A scientist is working on how genetic material like DNA is passed from one person to another. Which type of molecule is he working with?

O Carbohydrates

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 

b. to discover aspects of the natural world.

hopefully i .
