What advantage would there be for an organism if the signal transduction pathway had several amplification steps?

Amplification allows the reception of a single ligand to cause a response in several places in the cell, which allows an organism to respond to a stimulus more quickly.

yes it is   dangerous

explanation:

because that foot is discusting and could get you sick

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
