Lecture on the Biosphere
Subject: Geography | Topics:

The biosphere is the “life zone” of the Earth, and includes all living organisms (including humans), and all organic matter that has not yet decomposed. The biosphere is structured into a hierarchy known as the food chain (all life is dependant on the first tier – mainly the primary producers that are capable of photosynthesis). Energy and mass is transferred from one level of the food chain to the next.
