Ecosystems and biomes are related concepts in ecology, but they are not the same thing.
An ecosystem refers to a community of living organisms interacting with each other and their physical environment. It includes all the living (biotic) and non-living (abiotic) components in a specific area, such as plants, animals, soil, water, and sunlight. Ecosystems can be large or small and can exist within a biome.
On the other hand, a biome is a large geographical area with similar climate, geography, and vegetation. Biomes are characterized by distinct plant and animal communities that have adapted to the specific environmental conditions of that region. Examples of biomes include deserts, tropical rainforests, grasslands, and tundras.
In summary, ecosystems refer to the interactions between living organisms and their environment in a specific area, while biomes are larger regions with similar characteristics that encompass multiple ecosystems.
