Individual ants of the same species use pheromone trails to indicate the path to different food sources or back to their own colony. This is an example of ~growth and response

~genotype mutation

~inclusive fitness

~phenotypic plasticity

D. Phenotypic Plasticity

Explanation:

I just took the quiz and this was the correct answer.

Phenotypic plasticity simply refers to the changes in an organism's behavior, morphology and physiology in response to a unique environment. Phenotypes aren't always something visual, and in this case its the ant's pheromones that are being used ("changed") in order to aid its travels to and from food sources and ensure that it does not get lost.

This was my thought process as I figured out the question so hopefully it makes sense!!

a. decomposes use carbon from dead organisms as fuel for cellular respiration, returning carbon dioxide back into the atmosphere.
