Living organisms and non-living elements form ecosystems, with biotic and abiotic factors shaping habitats.
Living beings, including plants and animals, are termed organisms, each playing a unique role in ecosystems.
Groups of the same species constitute populations, exhibiting interactions and behaviors within their habitat.
Populations of various species coexist in communities, sharing geographic areas and ecological resources.
Natural selection drives organisms to adapt to their environment, evolving behaviors and physical traits for survival.
Organisms interact through competition, predation, and symbiotic relationships, shaping ecosystem dynamics and biodiversity.
