Match the terms to their correct definition.
A. A group of organisms of the same species that live in an area.
B. All of the living and nonliving things in a particular area.
C. A complete living thing that carries out the processes of life.
D. All of the living things in a particular area.
The Correct Answer and Explanation is:
Here are the terms matched to their correct definitions:
A. Population – A group of organisms of the same species that live in an area.
B. Ecosystem – All of the living and nonliving things in a particular area.
C. Organism – A complete living thing that carries out the processes of life.
D. Community – All of the living things in a particular area.
Explanation:
- Population (A) refers to a group of individuals of the same species that occupy a particular area. A species is a group of organisms that can interbreed and produce fertile offspring, and populations are formed when these individuals live together and interact within a given environment. For example, a population of wolves in a forest would include all the wolves of that species living in that forest area.
- Ecosystem (B) is a broader term that encompasses all the living organisms (plants, animals, microorganisms) and non-living components (water, soil, climate, etc.) in a particular environment. The ecosystem concept highlights the interactions between biotic (living) and abiotic (non-living) elements. For instance, a pond ecosystem would consist not only of the plants and animals within the pond but also the water, nutrients, and atmospheric factors affecting them.
- Organism (C) is the basic unit of life. An organism is any living thing that can carry out the necessary processes for life, such as respiration, growth, reproduction, and responding to stimuli. An individual wolf, tree, or bacterium is an organism, as each can independently perform the essential life functions.
- Community (D) refers to all the living organisms in a particular area. This includes different populations of species interacting with one another within the same geographic region. For example, in a coral reef community, there might be populations of fish, corals, crabs, and other marine life, all interacting with each other.
Understanding the relationships between these concepts is essential for grasping the organization of life on Earth. Each level—from the individual organism to the entire ecosystem—plays a role in maintaining the balance of natural systems.
