Question

Which of the following represents the biodiversity of an area?
(a) Gene
(b) Species
(c) Ecosystem
(d) All of the above

Answer 1

Hint: This is a community or group of living organisms that live in and interact with each other in a specific environment. It contains both biotic or living, parts, as well as abiotic factors, or nonliving parts.

Complete answer:
The ecosystem represents the biodiversity of an area. A group of living organisms in association with the nonliving components of their particular environment in which they are interacting with each other as a system is known as an ecosystem. Through the nutrient cycles and energy flows these biotic and abiotic components are linked together. Energy enters the system through the process of photosynthesis and is incorporated into plant tissue. By herbivores which are feeding on green plants and the herbivores are eaten by carnivores or omnivores or on one another the energy enters the system. The animals play an important role in the movement of matter and energy through the system. The animals also influence the quantity of plant and microbial biomass present in an ecosystem. The decomposers release carbon back to the atmosphere with the breakdown of dead organic matter and thus facilitate nutrient cycling by converting nutrients that are stored in dead biomass back to a form that will be easily employed by plants and other microbes. Both the external and internal factors are responsible for controlling an ecosystem. The external factors that control the general structure of an ecosystem but are not themselves influenced by the ecosystem include climate, parent material which forms the soil, and topography. Unlike external factors, internal factors are controlled, for instance, decomposition, root competition, shading, disturbance, succession, and therefore the sorts of species present.
The variability of living species on Earth, including plants, animals, bacteria, and fungi is said to be the biodiversity of living species.

So, the correct answer is option (c), ’Ecosystem’.

Note:
- Biodiversity is a term used to describe the numbers of varieties of life on Earth including plants, bacteria, animals, and humans.
- It is often used more specifically to ask all of the species in one region or ecosystem.
- The animals also influence the quantity of plant and microbial biomass present in an ecosystem.
- Both the external and internal factors are responsible for controlling an ecosystem.
