Consider the following food chain:
grass β†’ grasshopper β†’ mouse β†’ snake β†’ hawk.
What percentage of the chemical energy
fixed by photosynthesis of the grass
(100%) is available to the hawk?
01%
1%
1%
10%

Respuesta :

Answer:

0.01%

Explanation:

If the grass is 100%, then the grasshopper is 10%, the mouse is 1%, the snake is 0.1%, and the hawk is 0.01%. When you go up the trophic levels, you only get 10% of the energy left behind from the last level (in other words, you move the decimal point to the left by 1 place).

The food chain shows the percentage of energy that is available to the hawk which is in the form of 0.1% i.e option A is correct.

What is a food chain?

The food chain is the web of food that flows a sequence of decreases of energy from the source and the law of energy follows the 10% law as for each and every stage of the ecological system there is drop of 10% energy used by the organisms.

The available energy at the bottom of the food chain is 100% which decreases to 10% in grasshopper is the primary consumer, this energy further decreases to 1% in secondary and tertiary consumers, and finally less than 1% is available for the hawk.
