This is the picture to my last question about the triangle.

6 units

Step-by-step explanation:

Area = base x height

So if the area is 24 and the height is 4 that means you must have a number that equal 24 when multiplied by 4 which is 6.

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
