F the plankton contain 100,000 kcal of energy, about how much energy will the manta ray obtain from eating the starfish? 10 kcal 100 kcal 1,000 kcal 10,000 kcal

100kcal

Explanation:

The law in energy transfer in the food chain is that only 10% of total energy is transferred.

The food chain between the plankton and starfish follows;

Plankton - Mussels and Oysters - Starfishes - Manta Ray

Plankton being the producer produces 100,000kcal

Mussels/Oysters get 10% of 100,000kcal= 10,000kcal.

Starfish gets 10% of 10,000kcal = 1,000kcal

Manta Ray being the final consumer of starfish gets 10% of 1,000kcal = 100kcal
