Question

24 If 10,000 J of energy fall on piece of land, then
is energy available at T, level?
(1) 1000 J
(2) 10J
(3) 100 J
(4) 11​

Answer 1

Answer:

1 J

Explanation:

10000J of energy falls on land

producer gets 1000J

herbivores get 100J

carnivores get 10J

top carnivores get 1 J

energy is lost by 10% at every trophic level

Answer 2

The energy available at T level will be 1 Joule according to the 10% rule.

Explanation:

According to the 10% rule, at each level starting from producers to the consumers, there is a 10% of loss in the energy and this is the reason that top consumers receive less amount of energy.

10000 Joule of energy is falling on land.

So,

• Energy at primary producer level = 1000 J
• Energy at primary consumer level = 100 J
• Energy at secondary consumer level = 10 J
• Energy at tertiary consumer level = 1 J
