What does the biosphere include?

The biosphere encompasses all regions of Earth that support life, which includes not only land areas but also the water and air. It represents the sum of all ecosystems and is where organisms interact with each other and their environment, including the soil, water bodies, and atmosphere. This definition highlights the interconnectivity of various ecosystems, showing that life exists in diverse forms across different habitats, such as forests, oceans, and deserts.

By recognizing that the biosphere includes both terrestrial (land) and aquatic (water) environments, as well as the atmosphere that allows for gaseous exchanges necessary for life, we gain a more comprehensive understanding of how biological systems function and rely on one another. This understanding is crucial for studies related to ecology, environmental science, and conservation efforts.
