3. An asteroid over 100 meters in diameter could affect an entire country. Scientists predict that there is a 1% chance that an asteroid of this size could strike Earth in
the next 100 years. What factors could cause the calculation of this probability to
increase or decrease?

a

explanation:

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
