Question Description
each q going to be 1-2 paragraphs
only referance to use is the book which i will provide as soon as you reply
Question 1
Why do some species demonstrate seasonal dimorphism? What environmental triggers stimulate these physical changes? What physiological processes might play a role in these physical changes?
Question 2
When faced with limited resources, how do individual organisms respond in terms of allocation of those resources? Provide an example and include how allocation of limited resources affects evolutionary fitness (survival and reproduction).
Question 3
Which structure in the human body is responsible for filtration? Why are the physiological processes of this structure important for survival?
Question 4
Peppered moths responded to environmental change (namely pollution) by shifting their morphology to a darker color. Why was this change in color morph important to the survival of these populations? Explain how this change is expressed at the population level, rather than the individual level. (Hint: think in terms of adaptation and evolution).
Question 5
How did the role of humans as predators likely impact populations of prey species? Provide relevant examples.
Question 6
What is biomagnification? How were raptor species (e.g., peregrine, American kestrel) affected by biomagnification of the insecticide, DDT?
Question 7
What is a dead zone? How does a dead zone form? What are the ecological consequences of a dead zone?
Question 8
Choose one of the ecosystems (e.g., montane, arctic tundra, tropical rainforest, etc.) that we discussed in lecture. Provide a description of the ecosystem services (with more detail than is in the slide). How can we manage this ecosystem’s homeostasis? What measures of management and conservation should be taken?
Question 9
What is the Tragedy of the Commons? Provide an example of how this economic theory applies to ecology and ecological homeostasis. Include any relevant details to support your answer.
