You need more context to answer this.
Energy available to krill is 1500 calories
<u>Explanation:</u>
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 = 
= 1500 calories
Energy available to small fish = 
= 150 calories
Energy available to medium fish = 
= 15 calories
Energy available to large fish = 
= 1.5 calories

Good Luck
1. Do a pun-net square.
R r
r
r
2. The offspring would be Rr, rr, Rr, rr
3. 2 of them are heterozygous(Rr),which means they would be most likely rough coats
4. Two of them are homozygous for short hair (rr) which means they are going to be soft hair.
5. Your answer is
Rr, rr
