Why do meteors light up in the atmosphere?

When a meteoroid enters the Earth's upper atmosphere, it heats up due to friction from the air. The heat causes gases around the meteoroid to glow brightly.

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
