Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary microbial process?Methanogenesis, carried out by archaea in anaerobic conditions
2. What is the key chemical formula?Methane (CH4)
3. What is marsh gas and why does it smell funny?Marsh gas is mainly methane produced by tiny microbes in swamp mud. It smells funny because of gases like hydrogen sulfide and trace phosphine.
4. How do microbes make methane in swamps?Microbes called methanogens break down dead plants and animals in low‑oxygen mud. They use two main pathways: turning acetate into methane or using CO2 and hydrogen to make methane.

Methanogenesis: The biological production of methane by microorganisms under anaerobic conditions.
Aerenchyma: Specialized plant tissues that facilitate gas transport between roots and shoots.
Biogeochemical Cycle: The pathways by which chemical elements and compounds move through both biotic and abiotic components of ecosystems.
