4. D.    a taxonomic domain

Summary Introduction

Introduction:

An organism is the smallest level of organization in terms of ecology. Taxonomically, organisms are divided into many different species.

Answer to Problem 1TYU

Correct Answer:

A community is defined as a geographical area which consists of different populations in a given time period.

Therefore, option (B) is correct.

Explanation of Solution

Reason for the correct statement:

A campus consists of a many different types of populations. The humans studying there make up one kind of population and others are formed by the different plants, trees, birds, insects etc. A community is also made up of different types of populations within an area over a time period.

Option (B) is given as “a community”.

“All the organisms on your campus make up a community”, it is the right answer.

Hence, the option (B) is correct.

Reasons for the incorrect statements:

Option (A) is given as “an ecosystem”.

An ecosystem consists of the non-living matters too, along with the living organisms. However, we are talking only about the living organisms. So, this is a wrong answer.

Option (C) is given as “a population”.

A population consists of organisms of the same species. However, the campus consists of many numbers of species. So, this is a wrong answer.

Option (D) is given as “a taxonomic domain”.

A domain is the highest in hierarchy in the classification system and encompasses a large number of organisms. So, this is a wrong answer.

Hence, options (A), (C) and (D) are incorrect.

Conclusion

All the organisms on a campus make up a community. A community is defined as a geographical area which consists of different types of populations in a given time period.
