Acloud forms during the water cycle. which of earth's spheres does this event occur in?

atmosphere

biosphere

hydrosphere

lithosphere

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."

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 

the answer is c on e2020, bud.
