If you are a biologist interested in working(a) in the tropical rainforests, briefly describe a research study you could complete at all(prenominal) train in the biological hierarchy, starting from the organisms level to the biosphere. 2. What are the two biotic variables that dictate eccentric of terrestrial bimbo? Do aquatic and marine systems rely on the same two variables? Why or why not? 3. Which of the terrestrial boomers Is the most vulnerable to anthropogenic (human) Influence and why?What Is being unnatural? 4. Create a table that lists the bimbo, biotic variables that are elevate, and examples of organisms that would reside there. 5. Why arena species all all over the planet? What influences dispersal? 6. What is the value of describing populations using density, dispersion, and demographic information? Be particular and be authoritative to demonstrate your understanding of the edges. 7. What are the two mall population emergence models? What organisms may follow those growth models? 8.What factors influence the populations described in 6? How do density-dependent and density-independent factors play a role? Chapter 41 1 . What are the five mall types of Interspecies Interactions discussed In the chapter? Describe each. . When Interactions result In a invalidating outcome for one species (e. G. Parasitism, predation, herbivore), the species that is affected will typically have a response to prevent that negative outcome. Describe examples of how species respond to these effects. 3.How do invasive species affect the natural populations? 4. What is the difference between a feed chain and a food web? 5. What type of ecosystems would likely demonstrate bottom-up control? top-down control? Why? 6. Is ecological disturbance a bad thing? Why or why not? Give an example to support your answer. 7. How did MacArthur and Wilson demonstrate the connection between theater and species richness & transformation? Chapter 42 1 . Why do ecologists need t o understand the laws of thermodynamics? How do they apply to an ecosystem? 2.How much strength Is being transferred for each atrophic level? 3. What is primary production? What limits primary production in aquatic ecosystems? Why is primary production so low in the open ocean? 4. Why underside we say that biochemical cycles are natures way of recycling? 5. List the inputs and outputs (to the atmosphere) of each of the following biochemical cycles a. weewee cycle b. Carbon cycle d. Phosphorus cycle Chapter 43 1. What are the three levels of biodiversity? Is one level more important to study than the others?Why or why not? 2. What are the threats to biodiversity? Describe specific examples of each. 3. Why are small populations at risk? Describe specific issues associated with small populations. 4. Should we preserve flat coat in multiple small patches or one commodious patch (SOLOS theory single large or several small)? Using your knowledge of landscape structure and biodiversi ty, how would you establish a protected area and why? 5. How does climate change affect species diversity and distribution? 6. What do we mean by the term sustainability?
