A green economy is defined as low carbon, resource efficient and socially inclusive. In a green economy, growth in employment and income are driven by public and private investment into such economic activities, infrastructure and assets that allow reduced carbon emissions and pollution, enhanced energy and resource efficiency, and prevention of the loss of biodiversity and ecosystem services.

Respiration

The chemical breakdown of organic food substances such as glucose in the living cells to release energy with or without molecular oxygen.

Burning

Combustion, or burning,is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

Decomposition

The process or effect of simplifying a single chemical entity into two or more fragments.

Photosynthesis
