An ecosystem is a community of living organisms (plants, animals, and microbes) interacting with each other and their physical environment (soil, water, air). These interactions create a balanced system where energy and nutrients are constantly exchanged. A biome, on the other hand, is a large geographic area characterized by specific climate conditions, animal populations, and plant species. Think of biomes as massive ecosystems encompassing vast regions, such as deserts, rainforests, or grasslands. Understanding ecosystems and biomes helps us see how everything is connected and how crucial it is to protect them!
