Question 2 Exponential growth is found in .. (only most inclusive answer gets the point!) O Humans O Your bank account when interest is added once per 6 months O Humans and Bacteria O Birds that nest once per year O Bacteria Question 3 Paul Colinvaux wrote his book in 1977 when global warming was not a accepted concept yet. He states that the atmosphere was at 0.03 percent by volume (=300 ppm). Today we are at roughly 420 ppm, yet he predicts that we might reach 600 ppm. Why did he think 40 years ago that such an increase "might" be problematic? O because a large rise in CO2 will suffocate all life on earth because in 1977 it was not known that greenhouse gases (like CO2) have a noticeable impact on the global climate O because plant growth would get out of hand. because a rise in CO2 will lead to spontaneous combustion because back in the 70s human-caused climate change was not yet an accepted concept, but scientist started to worry about the consequences of the a continuing increase of CO2. Question 4 1 p Some microbiologists call a virus a predator and others may call it a parasite. In an ecological sense, why are both terms actually incorrect. O Viruses are consuming only parts of their host and therefore are neither parasites nor predators . Predation and parasitism are resource-consumer relationship and strictly speaking viruses are not using resources. Viruses have no effect on the reproductive rate of their host. Viruses can have positive effects on plant or animals by attacking detrimental bacteria. Question 5 According to the meta population model, which of the four patches should have the largest population? O A large patch close to other large patches O A small patch close to a large patch O A patch that is large and isolated O A large patch close to other small patches O A patch that is small and far from others Question 6 Which of the following statements about parasites is not correct a parasite may be specific to a single host species O a parasite may increase the likelihood that its host will die from other causes O a parasite may reduce the fecundity of its host O a parasite will always kill its host Question 7 Many factors can affect population growth and among them are density dependent factors . Which of the following is NOT a density dependent factor? O space O food sources O parasitism and disease extreme weather events predation
