B. Communities in an ecosystem
C. Individuals in a family
D. Individuals in a species

Answer 1

Hint: The organisms of a population same geographic area.
A population means a group of organisms that are of the same species.

Complete answer: In biology, a population refers to a group of individuals who belong to the same species and interact within the same space.
1. The organisms of the same population are capable of interbreeding and live in a particular geographical area, where inter-breeding is possible between any pair within the area is called the area of a sexual population.
2. By measuring the elements common to all populations e.g. density, size, sex ratio, fecundity, and age structure, it is possible to determine the status of the population.
3. The way individuals interact with each other and with their surrounding environment indicates the behavior and health of the population.

So, the correct answer is D. Individuals in a species

Note: All the populations together make a ‘universe’ (in biological terms).
1. Population density is of great importance in ecological studies.
2. It is one of the most significant indices of population concentration.
3. The number of individuals per unit of the geographic area indicates the density of a population.
