Ecological networks are complex systems of interactions between different species in an ecosystem. These interactions can include predator-prey relationships, competition for resources, and mutualistic partnerships. By studying these networks, researchers aim to understand the structure, dynamics, and functioning of ecosystems, as well as how they are influenced by factors such as climate change, habitat loss, and invasive species. Ecological networks can provide valuable insights into the stability and resilience of ecosystems, as well as inform conservation efforts and biodiversity management strategies.
