If two organisms belong to the same family, what other taxonomic groups do the organisms have in common?

All of the groups above or higher than the family... kingdom, phylum, class, and order.

Hope I helped! ( Smiles )

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.
