¿Qué es un ecosistema?

Ecosystems are communities of organisms interacting with their environment, varying in size from ponds to forests. On a larger scale, biomes are defined by vegetation and climate, with biodiversity being the variety of species within them. Ecosystems consist of abiotic (non-living) and biotic (living) factors that interact continuously. Organisms occupy specific niches, contributing to ecosystem stability and balance.
