Coevolution
Explanation:
Coevolution is the phenomena in which two interacting species evolve under the influence of each other.
Global warming caused a drastic rise in temperature. The temperature condition during the original flowering season became higher than the optimum flowering temperature. So, the flowering plants began to flower earlier.
This created a food crisis for bees who were adapted to collect food during the flowering season. However, they evolved along with the flowering plants and started searching food earlier.
So we can say that evolution of flowering plant caused the evolution of bees.So it is a coevolution.
One very common function of an antenna of an arthropod would be for sensory. It is used by these organisms mainly for touch. Also, other uses would be sensing the motion of air, heat, sound and as well as taste and smell.
