Why don't we get an eclipse every month? *

ANSWER:

We don't get an eclipse all period because the Moon's revolution is turned at  approximately 5∘ to the ecliptic.

EXPLANATION:

If the Moon's revolution was in the equal level as the Earth's we would encounter two  eclipses all period. A solar eclipse would appear every new moon also a lunar eclipse  would appear every full moon. As the Moon's orbit is turned at 5∘ to the ecliptic, an  eclipse can simply happen when the Moon is near one of its links which are the points  where the Earth and Moon circles intersect. The line joining the links also has to be  facing towards the Sun.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
