Final answer:
Phenotypic plasticity allows organisms to change their phenotype in response to environmental changes. However, not all organisms are phenotypically plastic. Organisms that are not exhibiting phenotypic plasticity are unable to adapt their phenotype to new environmental conditions.
Step-by-step explanation:
Phenotypic plasticity is the ability of an organism to change its phenotype in response to environmental changes. However, not all organisms are phenotypically plastic.
In this case, the organisms that are not exhibiting phenotypic plasticity are:
A chipmunk species in a forest with only one predator begins to decline when a new predator is introduced.
A frog that moves from a pond with consistently warm water to a pond with colder water and fails to reproduce.
A plant species in a temperate environment withers and dies during short periods of drought.
These organisms are unable to adapt their phenotype to the new environmental conditions, which results in negative consequences for their survival or reproduction.
