Explanation:
Coal is a fossil fuel formed over millions of years and is finite, thus non-renewable. Solar, wind, and tidal energy are renewable and replenishable. Non-renewable resources include coal, petroleum, natural gas, and nuclear minerals. Overexploitation leads to depletion and environmental pollution. Conservation of such resources is essential for sustainable development.

Explanation:
Azotobacter is a free-living, aerobic, nitrogen-fixing soil bacterium used as a biofertilizer for non-legume crops like wheat, maize, and cotton. Rhizobium is symbiotic, Nostoc is a cyanobacterium (algal biofertilizer), and mycorrhiza is a fungal symbiont that enhances phosphorus uptake. Biofertilizers reduce the need for chemical nitrogen fertilizers and are eco-friendly.
