Does banyan tree exhales co2 in the day?

Yes, banyan trees, like all plants, undergo photosynthesis during the day, which allows them to absorb carbon dioxide (CO2) and release oxygen (O2). However, they also engage in respiration, a process that occurs both day and night, whereby they take in oxygen and release CO2. While the net effect during the day is a reduction in atmospheric CO2 due to photosynthesis, they still exhale some CO2 as a byproduct of respiration. Thus, they do exhale CO2 during the day, but the overall impact is beneficial for the environment.
