Question
62. The carrying capacity of an area is determined by A. food, temperature, and diseases C. B. diseases, predators, and space D. all of these answers are true light, diseases, and the season of the year E. none of the above are true 63. In the graph depicted above, curve A is the A. logistic growth curve; maximum sustainable yield C. logistic growth curve; carrying capacity E. camying capacity; logistic growth curve and curve B is the B. logistic growth curve: exponential growth curve D. exponential growth curve; logistic growth curve 64. How does exponential growth differ from logistic growth? A. Long-term exponential growth is more commonly observed than long-term logistic growth in nature B. Exponential growth models include consideration of a population's carrying capacity C. Logistic growth models take the population's age-structure into account D. The logistic model of growth incorporates environmental limitations on population size E. Logistic growth generally comes with infinite expansion. 65. Whch factor is MOST LIKELY to have a density-independent influence on population growth? B. availability of essential nutrients E.extreme weather conditions C infectious diseases A. abundance of prey D. availability of shelterExplanation / Answer
Please find the answers below:
Answer 62: Choice D (The carrying capacity of an environment/area depends upon multiple biotic and abiotic factors which together determine the population diversity and growth in that area)
Answer 63: Choice D (An exponential growth curve extends from the initial value and reaches a peak value very soon. On the other hand, the logistic growth curve follows a sigmoidal growth pattern in S-shape)
Answer 64: Choice D (The logistic growth model is dependent upon the number and nature of resources present in the environment and hence the mutual competetion between species for these resources. This is why the population under logistic growth undergoes a stationary phase after a period of exponential growth due to limited number of resources)
Answer 65: Choice D (Generally, the availability of shelter does not pose a problem to the natives of an area in order to survive over there since random migrations, shifting and re-localization naturally takes place to these organisms in order to sustain better against the environment)
