A mountain lion population recently experienced a drop in population size. Which of the following would best describe the limiting factor that is involved? A change occurred in the genetic variability. The deer population experienced a rapid decline due to a parasite.

Which best describes how an organism's niche is determined? An organism's habitat and inherited traits determine its niche. An organism's habitat and ability to reproduce determine its niche.

A trout population grew from 4 in 1992 to 16 in 1993 and then to 64 in 1994. If it continued to grow exponentially, approximately how many trout were there in 1995? 100 128 256

Scientists use specific levels of organization to analyze the biosphere. The Everglades consist of a large area of subtropical wetlands in Florida. Various species of plants and animals can be found in the Everglades, including panthers, cypress trees, herons, and alligators.The group of ecosystems on Earth that feature climate, vegetation, and wildlife similar to the Everglades is a biosphere. a community. a population. a biome

Interactions between organisms and their environment impact the organism's overall population. The jaguar Panthera onca is the largest cat in North America. It is found in areas across the Southwest, including Arizona, New Mexico, and Texas. It is a carnivore that has powerful jaws and sharp teeth and preys on fish, turtles, and many smaller mammals. Which shows the relationship between the jaguar and turtles? adaptation principle competitive exclusion principle niche principle predator-prey relationship

Earth scientists have concluded that the methods of harnessing energy that have been used over the past two centuries, such as the burning of fossil fuels, are causing climates around the world to change more quickly and suddenly than ever before in human history. Evidence includes increased air temperatures, rising sea levels, and the shrinking of glaciers in Greenland, Alaska, and other regions of Earth. The most complex level of organizational hierarchy that climate change could potentially affect is Earth's biosphere.

Review the picture below.Which would be the most accurate title for this picture? primary succession after a controlled fire primary succession after a volcanic eruption

Ground squirrels are found in many areas of the United States. They live in underground burrows and are often attacked by birds of prey, coyotes, and bobcats. Which of the following is a limiting factor for a ground squirrel population? a population of tree squirrels a population of hawks

The Serengeti plains are part of the African savanna ecosystem and are home to a variety of different species of plants and animals. The Serengeti plains experience a seven-month period of seasonal drought each year, during which the ecosystem receives only four inches of rain and the availability of some resources becomes very scarce.Which type of limiting factors does the seasonal drought in the Serengeti plains affect? density-independent factors

Rainforests around the world are being cleared at an alarming rate to make room for new communities, agriculture, mining, and roads, and to provide lumber for construction and furniture.How might the destruction of rainforests affect the balance of gases in Earth's atmosphere? by increasing carbon dioxide and decreasing oxygen

Which sustainable practice is paired correctly with its impact on the environment? Using bamboo results in an increased use of forest trees.

An ecosystem has experienced a flood. Which type of plants would you expect to see growing first after the flood? shrubs lichen small annual plants

Which human activity is correctly paired with the greenhouse gas that it increases? rice cultivation and water vapor landfilling and carbon dioxide deforestation and methane sewage treatment and nitrous oxide

Ash trees are being removed when they show signs of the ash borer, a parasite that affects only ash trees and kills them off.What best explains why the ash trees are being cut down? The ash borer is a density-independent limiting factor, and humans need to clear cut to control tree density. The ash borer is a density-dependent limiting factor and will start to spread to nearby healthy trees.

Review the chart, which shows the population sizes of three African animals in 1990 and in 2000. Population Estimates of Animals in Africa in 1990 and in 2000 19902000Lions100,00047,000Cheetahs50,0007,500Zebras15,0002,500Which explanation is best supported by the numbers in the chart? Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetahs. The dwindling zebra population has led to the decline of the predator lion and cheetah populations.

cGrass starts with 30,000 kcal of energy. A cheetah would acquire ()(300)kcal of energy after it ate a zebra that had consumed the grass.

The map shows the distribution of wild boars in the United States (shaded area).Which of these facts about wild boars is best supported by the evidence provided? Wild boars were brought to the United States by humans. Wild boars have quickly spread through the United States. Wild boars have established successfully mostly in areas with warm climates. Wild boars have a high reproductive rate and no natural predators

Which statement best compares consumers and decomposers? Both get their energy by feeding on other organisms.

What would most likely happen if there were no condensation stage in the water cycle? Water could not convert from a gas to a liquid.

Which statement describes the relationship between plants, animals, and the carbon cycle? Plants use carbon and release oxygen, and animals release carbon and use oxygen.

White perch is a fish that is native to Atlantic coastal regions and is invasive to the Great Lakes. It feeds on native species and is thought to be the cause of the decline of the Great Lakes walleye fish populations. What was most likely its mode of introduction? produce brought from the eastern states
