An airplane is flying at a altitude of 6000 m over the oven directly towards the coastline. At a fertile time , the angle of depression to the coastline from the airplane is 14 degrees. How much further does the airplane have to fly before it’s directly about coastline?

is called echinoderms

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
