All organisms interact with their environment. choose one of the biogeochemical cycles and explain how various types of organisms are part of that cycle and recycle the substance in an ecosystem. provide one example of how human activity has impacted the cycle you have chosen and one step we can take to reduce human impact on the ecosystem.

The water cycle affects all living things. Humans have polluted the water making it unsafe and in some cases not suitable to support life.

The chosen cycle is carbon cycle

How organisms are part of cycle?

Carbon is one of the main elements of organic matter constituting living beings. It is the plants that fix it during their growth, from the CO2 present in dissolved form in the oceans or in gaseous form in the atmosphere. It is then either released into the air or water by respiration, or sequestered more or less long in the soil and seabed. The carbon cycle plays a decisive role in the greenhouse effect, whether natural or not, given its influence on the concentration of CO2 present in gaseous form in the atmosphere.

How does the activity impact the cycle?

Carbon dioxide and methane alone account for ¾ of the problem of global warming. Indeed, the arrival of industry has turned the cycle upside down, it has caused a sharp increase in the concentration of greenhouse gases in the atmosphere that has amplified the greenhouse effect and global warming.

In April 2014, CO2 concentrations reached 400 ppm throughout the northern hemisphere, bringing us closer and closer to the 450 ppm considered dangerous for the planet's climatic equilibrium.

The step we can take to reduce the impact:

Man must react, if we do not remedy this increase in CO2 emissions, melting ice could cause an increase in ocean level of about 70 meters. To avoid this, a goal has been launched, it would reduce our CO2 emissions by 4. But for this it should first of all that men become aware of its responsibility in global warming if we want to hope that there is change.

Man has a great responsibility in global warming that could have a lot of damage on the planet. Showing the importance of the carbon cycle helps prevent future hazards.

the answer would be d : p
