Deer are brought to an area lush with vegetation and no real predators. The deer population was monitored over time, and population data were recorded as shown in the graph. Which set of statements best describes the data collected?
The deer population exceeded the carrying capacity, providing predators with a surplus of food. As the deer population decreased, so did the carrying capacity.
The deer population increased as the carrying capacity stabilized. As the carrying capacity decreased, the deer population decreased.
As the deer population reached a maximum, so did the carrying capacity. As the deer population decreased, so did the carrying capacity until the environment stabilized and the deer population could increase again.
The deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there was less food available, reducing the carrying capacity.
The deer population increased rapidly, quickly exceeding the carrying capacity. As the deer population increased, there was less food available, reducing the carrying capacity. For this growth curve to continue increasing, which of these must occur?
The organisms must adapt to a new habitat.
The organisms must migrate to a new environment.
The resources in the environment must be unlimited.
The environment must provide a habitat for a large variety of organisms.

A harmless scarlet king snake and a venomous eastern coral snake have similar band patterns, as shown below. For the scarlet king snake, the adaptation of having a banding pattern like the eastern coral snake’s is known as mimicry. The outcome of this adaptation in the scarlet king snake is to —
make it easier for the scarlet king snake to attract prey
make it easier for the scarlet king snake to interbreed with the other snake
allow the scarlet king snake to blend in with its environment
protect the scarlet king snake from predators

Which statement is best supported by the information in the graph?
N2O levels will begin to decrease, stopping ozone layer depletion.
CO2 levels will continue to rise, increasing average global temperatures.
CH4 levels will increase further, decreasing average global temperatures.
All greenhouse gases will have a rapid decline, returning to levels prior to the 1500s.
Which environmental concern is most associated with burning fossil fuels?
global climate change
pollution of ocean waters
ozone layer destruction
decrease in levels of atmospheric carbon dioxide
Excess carbon gases released into the atmosphere cause additional radiation to be retained and Earth's average temperature to increase. This phenomenon is known as-
solar radiation.
the ozone shield.
the greenhouse effect.
industrial air pollution.
What is the role of the greenhouse gases in the atmosphere?
They trap some of the Sun’s heat energy within the atmosphere, helping to maintain Earth’s average temperature.
They prevent most of the Sun’s rays from reaching Earth, thereby preventing Earth from heating up.
They divert the Sun’s heat from the equator to the poles, causing the ice caps to melt, leading to global warming.
They destroy the ozone layer, allowing harmful ultraviolet rays of the Sun to reach the surface of Earth.
Pesticides, such as DDT, often have harmful effects on aquatic ecosystems. One harmful effect would be that these pesticides
cause fish to become sterile and unable to lay eggs.
cause algae and plants to overgrow and pollute the water when they die.
accumulate in animals and build up in toxic concentrations as they pass through the food chain.
eliminate most of the algae and plants in the food chain, causing animals to starve, at higher levels of the food chain.
Instead of clear-cutting land and moving on, a local lumber business decides to start farming trees: cutting some of the trees and planting the fields they have just cut with saplings. Compared to the old method of clear-cutting, the impact this new strategy will have on the environment is best described as what?
Positive, since the lumber company will immediately make more money.
Negative, since it is destroying much of the environment.
Positive, since it is a sustainable plan to use a renewable resource.
Negative, since it is a sustainable plan to use a renewable resource.
