how many units of energy would there need to be to end up with 1000 units in the second? in the third? in the fourth?

Respuesta :

Answer:

10000 units in the second

100000 units in the third

1000000 units in the fourth

Explanation:

According to the pyramid of energy, which describes how energy flows from one trophic level to another, only about 10% of the available energy is transferred to the organism in the next trophic level as a lot of energy (about 90%) is lost as heat.

In this question, in order to have 1000inits of energy in

- Second trophic level = 1000 = 10/100 × x

10x = 100000

x = 10000units of energy

- for third trophic level,

100 × 1000

= 100000 units of energy

- for fourth trophic level;

1000 × 1000

= 1,000,000 units of energy.
