Songbirds often eat berries. berry seeds are activated by the acids located in a bird's stomach. once the bird's body eliminates the berry seeds as waste, they often fall to the ground and begin to grow. this an example of the songbird's: population community habitat niche

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

the answer is a. at the equator
