Question

A population is a group of:
A. Individuals in a species
B. Species im a community
C. Communities in an ecosystem
D. Individuals in a family

Answer 1

Hint: A population is characterised as a group within a given area of individuals of the same species living and interbreeding. Population members also rely on the same resources, are subjected to similar environmental restrictions, and are dependent on other members' availability to continue over time.

Complete Answer:
- The organisms of a population usually remain confined to the same geographical area. Individuals do not breed with individuals of other groups. A population means a group of organisms that are of the same species living in the same area.
- The organisms of the same population are capable of interbreeding and live in a particular geographical area whereas interbreeding is possible between any area is called the area of sexual reproduction.
- By measuring density, size, sex ratio We can measure the status of a specific population. The way of interaction of individuals with their surrounding environment indicates the behaviour and health of the population. There is great importance of population density in the studies of ecological systems.
- The organisms of the same population are capable of breeding and live in a particular geographical area that interacts with each other. So, a biological community of interacting organisms and their physical environment constitutes a stable ecosystem, where different types of community interactions such as mutualism, competition, predation, commensalism and parasitism etc.
- The loss of biodiversity, climate change, pollution, deforestation, scarcity of water and food are all compounded by our immense and growing numbers. A product of our consumption and our numbers is our effect on the climate. We've got to fix them.

So, the correct answer is option A i.e, individuals in a species.

Note: A population's health and behaviour is influenced by the way certain people communicate with each other and with their surrounding environment. By measuring and calculating elements common to all populations, such as size, density, fecundity, mortality, sex ratio, and age structure, we can assess the status of a population. These demographic statistics provide standardised indicators for researchers to compare populations and assess extinction risk.
