Chapter 21.8, Problem 1CR
Summary Introduction
Microorganisms are responsible for the breakdown of organic matter and some also contribute in releasing greenhouse gases. Various activities of microbes lead to global climate change and also minimize emission of various gases. It has been observed that microbial processes play a central role in regulating global fluxes of greenhouse gases and rapidly respond to climate changes.

Matter is continually recycled between abiotic and biotic components of Earth's ecosystem in biogeochemical cycles. the various cycles differ from one another in several key aspects of their storage, conversion and modes of transport.
In cognizance, describe and explain ONE way in which humans have disrupted the natural cycling of carbon and TWO major environmental consequences of that disruption. For 3-5 sentences only
Altered biogeochemical cycles combined with climate change increase the vulnerability of biodiversity, food security, human health, and water quality to a changing climate.

Read the sections in the textbook and refer to the diagrams for each of the cycles.These cycles are constantly going on around us. Think about how we are involved in these cycles. What parts of the major biogeochemical cycles do we witness or experience in our daily lives? Give one example per post or response. Think about where the element or nutrient may have come from or where it may go next and whether the process may have been affected by humans and human activities.A simple example (using the hydrologic cycle, which we studied in Chapter 7): Yesterday I was at the beach and witnessed rain falling into the ocean.

Some researchers have hypothesized that the feedback loop pictured below influences the carbon dynamics of Arctic ecosystems as follows: Elevated atmospheric CO₂ levels cause the climate to warm, thawing permafrost. Nitrogen mineralization is then stimulated as thawed permafrost decomposes. The resulting increase in soil ammonium then stimulates primary production, which pulls CO₂ from the air.
