Are spore numbers higher before dispersal or after dispersal? explain

Before because, there are many things that can render a spore useless, like if it lands in water or if it is inhaled by an animal.

Well, both latitude and intensity of light affect temperature because, the higher the light intensity, the higher the temperature and since latitude is the measure of how close you are to the equator, then the closer to the equator you are, the higher the temperature is.
