. Examples of symbiosis include parasitism, mutualism and commensalism.

Neutralism is when a species may not be affected by the presence of other species in its environment. Scavenging is the act of feeding by an animal on the remains of dead animals and other refuse.

Amensalism is an interaction in which one species causes harm to another species with its toxic secretion, often without gaining any benefit from the interaction.

Parasitism is when an organism that feeds in or on another living organism, which is called the host, and which does not benefit and may be harmed by the relationship. Parasites of man include fleas, lice and tapeworms.

Predation is the interaction between two species, one of which captures, kills and eats up the other. The prey is the animal that is hunted for as food and the predator is the animal that feeds on other animals (a predator is a food consumer but is not a parasite). The relationship between predator and prey can have dramatic effects on their numbers and on the food chain.
