At the beginning of the spring, Dr. Alice Whittlesby notices that there is an equal distribution oflong and short stemmed buttercups in the vacant lot across the street from her house as well asin her own backward. By the end of the summer she notes that there are mostly long stemmedbuttercups in the lot, but mostly short stemmed buttercups in her yard. These observations areexamples of what biological principle? Develop a hypothesis to explain Dr. Whittlesby’sobservations.2.)Consider the food web for Lake Erie shown above.Give a detailed analysis of this food web. Be sure to address the following in your analysis:1.a description of the producers and consumers (you do not need to list every organism, but give a fewexamples along with what makes an organism fall into one class or the other)2.energy movement through the food web3.the number of trophic levels found in this food web4.which organisms most efficiently utilize the resources5.the way in which of one biogeochemical cycles interacts with the ecosystem of this food web6.how humans can negatively impact this food web3.)
