What is population?
A population is an identified grouping of objects with the purpose of analysis and data collection. Examples include people and animals. It comprises a related collection of species that live in a specific area and have the ability to interbreed. In order to interbreed and produce fertile offspring, individuals in a population must be able to mate with other individuals.
- Genetic differences cause some people to be unable to survive and procreate.
- A local population may only occupy a small area or it may cover a larger area, representing the entire species.
Summary:
In the year 1999, the world population reached up to – (a) 1 billion (b) 3 billion (c) 6 billion (d) 7 billion
In the year 1999, the world population reached up to 6 billion. When individuals in one local population move to another local population, it creates a metapopulation. Due to various environmental and physical conditions that act as barriers to the population’s exponential growth, the majority of populations are unstable.
