An ecological network is a system of interconnected organisms and their environments, illustrating how different species interact with one another and their habitats. These networks include various relationships, such as predator-prey dynamics, competition, and symbiosis, which help maintain ecosystem balance and biodiversity. Ecological networks can be visualized through food webs, which show how energy and nutrients flow between species. They are essential for understanding ecosystem health and resilience, as disruptions in these networks can lead to declines in species populations and overall ecosystem function. Conservation efforts often focus on preserving these networks to ensure ecological stability.
