Which organism lives in a colony with many others of the same cell type?

 The alga Volvox , or multicellular, as in the phylum Bryozoa. The former type may have been the first step toward multicellular organisms.

Explanation:

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
