Answer:

Carbon dioxide, methane, nitrous oxide

Answer 2

Greenhouse gas

• Some greenhouse gases occur naturally and enter the atmosphere as a result of both natural processes (such as decomposition of organic matter) and human activity (such as burning fossile fuels and agriculture).
• Greenhouse gases that occur both naturally and from human activities include water vapour, carbon dioxide(CO)2, methane(CH4), nitrous oxide(N2O) and ozone(O3).
• Other greenhouse gases have essentially no natural sources, but are side products of industrial  processes or manufactured for human processes such as cleaning agents, refrigerants, and electrical insulators.
