Detailed explanation-1: -Populations are groups of organisms of the same species living in the same area at the same time. They are described by characteristics that include: population size: the number of individuals in the population. population density: how many individuals are in a particular area.

Detailed explanation-2: -A population is a group of individuals of the same species that live in the same geographic area that interbreed with each other. Many species consist of multiple populations dispersed over a few to many geographic areas.

Detailed explanation-3: -According to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring.

Detailed explanation-4: -For example, populations living in different ecological environments (e.g., desert versus forest habitats) might undergo divergent and adaptive evolutionary change via divergent natural selection. These same evolutionary changes can also result in the populations evolving into separate species.

Detailed explanation-5: -Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi.
