Answer 1

A.The mark Recapture technique is used where it is impratcical to count every individual.Capture a small number of individual put a harmless mark and relaese them back. Catch another small group and record how many have a mark and so on.In this way this technique is used to estimate a population size.

B.There are two types of competition in ecology.Interspecific competition and Intraspecific competition.

Competition between same species is a positive species interaction as it leads to evolution of better adaptations in a species.

C.Fundamental niche is the entire set of conditions under which an animal can survive and reproduce itself.

D.Realized niche is the range of environmental conditions under which the species is really found.

E.Mullerian mimicry is a form of mimicry where two equally noxious species evolve to look similar to each other.

F.Batesian mimicry is a form of mimicry wherein one harmless species that is palatable to a predator,mimics the appearance of a harmful or noxious species.
