Question

An example of biotic components in nature is
A.Cells
B.Organic molecules
C.Plants
D.All of the above

Answer 1

An ecosystem is particularly defined as a self-regulated and self- sustained unit having interaction and exchange of materials between the biotic community and physical environment. Thus, it is composed of two components- biotic and abiotic components. It keeps check on functional balance or relatively stable state of equilibrium amongst its various components.

Complete answer:
The two important factors that are responsible for forming the environment are biotic components and abiotic components. All living beings in an environment are usually said to be biotic factors, and abiotic factors apply to all non-living components as for example physical conditions such as temperature, humidity, pH, salinity, etc. and chemical agents such as different gases, mineral nutrients, etc.
Biotic components are defined as any living component that helps to form the environment or has an influence upon another organism. This is composed of both animals eating other organisms within their habitat, and the organism being eaten.

Now let us find solution from given options:
Cells: cell is usually defined as the structural and functional component of all living beings. So it is living in nature. These cells carry all the metabolic activities inside a living being used to maintain living structure.
Organic molecules: organic molecules are defined as carbohydrates, lipids , proteins and some other compounds that make the components of a living defined body. These compounds are involved in the metabolic reactions so are considered living.
Plants: plants are the organisms that prepare their own food by using sunlight, air and produce energy. They are living cells as they respire, breathe and also, they show growth which are essential characteristics of living beings.
All of the above: all of the above given options are true.

Hence, the correct answer is option (D)

Note: Both the biotic and abiotic components are mutually related to each other. as when we assume that, if one of the components is removed or changed, the whole ecosystem will face its consequences.
Unthinkingly, abiotic factors directly influence species survival.
