Ecological productivity and efficiency

What does ecology and ecosystem mean? How does ecosystem function? What is difference between ecological productivity and efficiency? These are some common questions everyone should know for environmental literacy. So, let’s learn about ecological productivity and efficiency.

Species diversity => Food webs => ecological productivity => ecological efficiency => origin of species => biodiversity…

As per this order, the cycle of nature moves constantly. Now, let’s understand all the concepts in detail.

Meaning and definition of ecology

Ecology is an offshoot of biology that deals with all the process in respect of interactions of organisms in the biotic world.

In other words, it is a careful understanding of interactions of different organisms in the process of production and consumption of energy by all means.

What is mean by ecological productivity?

Ecological productivity is a rate at which energy is produced by photosynthetic organisms in an ecosystem. In this process, all the autotrophic organisms convert solar energy into chemical energy for body requirement. And, remaining energy they store in the form of cellular energy.

The stored energy by these autotrophic organisms is termed as net ecological productivity that determines the rate of energy transfer from one trophic level to another.

Importance of Ecological efficiency

Ecological efficiency is the rate of energy flow or transfer from one trophic level to another by the means of interactions between autotrophs and heterotrophs.

In this case, net productivity of autotrophs determines the rate of energy transfer or flow between two trophic levels. More the productivity, higher the efficiency.

Why need species diversity?

Species diversity means the different varieties of species present in the each strata of trophic level of ecosystem.

Obviously, species diversity determines the richness of food chains and food webs in the given area. You know that our living world is abounds with countless species. That’s why we observes several food chains and food webs around us.

Species diversity => genetic diversity => evolution of new species…

Biologically, the amount of genetic variation enable a population to adopt to its environment and to respond to natural selection. Therefore, species diversity acts as a basis for speciation or evolution of new species.

Clearly, such species diversity is instrumental in maintaining food chains and food webs. In short, more the number of species, greater the rate of ecological productivity and energy transfer.

For clarity,

The degree of ecological productivity and efficiency of an ecosystem depends on the number of species in that trophic level. More the species diversity, higher the productive capacity and transfer of energy.
