Because that's where the solar rays hit the earth at a 90 degree angle. And the earths rotation on a tilt causes the Solstice and Equinox.
Because over a long period of time, the sun appears to wiggle back and forth, north and south, between the Tropic of Cancer (23 degrees north latitude) and the Tropic of Capricorn (23 degrees south latitude), making a complete wiggle in one year. In the course of that process, it crosses the equator twice, and when it does, the equator experiences maximum solar radiation. Actually, when you think about it, EVERY spot on Earth that's anywhere between the Tropics of Cancer and Capricorn receives two peaks of solar radiation during a year.
Solar maximum can occur up to 42 degrees north of the equator as it did in 1859.
NPP decreases from the equator to the poles as a result of the amount of solar radiation available. Therefore, NPP is more at the equator.
Equator has a lower angular deflection of sunlight and therefore warmer temperatures

the equator
The north pole receives more solar radiation during the summer than the equator does, but during winter, it receives no solar radiation. This means that as latitude increases, the amount of solar radiation increases in the summer and decreases in the winter.
Visible light radiation
NPP decreases from the equator to the poles as a result of the amount of solar radiation available. Therefore, NPP is more at the equator.

!WRONG!infrared radiation!CORRECT AWNSER!visible light radiation
Rain forests are so hot because they are found near the equator. The closer to the equator you are, the more solar radiation there is. The more solar radiation there is, the hotter it is.
