Answer:
A coral reef is a reef-shaped structure in the sea, formed by anemones and which over time becomes large enough to have a significant ecological and physical impact on its environment. These are the largest structures built from living organisms in the world. Coral reefs are complex marine ecosystems. They are a biotope (area of life) of a biocenosis (community of living beings) consisting of plants and animals, for example worms, shellfish, sponges, thorns and crustaceans. Coral reefs play a significant role as “breeding grounds” for the offspring of fish inhabiting the high seas.

An explosion occurs when the timescale for the energy release by some process is much shorter than the timescale on which a system can adjust to damp the energy release process. In the present day Sun, nuclear fusion is a very slow process: on average it takes many billion years for a proton to fuse with another. This timescale is quite temperature dependent, so you might have thought the centre of the Sun might heat up quickly, leading to a runaway "explosion". However, an increase in temperature leads to an increase in pressure that would expand the Sun, reducing the core density and temperature and decreasing the rate of nuclear fusion again. The timescale for the Sun to react in this way is just millions of years, so this acts like a thermostat that keeps the reactions under control.
