Describe each of the following species interactions and give an example of each: (a) interspecific competition (b) intraspecific competition (c) predation (d) territoriality (e) symbiosis.

Explanation:

(a) interspecific competition: It is a kind of competition that occurs between the individuals that belong to different species competing for the same resource in an ecosystem. For example, lion and tiger populations thriving for the same type of prey that is deer population.

(b) intraspecific competition: Interspecific competition occurs between the members of the same population competing for limited resources. For example, trees of the same species competing for the sunlight and soil nutrients.

(c) predation: It is an ecological interaction that occurs between the superior or inferior species. One animal kills other animal to obtain it as a source of food. For example a tiger kills a deer to obtain it as food.

(d) territoriality: It is a quality of a species or a population of species to obtain the geographical area to an extent or limit where no other species or population can intrude. For example, lion shows the territory behavior to protect their children from predators.

(e) symbiosis: It is a type of biological interaction in which two species lives in association with each other. This interaction can be mutualistic, parasitic or commensalistic. For example, a lice sucking blood from animal is an example of parasitic symbiosis.
