In comparing these two species, photosynthesis increases more rapidly in the presence of carbon dioxide for plants. The C4 species reaches a peak rate of photosynthesis at and the C3 species reaches a peak rate of photosynthesis at . This means that carbon dioxide concentrations in excess of will not increase the rate of plant growth or carbohydrate production for either species. The tropical C4 species grows more quickly. Since the photosynthesis reaction requires an equal number of CO2 and , this is adaptive for tropical environments.
The graph shows the amount of rain that California has received over the past 40 years. Based on this data, predict how changes in rainfall in 2014 would impact organisms in the state.
The precipitation in 2014 was normal. Because organisms in the state are adapted to live in an environment with approximately inches of rain a year, rain conditions in 2014 would probably the chance these organisms will survive.
A carbon atom moves between many different reservoirs as it moves through the carbon cycle. Starting with a molecule of carbon dioxide gas, place these different reservoirs in the order in which carbon would flow through them.
1) Carbon can enter the atmosphere and hydrosphere through burning of fossil fuels and volcanic activity. Weathering of limestone also releases carbon into the atmosphere.
2) Carbon dioxide is pulled out of the atmosphere by plants to be used during . Through this process, the carbon is stored in the plant as .
3) Plants and animals use the stored carbon during to produce energy. A byproduct of this process is which is released back into the atmosphere.
4) When organisms carbon is again released into the atmosphere by microorganisms. During this process, carbon is also stored in rocks, such as limestone or coal.
Nitrogen gas can be used directly from the atmosphere by the plants in our ecosystem.
