Answer: biomass energy
Step-by-step explanation:
A renewable resource is the one which is abundantly available in nature. It can be replenished after a single use. For example sunlight, water, forests. A non renewable resource is the one which cannot be replenished after once used. For example fossil fuels.
Biomass energy is an energy which is obtained by burning a carbon mass which is likely to obtain from a natural source like plants : wood, or bio oil produce from animals and plants. Although it is a renewable energy source as plants and animals can be reared for availing the energy. But this energy is required to be conserved and prevented from overuse unless it becomes a non-renewable resource. As it may lead to extinction of some plants or animal species which are the source of energy.
