NEET BIOLOGY

Detailed explanation-1: -Interspecific competition is when different animals that live in the same geographic area (sympatric species) compete for the same set of resources, mostly food and space.

Detailed explanation-2: -A population is a group of individuals of the same species that live in the same geographic area that interbreed with each other.

Detailed explanation-3: -Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea (/ˌæstəˈrɔɪdiə/). Common usage frequently finds these names being also applied to ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as asteroids due to being in the class Asteroidea.

Detailed explanation-4: -Species interactions within ecological webs include four main types of two-way interactions: mutualism, commensalism, competition, and predation (which includes herbivory and parasitism). Because of the many linkages among species within a food web, changes to one species can have far-reaching effects.

Detailed explanation-5: -Competition can be a powerful force affecting the abundance of populations. Competition will reduce the amount of available resources to each species, when that resource is in short supply. In most of the cases the effects of competition are asymmetrical or unequal. That is, one species is harmed more than the other.
