<h3>What is biomass?</h3>
- Renewable organic material obtained from plant and animal sources if referred to as biomass.
- Primary productivity is the production of organic compounds through the process of photosynthesis, with the help of solar energy.
- Primary productivity is measured as biomass produced per unit area over a give time period
- It is usually expressed either in weight or energy.
- There are two ways to express primary productivity:
a) Gross Primary Productivity(GPP): Takes into account the total energy produced in the ecosystem.
b) Net primary Productivity(NPP): Takes into account, solely the energy used by the producer for respiration.
