The biosphere is the parts of the Earth where living organisms are. The Bay, all that inhabit it and its surrounding watershed are all components of the biosphere. The same is true for the life in forests, birds in the air and the people living in cities and on farms. Life on earth is both adaptive and resilient and has evolved to tolerate habitation in all of the Earth’s systems.
Carbon is the chemical backbone of life on Earth and is a key element in many important environmental processes. Carbon helps to regulate the Earth’s temperature and make the food that sustains us.
Most of Earth’s carbon is stored in rocks and sediments, while the rest is located in the ocean, atmosphere and living organisms - these are the channels through which carbon cycles. The movement of carbon through the food chain is an example of the carbon cycle; plants remove carbon from the atmosphere and add it to the biosphere through photosynthesis. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle.
