Final answer:
Plants can be harmed by growing in a greenhouse with stable conditions because the lack of seasonal cues affects critical plant processes and limits the efficient use of resources.
Step-by-step explanation:
Growing certain plants in a greenhouse with stable light, humidity, and temperature can harm the organism because the stable conditions in the greenhouse can disrupt critical plant processes that rely on seasonal cues. For example, plants use seasonal cues like the length of daylight to regulate their growth, flowering, and dormancy periods. Without these cues, plants may become stressed or fail to properly complete these processes. Additionally, lack of fluctuations in temperature and humidity can limit the efficient use of resources like water and carbon dioxide, which can impact plant metabolism and growth.
