A natural disaster can cause an ecosystem to obliterate completely.
On March 18th, 1980, Mount St. Helens erupted in Washington. The eruption caused over 19 miles of destruction. Nearly 40 years later, the surrounding area still showed signs of recovering. The hot blast of volcanic ash destroyed the ecosystem around the volcano, and while the ecosystem was destroyed, eventually the ecosystem slowly grew back to flourishing.
Explanation:
As Earth cooled, an atmosphere formed mainly from gases spewed from volcanoes. It included hydrogen sulfide, methane, and ten to 200 times as much carbon dioxide as today's atmosphere. After about half a billion years, Earth's surface cooled and solidified enough for water to collect on it.
Oxygen plays a critical role in respiration, the energy-producing chemistry that drives the metabolisms of most living things. We humans, along with many other creatures, need oxygen in the air we breathe to stay alive. Oxygen is generated during photosynthesis by plants and many types of microbes.
