In a community, autotrophs generate 1,000 calories per hour of GPP and 500 calories per hour of NPP. Primary consumers convert 10 calories per hour into their own biomass. What is the ecological efficiency in the link between autotrophs and primary consumers in this community?

1 percent

2 percent

20 percent

10 percent

Solution

Given

Autotrophs generating calories per hour of GPP [tex]= 1000[/tex]

Autotrophs generating calories per hour of NPP [tex]= 500[/tex]

The rate at which the primary consumers convert calories per hour into biomass is equal to [tex]10[/tex] calories per hour

The ecological efficiency is equal to" the rate of calorie conversion to biomass" divided by the net produced calories multiplied by [tex]100[/tex]

Rearranging the above relation in a mathematical equation, we get -

[tex]\frac{10}{500} * 100\\= 2[/tex]

Hence, option B is correct

The study of the environment is called ecology. The interaction between the living and the non-living substance is called the ecosystem.

The provided question is incomplete, kindly provide the complete question with the option. The correct answer to the question is option B.

What is GPP?

GPP stands for gross primary productivity.
It is defined as the total amount of energy produced by the plants in a given ecosystem.

According to the question,

Autotrophs generating calories per hour of GPP is 1000
Autotrophs generating calories per hour of NPP is 500

The rate at which the primary consumers convert calories per hour into biomass is equal to 10 calories per hour. The ecological efficiency is equal to" the rate of calorie conversion to biomass" divided by the net produced calories multiplied by 100

After solving the equation, the solution we get is as follows:-

[tex]100* \frac{10}{500} \\\\=2[/tex]

Hence, option B is correct
