• E. A group of organisms that share similar ecological niches in different areas

Answer 1

The correct option is B All populations of different species that live and interact in the same area

The population is individuals of same species that occupy a specific area. The ecosystem is an assemblage of different species of an area and abiotic factors of a geographical area and also takes account of the interaction between them. The part of the earth where life exists is referred to as biosphere. A group of organisms that share similar ecological niches in different areas constitute species. The community is a group of populations of different species living together in a habitat and interacting with each other. Thus, the correct answer is B.
