ESRMlOO Questions Autumn 2006 Chapter 3 l The principle of describes how each environment has lower and upper thresholds beyond which a particular species cannot survive or reproduce A species abundance B natural selection C tolerance limits D selective pressure 2 is a term used to describe an individual organism that is able to adapt to a changing environment using a limited range of physiological adaptation which is not passed onto their offspring A Evolution B Acclimation C Mutation D Speciation 3 Cheetahs are the fastestrunning mammals in the world This evolutionary adaptation has not been achieved by the other big cats living in the same territory This process of separating species into new types is called A divergent evolution B ecological niche C acclimation D tolerance limits 4 The is a description of either the role played by a species or the total set of environmental factors that determine species distribution A Biotic potential B Commensal function C Ecological niche D Synergistic function 5 The states that no two species will occupy the same niche and compete for exactly the same resources in the same habitat for very long example several species of wood warblers use different strata of the same forest A Principle of Limiting Factors B Law of Competitive Exclusion C Theory of Divergent Evolution D Law of Competitive Advantage 6 The giant panda is an example of an that has adapted to feed exclusively on bamboo and many starve when huge acreages of bamboo ower and die A opportunist B commensalist C generalist D specialist 7 Weeds such as dandelions which reproduce quickly and easily spread their seeds long distances can be described as A epiphytes B opportunists C consumers D parasites 00 Which of the following is not a predator A Herbivores B Camivores C Omnivores D Detritovores 9 Competition among members of the same species is called competition A mutualistic B intraspecific C antagonistic D interspecific 10 Young grizzly bears are forced to leave their parents territory as soon as they are independent This is an example of how organisms cope with competition A Mutualistic B Intraspecific C Antagonistic D Interspecific 11 Which of the following is NOT an example of a keystone species A wolfs B tropical figs C mycorrhizal associations D poison arrow frogs 12 Some species demonstrate a cyclic overshoot followed by dieback as the carrying capacity of the enVironment is passed when the population size increases Which of the following is a GOOD example of this pattern of boom and bust population cycle A algae growing in a lake B migratory locust in the desert C tropical trees D symbiotic partnerships 13 is a symbiotic relationship in which one species benefits and the other is harmed A Parasitism B Commensalism C Endemism D Antagonism E Mutualism 14 mimicry involves two dangerous or unpalatable species that have evolved to look alike so predators avoid both species A Mullerian B Batesian C Darwinian D Straussian 15 Which of the following would describe the exponential growth of a population A 1 2 3 4 5 6 B 32 16 8 4 2 1 C 1 3 5 7 91113 D 1 2 4 8 16 32 16 The graph of a positive exponential growth curve resembles A the letter S B the letter C C the letter J D the letter U 17 When a population overshoots or surpasses the carrying capacity of its environment which of the following is NOT likely to happen A Death rates will begin to surpass birth rates B The population growth curve will become negative C A population crash may occur D Birth rates will begin to surpass death rates 18 In growth species are more in equilibrium with the availability of environmental resources so that population sizes are more stable A exponential B logistic C irruptive D cyclic 19 Some growthlimiting factors such as disease and stress increase mortality rates as populations increase These factors are called A intrinsic B extrinsic C densitydependent D densityindependent 20 Some organisms such as dandelions persist in a given environment by depending on a high rate of reproduction and growth These organisms tend to have exponential growth rates and are described as A Hadapted B Kadapted C gadapted D radapted 21 A community s is the rate of biomass accumulation or the conversion of solar energy into chemical energy stored in living or onceliving organisms A recycling potential B primary productivity C biotic transformation rate D successional rate 22 is the number of different species in an area It is a useful measure of the variety of ecological niches or genetic variation in a community A Complexity B Density C Abundance D Diversity 23 refers to the number of species at each trophic level and the number of trophic levels in a community A Resilience B Complexity C Profusion D Abundance 24 refers to patterns of spatial distribution of individuals and populations within a community as well as the relation of a particular community to its surroundings A Community complexity B Successional stage C Ecological structure D Ecological stability 25 The boundaries between adjacent communities are called A ecotones B ecosystem divisions C niche overlap zones D ecological partitions 26 is the process by which organisms occupy a site and gradually change environmental conditions by creating soil shade shelter or increasing humidity A Ecotone development B Resource partitioning C Ecological succession D Competitive exclusion 27 occurs when an existing community is disrupted by a natural catastrophe or human activity and a new one subsequently develops at the site A Primary succession B Secondary succession C Niche overlap D Habitat fragmentation
