Los fundamentos de la ecología: ecosistema

The video tutorial compares desert and swamp ecosystems, highlighting their differences in moisture levels and the distinct plants and animals found in each. It introduces the concept of ecosystems, which include both living (biotic) and non-living (abiotic) components. Biotic factors consist of visible organisms like plants and animals, as well as microorganisms. Abiotic factors include elements like sunlight, precipitation, temperature, soil type, wind, and water, all of which influence the ecosystem's living components.
