Organisms exhibit different types of adaptations as a means of survival. what type of adaptations do the caterpillar and the plant show in this interaction? the green color of the caterpillar is an example of a adaptation to avoid predators, while the release of bioactive chemicals by the plant to protect itself from the insects attack is a adaptation.

The green color of the caterpillar is an example of a structural adaptation to avoid predators, while the release of bioactive chemicals by the plant to protect itself from the insects attack is a physiological adaptation.

Adaptation is a change or multiple changes occurs in an organism to facilitate it's survival in the environment it is living. The green color of the caterpillar is an example of a structural adaptation. Structural adaptations are changes in the physical features of the organism which help it to survive in it's natural habitat. The green of caterpillar mimic that of a grass therefore, caterpillar remains undetected by predators like birds. The release of bioactive chemicals by the plant to protect itself from the insects attack is a physiological adaptation.  Physiological adaptations are internal metabolic  physiological responses generated in an organism against external stimulus in order to increase it's chances of survival. The release of bioactive chemicals is the result of metabolic processes taking place in a plant in order to kill the insects and increase chances of own survival.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
