- 1. Forest ecology is the study of the interrelationships between the organisms within forest environments and their physical and biological surroundings. It explores how forests function as ecosystems, including the diversity of plant and animal species, the distribution of nutrients, energy flow, and ecological processes such as photosynthesis, decomposition, and nutrient cycling. Forest ecology also investigates the impact of human activities on forest ecosystems, such as deforestation, logging, climate change, and pollution, and aims to develop strategies for sustainable management and conservation of forest resources.
