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?

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.

explanation:

image result for how many calories of energy will 20 grams of carbohydrates provide in one gram provides 4 calories

consuming the right balance of protein, carbohydrates and fat can you maintain a healthy weight and optimize your energy levels. protein and carbohydrates both contain 4 calories per gram, while fat provides 9 calories per gram.
