The picture below shows a group of water skate bugs “walking” on the surface of a pond. When insect lands or falls into the water, the water molecules vibrate. The water skater uses the resulting vibrations to find its prey. What property of water enables this bug to stay on the surface of the pond and not sink?

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
