The three methods by which we can reduce the problem of waste disposal are :(i) Adopting the $5\ \mathrm{R}$ approach i.e;-Reduce, Reuse, Recycle, Refuse and Repurpose.(ii) Segregation of waste into biodegradable and non-biodegradable waste.(iii) Conversion of waste into useful components like biogas and then using compost as a fertiliser. BALOREcosystem refers to the interaction of all the biotic and abiotic components present in a particular area. Energy flows across the trophic levels following the $10\%$ law. Only $10\%$ of the energy available to a trophic level is passed on to the next trophic level.(i) For example $10,000\ \mathrm{J}$ energy is available to producer.(ii) Then $1000\ \mathrm{J}$ energy will be available to primary consumer.(iii) $100\ \mathrm{J}$ energy will be available to secondary consumer.(iv) $10\ \mathrm{J}$ energy will be available to tertiary consumers.
