Which is an example of matter cycling through the bodies of living things? A. Whales swimming in the ocean
B. Whales eating plankton
C. People visiting the aquarium
D. Plankton moving with the tide

B whales eating plankton

I would say B. whales eating plankton

Explanation: Whales eating plankton causes the plankton to travel through the digestive tract and be converted to energy, so that answer would probably be your best bet.

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
