Question
Given the information in the graph what conclusion can you make with respect to the relationship between climate change (increasing global temperatures) and the amount of carbon dioxide released into the atmosphere by land ecosystems? Explain, using information from the graph to support your explanation.
18°C 28°C CORN PHOTOSYNTHESIS RESPIRATION TEMPERATURE Right now, about 10% of ecosystems reach that tipping point for at least a little while every year. If there is no change in carbon emissions and global temperatures increase as expected then by the year 2100 more than half of all land ecosystems could be past that tipping point. The Amazon rainforest and the Taiga of Russia and Canada account for approximately 40 - 70% of the carbon pulled from the atmosphere by ecosystems on land. This means that the global tipping point when land plants put more carbon dioxide in the atmosphere than they take in will occur around 2040. It's possible that plants can adapt and the rate of photosynthesis could increase with increasing temperatures but scientjsts don't think that 20 years is enough time. Other studies have found that oceans may be getting better at absorbing carbon dioxide due to a decrease in churning up of the ocean water. Oceans currently absorb 40% of the Earth's carbon dioxide. The best way to help is doing what we can to reduce carbon emissions. ENZYME ACTIVITY PHOTOSYNTHESIS

Ecosystems and Climate Change Ecosystems on land currently absorb about 1/3 of humnan-made carbon emissions. This helps to reduce the effects of climate change. However, recent research suggests that land ecosystems could accelerate climate change. Plant cells undergo photosynthesis but they also undergo cellular respiration. How fast photosynthesis and cellular respiration happen is dependent on temperature. Photosynthesis and cellular respiration don't speed up or slow down at the same rate. The balance between removing carbon dioxide from the atmosphere and adding carbon dioxide to the atmosphere is important in the battle over climate change. Research was recently done to investigate how the rates of photosynthesis and cellular respiration might change as global temperatures change. The researchers gathered information from carbon monitoring stations around the world. These stations monitor local daily temperatures and how much carbon was exchanged between the atmosphere and the Earth. Using this information the researchers were able to map changing photosynthesis and respiration rates to temperature, locally and globally. Below is a graph showing Enzyme Activity vs Temperature for photosynthesis by trees, rice, and wheat (green line), sugarcane and corn (yellow line) and for plant cellular respiration. The optimal temperatures for photosynthesis and cellular respiration are also recorded on the graph. The tipping point in ecosystems for the balance between photosynthesis and cellular respiration occurs when there is more cellular respiration occurring than photosynthesis.
