To explain: The reason that consumption of a large amount of carbon dioxide by living trees does not make much contribution in the reduction of global warming.
Concept introduction:
The earth’s surface has enormous amount of carbon. It moves through the biosphere in the processes mediated by photosynthetic plants on land and in sea. This is represented as the carbon cycle, which involves two main processes namely photosynthesis and respiration. The photosynthesis process involves fixation of atmospheric carbon in plants to form organic molecules such as sugars required for life processes. Respiration is the process through which carbon is returned to the atmosphere from dead plants in the form of carbon dioxide.

- PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.arrow_forwardOther than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)?

You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forward
