Population Ecology and Age Pyramids — NEET Biology
📚 Practice ConceptEvolutionary changes through natural selection take place at the population level and hence, population ecology is an important area of ecology. A population is a group of individuals of a given species sharing or competing for similar resources in a defined geographical area. Populations have attributes that individual organisms do not- birth rates and death rates, sex ratio and age distribution. The proportion of different age groups of males and females in a population is often presented graphically as age pyramid; its shape indicates whether a population is stationary, growing or declining.
Assertion (A): A population is a group of individuals of the same species sharing resources in a defined geographical area. Reason (R): Population ecology links ecology to population genetics and evolution.
View solution & NCERT explanation
Correct answer: A — If both assertion and reason are true and the reason is the correct explanation of the assertion.
Both statements are true from NCERT. The Assertion defines population: “A population is a group of individuals of a given species sharing or competing for similar resources in a defined geographical area.” The Reason explains WHY population study is important: “Population ecology is, therefore, an important area because it links ecology to population genetics and evolution” - showing the evolutionary significance.
