As explained in the pages earlier, ecosystems include more than a community of living organisms (abiotic) interacting with the environment (abiotic). 

Biome: 

A biome, in simple terms, is a set of ecosystems sharing similar characteristics with their abiotic factors adapted to their environments.

Biosphere: 

When we consider all the different biomes, each blending into the other, will all humans living in many different geographic areas, we form a huge community of humans, animals and plants, in their defined habitats.
