Ecology: The scientific study of interactions among organisms and between organisms and their environment, focusing on distribution, abundance, and relationships.
Biodiversity: The variety and variability of life forms within a given habitat or ecosystem, including species richness and genetic diversity.
Ecosystem: A biological community of interacting organisms and their physical environment, functioning as a unit with energy flow and nutrient cycling.
Ecosystem Services: Benefits humans obtain from ecosystems, such as food, water purification, climate regulation, and recreation.
Trophic Levels: The hierarchical levels in a food chain, representing organisms' positions based on their source of energy (producers, consumers).
Nutrient Cycling: The movement and exchange of organic and inorganic matter back into the production of living matter, involving processes like the carbon, nitrogen, and phosphorus cycles.
