Chapter 52, Problem 7TYU
Summary Introduction
Introduction: In ecology the stratification refers to the process in which the vertical layering of habitat occurs. It is arranged according to the layers of the vegetation. Each of the layers is inhabited by different plant and animal species according to their requirements and preferences.

A biome is characterized by seasonal rainfall (about 20 to 100 mm) and temperature (about -10 to 35OC). Globally, the biome is found around 30ON latitude, has many tree species that lose their leaves in the winter, some shrubs and grasses, insects, many medium to small-sized mammals, birds, lizards, and some snakes. This best describes a:
Group of answer choices

- This biome is a tropical grassland interspersed with widely spaced trees. (a) temperate rain forest (b) tropical rain forest (c) savanna (d) temperate grassland (e) chaparralarrow_forwardBiologists have observed much more similarity in species composition among boreal forests and among areas of tundra in Eurasia and North American than among areas of tropical rain forests or among Mediterranean woodlands around the globe. Can you offer an explanation of this contrast based on the global distribution of these biomes?arrow_forwardTwo islands exist in the eastern Pacific. The animal and plant life on both islands were wiped out by a freak storm at the same time. Island "A" is 100 miles off the coast of Peru; whereas island "B" is only 10 miles off Peru's coast. Island "A" is much smaller than island "B" (20 square miles as opposed to 75 square miles). Which island has a higher species richness equilibrium ? Explain why using the Theory of Island Biogeography.arrow_forward
- What are the flaws ? A biome is a large-scale community of organisms, primarily defined on land by the dominant plant types that exist in geographic regions of the planet with similar climatic conditions. A tropical rainforest is warm, has year round growth, and a high amount of precipitation. Deserts are very hot during the day, cold at night, and have very little precipitation. Temperate grasslands and forests have seasonal changes in temperature and receive a moderate amount of rain. Tundras are very cold, have extremely short growing seasons, and receive a high amount of precipitation. The light, temperature, flow regime, and dissolved solids define aquatic biomes. Estuaries are an important biome that connects ground water and surface water. As you move north of the equator, temperatures decrease and winters get longer. Rainforests are typically found close to the equator in areas of high precipitation. Deserts are typically found 15-30o north or south of the equator in areas of…arrow_forwardWhich of the following statements about biomes is false? a. Chaparral is dominated by shrubs. b.

What pioneer species would have been observed in this ecosystem? F. grasses and wildflowers G. lichens and mosses H. shrubs and saplings J. vultures and coyotesarrow_forward
- Following the Industrial Revolution, populations of dark peppered moths increased, while light peppered moths decreased in London. Higher emissions of industrial pollutants caused tree bark to become coated with soot over time, making the darker-colored moths less visible to avian predators. Ecologists studied the moths present on the bark of trees and noted their body colors over a period of 150 years, and the results are shown in the graph below. Based on the information shown in the graph, which statement best explains the changes in moth populations following industrialization?" 100 80 60 Preindustrial 40 20 1800 1850 1900 1950 Postindustrial Year Within the overall moth population in London, dark-colored moth numbers decreased while light-colored moth numbers increased.

(a) chaparral (b) boreal forest (c) tundra (d) northern deciduous forest (e) savannaarrow_forwardSome people think that our most environmental goals should be to sharply reduce the rate of population growth in the less-developed countries, where at least 92% of the world’s population is expected to take place between now and 2050. Others argue that the most serious environmental problems stem from high levels of resource consumption per person in more-developed countries, which have moreecological footprints per person. What is your view on this issue? Explain.arrow_forward
