Answer:
There is about 6000 satellites surrounding our earth. A satellite orbits Earth when its speed is balanced by the pull of Earth's gravity. Without this balance, the satellite would fly in a straight line off into space or fall back to Earth. Satellites orbit Earth at different heights, different speeds and along different paths.

If you take the frog out of the food chain, a food chain imbalance will occur. For instance, the prey on which the frog feeds on, lets say flies, increases dramatically, which causes problems for the other animals in the food chain.
The predator of the frog will also decrease in number due to the loss of their food source.
<h2><u>
Air particles at different layers of the atmosphere</u></h2>
Earth's atmosphere has four layers namely Troposphere, Stratosphere , Mesosphere and Thermosphere where troposphere is nearest to the earth and thermosphere is farthest and temperature increases with increase in altitude of the layer of atmosphere. So, temperature is highest in thermosphere and lowest in troposphere. so the ascending order of temperature is Troposphere < Stratosphere < Mesosphere < Thermosphere.
Dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and a small amounts of some other gases by volume. It also contains a varied amount of water vapor, around 1% at sea level, on average and 0.4% over the entire atmosphere.
