The correct answer is ‘Study of periodical phenomena of plants, such as the time of flowering in relation to climate’.
Phenology is the study of cyclic and seasonal natural phenomena, especially in relation to climate and plant and animal life. It focuses on the timing of recurring biological events, such as flowering, leaf unfolding, migration, and breeding, and their correlation with environmental factors like temperature, precipitation, and photoperiod.
Phenological studies are crucial for understanding the impacts of climate change on ecosystems. Changes in temperature and other climatic factors can alter the timing of phenological events, potentially leading to mismatches between interacting species (e.g., plants and their pollinators or herbivores) and disrupting ecosystem dynamics.
