The correct answer is D) Population
Step-by-step explanation:
In biology, the word "population" refers to the number of individuals or organisms of the same species that can be found in one specific ecosystem or area. For example, it is estimated the population of elephants in Africa is round 700,000. Additionally, the main feature that defines a population is that members of the opposite sex can interbreed and this results in new individuals that are fertile. Besides this, the populations are essential factors of ecosystems as a decrease or increase in the population has a great impact on other populations of organisms. The previous ideas imply the term that names the group of individuals of the same species living in the same area is Population.
