BIO FINAL REVIEW

QuestionAnswer
In a forest ecosystem, a variety of predators compete with one another for the same prey. The predators include wolves, coyotes, foxes, and hawks. Their prey include deer, rabbits, mice, and the chickens that live outdoors on nearby farms and backyards. The hawk population increases to a new carrying capacity that is determined by one or more limiting factors, such as the availability of food.
Brianna is mapping trees in a section of land. She observes that some of the trees are clumped together, some are uniformly separated, and some appear to be spaced randomly. What is she describing? the population distribution
: A scientist concludes that a population of bison has reached the carrying capacity of the prairie where it lives. The birthrate and death rate of the bison population are equal to each other. What can be concluded about the rates of immigration and emig The rates of immigration and emigration are equal to each other
(table shown in question) You collect data on birth and mortality in three populations of squirrels. The following table shows the birth rates (b) and death rates (m) for all three populations. Which population has the fastest growth rate (r)? C
A rabbit population is affected by parasitism and disease, both of which are density-dependent limiting factors. Which statement describes the effects of parasitism and disease on the rabbits? As the density of the rabbit population increases, parasites and disease weaken or kill a greater percentage of rabbits.
Which data are MOST useful for analyzing the climate of the region? average temperatures for July, measured over 30 years
Scientists have observed the exponential growth of lionfish in the Caribbean Sea. Which of these predictions about the future of the lionfish population is the most likely to occur? A limiting factor will cause the growth of the lionfish population to slow down, forming a pattern of logistic growth
A heron is affected by many factors in its environment. What distinguishes the biotic factors from the abiotic factors? living or nonliving
A hurricane blows across a Caribbean island. The storm flattens trees, and it drowns or washes away a large number of plants and animals. As a result of the storm, the carrying capacity of the island is temporarily reduced for many of the island species. The storm is a density-independent limiting factor, because population size and density do not alter the storm’s effect.
Greenhouse gases include carbon dioxide and methane. How do greenhouse gases act to increase air temperatures near Earth’s surface? They trap heat that is radiated from the surface
Lake Tefillin is a large freshwater lake that is popular for recreation. One year, the managers of the lake introduce a population of rainbow trout to the lake. The graph shows the growth of the population over several years. Label each statement with the The population reaches carrying capacity. III The growth rate slows down, due to the effect of limiting factors. II Exponential growth is occurring. I The changes to population size are relatively small, temporary, and difficult to predict. III Many l
Consider the following claim: “Abiotic factors help determine the populations of an ecosystem.” Evaluate this claim using your knowledge of different biomes (rainforest, desert, savanna, taiga, etc). This claim is supported by the interactions between abiotic and biotic factors of the rainforest. In the rainforest, the abiotic factor of water is common in the form of rain. The rain helps the plants to grow, and in turn provides resources like food and
Which of these subjects is MOST LIKELY to be studied in ecology? The interaction between populations of wolves and deer.
The graph shows the changing populations of wolves and moose in Isle Royale National Park. Wolves are predators, and moose are their prey. Which of the following pairs of populations is most likely to increase and decrease in a similar pattern to the wolv Moose and balsam fir, which are the favorite food plants of moose
