Energy available to krill is 1500 calories
Explanation:
Energy produced by phytoplankton = 15,000 calories
Energy available to krill = ?
Along the food chain, only 10% of energy is transferred to the organism of higher trophic level.
Thus,
energy available to krill = [tex]\frac{10}{100} X 15,000[/tex]
= 1500 calories
Energy available to small fish = [tex]\frac{10}{100} X 15,00[/tex]
= 150 calories
Energy available to medium fish = [tex]\frac{10}{100} X 150[/tex]
= 15 calories
Energy available to large fish = [tex]\frac{10}{100} X 15[/tex]
= 1.5 calories
