4. In what temperature range is amylase active?

40 degrees c

Explanation:

it shows a spike so the most active.

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 

and after water is usually warmed by the sun the water temperature raises and then evaporates .
