Studying the role of primary producers in ecosystems is significant because they form the base of the food web. Primary producers, such as plants and phytoplankton, convert sunlight into energy through photosynthesis, supporting all other trophic levels, including herbivores and carnivores. Their health and abundance influence biodiversity, nutrient cycling, and overall ecosystem functioning. Understanding their dynamics helps inform conservation strategies and resource management practices. Moreover, primary producers play a critical role in mitigating climate change by absorbing carbon dioxide, thus maintaining ecological balance and promoting sustainability.
