Question

question 8 of 13
select the statement that describes how an organism’s fitness level and environment relate to one another.
the more suitable an environment is for an organism’s phenotype, the higher the organism’s fitness level.
the less suitable an environment is for an organism’s phenotype, the higher the organism’s fitness level.
the suitability of an environment for an organism’s phenotype has no relation to the organism’s fitness level.
an organism with a particular fitness level in one environment has the same fitness level in every environment.
the more suitable an environment is for an organism’s phenotype, the lower the organism’s fitness level.

Explanation:

Fitness in biology refers to an organism's ability to survive and reproduce. A phenotype suitable for an environment improves survival/reproduction chances, increasing fitness. Thus, greater environmental suitability for an organism’s phenotype correlates with higher fitness. Other options contradict this core biological concept.

Answer:

The more suitable an environment is for an organism’s phenotype, the higher the organism’s fitness level.
