Producers, like this plant, take in oxygen and release carbon dioxide during , just like animals and other living things

During the process of cellular respiration, the cells use oxygen and give up carbon dioxide as their by product.

Some plants also take in oxygen and release carbon dioxide during the process of cellular respiration. The cellular respiration in the plant is similar to the cellular respiration, which occur in animals.

Hence, the given blank can be filled with cellular respiration.

the answer is d (apex) good luck : ))

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
