Question

Правило гласит: «не более 10% энергии поступает от каждого предыдущего трофического уровня к последующему». Используя это правило, рассчитайте величину энергии, которая переходит на уровень консументов I порядка при чистой годовой первичной продукции экосистемы 200 кДж.

Answer 1

Ответ: 20 кДж

Объяснение: надо найти 10% от 200кДж.

(200/100)×10=20

Answer 2

Calculation of Energy Transfer to First Order Consumers

According to the given rule, "no more than 10% of energy is transferred from each previous trophic level to the next," we can calculate the amount of energy that is transferred to the first-order consumers.

The net annual primary production of the ecosystem is given as 200 kJ.

To calculate the energy transferred to the first-order consumers, we need to multiply the net primary production by the transfer efficiency, which is 10% or 0.1.

Therefore, the energy transferred to the first-order consumers can be calculated as follows:

Energy transferred to first-order consumers = Net primary production * Transfer efficiency

Energy transferred to first-order consumers = 200 kJ * 0.1 = 20 kJ

Therefore, the amount of energy that is transferred to the first-order consumers is 20 kJ
