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

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).

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
