Photosynthesis is the process by which green plants convert sunlight into chemical energy, storing it in glucose molecules. This mechanism not only fuels plant growth but also releases oxygen into the atmosphere, supporting nearly every living organism on Earth.

Genetic mutations arise through random errors during cell division. While most mutations are harmless or even detrimental, a small percentage may confer a survival advantage, gradually driving the evolution of species when favoured by natural selection over many generations.

Coral reefs support roughly one quarter of all marine species despite covering less than one per cent of the ocean floor. Scientists warn that rising water temperatures and increasing acidity threaten to destroy these fragile ecosystems within decades if current trends continue.
