If you atomic number 18 a biologist interested in working in the tropical rainforests, briefly describe a research study you could complete at each(prenominal) level in the biological hierarchy, starting from the organisms level to the biosphere. 2. What atomic number 18 the two biotic variables that dictate type of terrestrial bimbo? Do aquatic and marine systems rely on the same two variables? wherefore or why not? 3. Which of the terrestrial boomers Is the most vulnerable to anthropogenic (human) cast and why?What Is being stirred? 4. Create a table that lists the bimbo, biotic variables that be elevate, and examples of organisms that would reside there. 5. Why arena species all over the orbiter? What influences dispersal? 6. What is the value of describing populations using density, dispersion, and demographic information? Be ad hoc and be sure to demonstrate your understanding of the bournes. 7. What are the two center population growth models? What organisms may foll ow those growth models? 8.What factors influence the populations set forth 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? calculate each. . When Interactions result In a ostracize 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 residue between a food chain and a food wind vane? 5. What type of ecosystems would likely demonstrate bottom-up wangle? 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 area and species richness & diversity? Chapter 42 1 . Why do ecologists need to un derstand the laws of thermodynamics? How do they apply to an ecosystem? 2.How very much energy Is being transferred for each atrophic level? 3. What is primary business? What limits primary occupation in aquatic ecosystems? Why is primary production so low in the open ocean? 4. Why john 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. Water cycle b. Carbon cycle d. daystar cycle Chapter 43 1. What are the three levels of biodiversity? Is one level much 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 take a chance? Describe specific issues associated with small populations. 4. Should we preserve land in double small patches or one large patch (SOLOS theory wiz large or several small)? Using your knowledge of landscape anatomical structure and biodiversity, how would you establish a protected area and why? 5. How does climate depart affect species diversity and distribution? 6. What do we mean by the term sustainability?
