Question
Chapter 56.4, Problem 2CC
Summary Introduction
To understand: The reason behind scientists who study global warming are monitoring the carbon reservoirs.
Introduction: Global warming can be defined as the heating of the earth’s surface and the increased temperature of the atmosphere. It is caused by greenhouse gases. Nowadays greenhouse gases are increasing due to various human activities like burning fossil fuels, deforestation etc, which are affecting the ozone layer of the earth.

Background:
One of the main drivers of climate change is the emissions of carbon dioxide gas into the atmosphere from the burning of fossil fuels. This has altered the global carbon cycle. using the link below to watch https://youtu.be/xk11DVaAjEA
PROMPT:
1) What role does photosynthesis paly in the global carbon cycle?
2) What are fossil fuels and how are they altering the global carbon cycle?
3. Learn about carbon sequestration. Briefly explain what it is and how it can help to mitigate the impacts of climate change. Post a link an example of where/how this is being implemented.

Create a model which accurately, in detail, depicts the potential pathways of carbon (biomass) and energy in an ecosystem with at least five trophic levels (don’t forget your decomposers, they can count as one trophic level). Make sure to incorporate the multiple pathways that biomass and energy could take at each trophic level. Lastly, clearly illustrate how carbon and energy flow in this ecosystem.
