Which statement about organism classified in the same genus is true?

The correct answer is - They must be in the same phylum but may be a different species.

Explanation:

Genus is a taxanomic category in a biological classification that is more inclusive than phylum and class and ranks above the species. It includes the group of organism that are under in same family, class, or phylum in more general but these organism may belong to different species.

Thus, the correct answer is -  They must be in the same phylum but may be a different species.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

the darker peppered moth species were favored due to the fact that the industrial revolution had made all the nearby trees a darker color instead of white.
