The physical characteristics of an organism are its

appearance, development, and behavior

Explanation:

The phenotype, similar to the genotype, can be observed in two senses: wider and narrower. In a broader sense, a phenotype is a set of all morphological and physiological properties by which an organism is recognized and by which it differs from other organisms.

When we look at only one trait, then it is the narrower meaning of the phenotype. What will be the influence of genotype on phenotype depends not only on the genetic basis but also on the action of environmental factors in which the organism develops.

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.
