 D.None of the above

Answer 1

Hint: The word ecosystem is made up of two words eco+system=Ecosystem in which Eco=related to environment
System=interacting groups
So, the ecosystem can be defined as the interaction of living and non-living entities(things) in our natural environment. The word ecosystem is the first stamp out by A.G Tansley in 1935. It is a structural and functional unit of ecology.

Complete answer:
As the ecosystem is made up of two things first is Living things and the second is nonliving things
Living things+Non living things=Ecosystem
Living things are a part of the biotic environment. And nonliving things are the part of the Abiotic environment.Producers are called Autotrophs and consumers are called Decomposers.
.Producers are the food producing organisms and consumed by primary consumers for living. They are more because the growth rate of producers is more than primary consumers. Primary consumers have a specific period In the year for reproduction but producers can reproduce any time in a year and the life expectancy of producers are much more than primary consumers. From the beginning of life on the earth Producers are much more than primary consumers.

Hence, the correct answer is option (A).

Note:Day by day the environment of the earth is depleting due access pollution on the earth so the balance between producers and consumers is unbalanced which is harmful for the next generation.If still humanity is not delighted it is harmful to the living entities to survive. By using solar energy and biogas wind energy etc, we can reduce pollution and can save our planet.
