if 2000 kcal of energy would be available in grass, how much energy would be availabele to the cow that eats the grass? to the human that eats the cow?

Generally, consumers only receive 10% of the energy from what they eat. So, if the grass had 2000kcal of energy, then the cow would receive 10% of that -  200kcal. And then when a human eats the cow, it will only receive 10% of the cow's energy. This is because within a food chain, energy is lost as organisms use their energy to survive - like moving and producing heat (if endothermic). So consumers do not get 100% of their food's energy. Hope this helps a little.

if 2000 kcal of energy would be available in the grass, the energy would be available to the cow that eats the grass - 200 Kcal and to the human that eats the cow - 20 Kcal.

When organisms are consumed in the food chain approximately 90% of total energy is lost as heat and only 10% of the total energy in the food is fixed into their body/flesh and is available for the next trophic level, this law is known as the law of energy flow or 10% law of energy flow.

In this consumers only receive 10% of the energy from what they eat then,

  • Grass has 2000 kcal of energy and the cow eats the grass which means the cow would receive 10% of the 2000 kcal -

=> [tex]\frac{2000 *10}{100}[/tex]  = 200 kcal . . . .1

  • When a human eats the cow, it will also receive 10% of the cow's energy which is 200 kcal -

=> [tex]\frac{200*10}{100}[/tex] = 20 Kcal

Thus, if 2000 kcal of energy would be available in the grass, the energy would be available to the cow that eats the grass - 200 Kcal and to the human that eats the cow - 20 Kcal.
