Answer:
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
A is the answer for this problem

Answer:
Option A, Release of chemical signals by keratinocytes that have been damaged by UV light will increase the production of melanin.
Explanation:
Negtaive feedback mechanism of homeostasis maintains the stability of any internal condition or function through lessening of output of a system or through slow down of a functional system.
Here in this case the keratinocytes function is reduced by damaging them on exposure to UV light which further triggers the release of chemicals that enhance the production of melanin.
Hence, option A is correct
