The carbon cycle is an important process that helps move carbon around our planet. This movement affects our climate and the different kinds of life on Earth. Carbon can be found in several forms, including carbon dioxide (CO₂), organic materials, and stones called carbonate rocks. All of these parts work together in a big system.
Photosynthesis: Every year, plants take in about 120 billion metric tonnes of carbon through a process called photosynthesis. They change CO₂ into organic material, which is essential for the food chain.
Respiration: Living things, including animals and humans, breathe out about 100 billion metric tonnes of carbon back into the air. This is important because it helps keep a balance with what plants take in.
Decomposition: When plants and animals die, decomposers like fungi and bacteria break them down. This process adds around 70 billion metric tonnes of carbon back into the soil and air each year. This helps give important nutrients back to the environment.
Combustion: Human activities, especially burning fossil fuels and cutting down forests, release about 36 billion metric tonnes of CO₂ every year. This makes the levels of carbon in the atmosphere go up.
Greenhouse Effect: Higher levels of CO₂ create the greenhouse effect, which traps heat in the atmosphere. Since the late 1800s, the average temperature across the globe has risen by about 1.1°C due to carbon emissions from human activities.
Ocean Acidification: About 30% of the CO₂ in the air has been absorbed by oceans. This has lowered the pH of ocean water by about 0.1 units since the start of the Industrial Revolution. This change can harm marine life and reduce biodiversity.
As the climate changes, plants and animals face new challenges that can lead to their extinction. Here are some important points:
Extinction Rates: Right now, the rate of extinction is estimated to be 100 to 1,000 times higher than normal because of climate change and losing habitats.
Habitat Disruption: Warmer temperatures and different rain patterns can change habitats. This forces species to move to new areas or adapt, which can hurt biodiversity. For example, it is believed that if global temperatures rise more than 2°C, up to 30% of species may be at risk of going extinct.
In conclusion, the carbon cycle is essential for regulating Earth's climate and keeping various life forms alive. Understanding this cycle is important for finding ways to fight climate change and help protect the many kinds of life we have on Earth.
