Document Summary
Competition: when species compete for a resource in short supply. Predation: refers to interaction where one species, the predator, kills and eats the other, the prey. Herbivory: interaction in which an herbivore eats part of a plant or algae. Symbiosis: relationship where two or more species live in direct and intimate contact with one another; clownfish and sea anemone. Fundamental niche: includes the total range of environmental conditions that are suitable for existence without the influence of interspecific competition or predation from other species. Realized niche: a phrase relating to ecology defining the actual space that an organism inhabits and the resources it can access as a result of limiting pressures from other species. Cryptic colouration: camouflage, this makes the prey difficult to spot. Aposematic colouration: these animals have chemical defense and have bright warning colouration. Batesian mimicry: a palatable or harmless species mimics an unpalatable or harmful model. M llerian mimicry: two or more unpalatable species resemble each other.
