Exponential growth is rare because resources are usually limiting. True False Question 16 1 pts Like nutrients and water, energy also cycles through an ecosystem True False Question 17 1 pts Island biogeography predicts that a single large area would have higher biodiversity than several small areas. However, in practice, several small areas could have an advantage for minimizing edge effects. True False
Question 18 1 pts Lions, leopards and other large terrestrial predators generally maintain well-defined territories What kind of dispersion pattern would you expect this to produce? O clumped O clustered O uniform O logistic O random
Question 19 1 pts Three quarters of new infectious diseases originate in animals. Thus, outbreaks are becoming more common. True False Question 20 1 pts is the amount of energy available to consumers in an ecosystem. O Net primary production Respiration O Actual primary production O Trophic primary production O Gross primary production Question 21 1 pts Why is a random dispersal pattern quite rare in nature? O Because resources in nature are rarely randomly spaced. O Because only aquatic resources are commonly randomly dispersed. O Because most animals have social behavior such as forming flocks or herds O Because most organisms have overlapping territories created via symbiosis. O Because most organisms have defined territories created via competition Question 22 1 pts From this list, which one is a indicator species O gray wolves O any species of whale O american robins O polar bears O cotoyes Question 23 1 pts The Earth's surface releases that is absorbed by the atmosphere, stabilizing or raising the atmospheric temperature, a process known as "greenhouse effect". O infrared (heat) radiation O beta radiation ultraviolet radiation O near-ultraviolet radiation X-rays Question 24 1 pts r-selected species tend to have type III survivorship curves. O True O False Question 25 1 pts Atmospheric CO2 has increased since about the year 1850; most of this atmospheric increase is due to increased respiration by terrestrial organisms. decreased rates of photosynthesis. burning of fossil fuels. evapotranspiration increased respiration by marine organisms. Question 26 1 pts You are in a biome that lacks larger mammals (e.g., rhinos and elephants), it is mostly warm and humid, and it lacks a clear seasonality. What biome is this? O High desert Tropical rainforest O Tropical grassland Temperate rain forest Taiga Question 27 1 pts How does DDT in the environment affect many birds? stunted growth of chicks advancing neurological degeneration does not accumulate in the blood and other water-based body fluids. O chronic liver failure in adults egg shells are thinned and this causes a decrease in the reproductive rate Question 28 1 pts Several butterfly species that are edible to birds have very similar color patterns to the inedible monarch butterfly. This is best described as an example of what? O crypsis O intimidation Batesian mimicry Müllerian mimicry O aposematic coloration Question 29 1 pts A community's actual evapotranspiration is a reflection of animal biomass and animal water content the number of plants and how much moisture they avoid the depth of the water table. wind speed and the frequency of wind gusts. solar radiation, temperature, and water availability for plants.
