The Skin weren’t preserved at all

Explanation:

One reason why most fossilized animals have incomplete remains is that parts like the skin aren't usually preserved at all. There are however some instances in which the skin are preserved but it’s very rare.

This is because of the action of decomposers on the remains of the body parts and the presence of scavengers which eats the body parts thereby making the remains incomplete.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
