During secondary succession, mosses lichen and fungi live, die, leaves remain, and help promote growth on the ecosystem. After, grasses and vascular plants are able to grow and replace the pioneer species in the ecosystem. What pre-existing condition allowed for the growth to occur?
the growth of vascular plants
addition of animals
the creation of soil
the pollination of trees

A small lake ecosystem receives regular amounts of acid rain. Over time, the acid in the rain collects in the small lake. Which of the following is a likely effect of this condition?
the acid will increase the growth of basic organisms such as mosses and lichen
all the acid will be collected in the flowering plants and removed from the ecosystem
organisms high on the food chain will grow out of control

Two species of small birds live together in the forest ecosystem but do not directly compete for shelter, food, or other resources. What is the most likely way a decrease in the population of one of the species could cause a change in the population of the other species?
The two species could occupy the same niche, so that a decrease in one population would provide for an increase in the other.
The two species could have a shared predator, so that a decrease in one population would encourage the predator to eat more of the other population
One of the species may need to mate with the other species in order to reproduce, so that a decrease in one population would cause a decrease in another
Neither of the species could be well adapted to its environment, so that a decrease in one population encourages the other population to abandon environment.
Five different species of beetles occupy different niches in a small island ecosystem. A new species of beetle, the better beetle, is introduced to the island by humans.

The better beetle will reproduce slowly and for a new niche
The better beetle will take the place of a the five indigenous beetles
The better beetle will compete with all five beetle species and replace all or most of them
The better beetle will be unable to survive and will go extinct

Biologists have worked to bring the population of the whooping crane up from a recorded low of 16 in the world in the 1940's . From 1940 to 1970, their methods included establishing protected breed, migrating, and wintering grounds. from 1970 onward, programs were also introduced to breed chicks in captivity , then use ultra light aircraft to loo like adult cranes to guide the captive bred cranes along natural migratory routes. look at the table. Which of the following statements best supports the information in the passage and the table above?
Only preservation practices, use d alone, were effective in supporting whooping crane population.
Preservation practices alone were ineffective in supporting the whooping crane population.
Conservation practices provided no benefit compared to preservation practices alone.
Conservation and preservation together led to a greater population increase than preservation alone.
A class will conduct an experiment using local soil to grow bean plants. Certain beans plants will be given an additional phosphorus-based fertilizer.

Most children use anywhere from 8,000 to 10,000 disposable diapers during their infancy and early childhood. This consumption leads to the disposal of an average of 18 BILLION diapers each year.

The Haynesville Shale formation is a geological feature located beneath northwest and north central Louisiana. Initial estimates suggest the formation might well be the largest on shore reserve of natural gas in t he United States.

speed up environmental impact studies and rush, then grant land leases for natural gas companies to drill for the gas all at once
commission sustainable development studies, then grant leases for natural gas companies in select areas
develop alternative energy sources instead, since natural gas is a fossil fuel that releases carbon dioxide upon combustion
wait until the cost of natural gas rises, then drill for the gas to maximize the potential for profits
In the late 1970's , and through the 1980's, scientists discovered and proved that chlorofluorocarbons (CFC's) were destroying the ozone layer of Earth's Atmosphere.

the disposable item could be burned to release energy so it gains the advantage of producing less environmental pollution
the disposable item could be placed in boiling water so it gains the advantage of being easily cleaned
China is now considered by some to be "the world's factory" because so much manufacturing is done there. In the weeks prior to the 2008 Summer Olympics in Beijing, industrial production in and around the city was suspended due to concerns about air quality. What does this most likely suggests about the quality of life along much of China's eastern seaboard, where industrial activity is concentrated?
The standard of living is low because there are too few jobs to keep the populace employed.
Rates of illness are high because of the by-products of industrial activity.
The standard of living must be high because the economy can afford to shut down for weeks at a time.
Rates of illness are low because of the by-products of industrial activity.
Which sequence correctly traces the flow of industrial pollutants from point sources to organism?

In certain places, it is illegal to catch and keep female members of certain species of fish. Fishermen are expected to observe the practice of "catch and release." Why is public support among fishermen likely to be high for this practice?
The rule is intended to protect females so they can reproduce to keep fish populations healthy.
The rule is intended to be a source of money so agencies have funds to spend on public interests.
The public has a natural bias for protecting certain genders of animal populations.
Most fishermen do not keep fish anyway, so the impact of this rule is negligible.
