Small fish eating bacteria and phytoplankton, which both contain relatively high levels of mercury, is an example of:
When small fish eat bacteria and phytoplankton which contain relatively high levels of mercury, they accumulate the mercury into their tissues. This describes the process of bioaccumulation.

Why is acid rain so harmful to marine species?
"Acid shock" typically occurs during the spring time, when snow (which has retained and accumulated pollutants) begins to melt and runoff into lakes and rivers. Another detrimental effect of acid shock occurs during the spawning/developing stages of aquatic animals. For example, some salamanders and frogs prefer to lay eggs in "vernal pools", or temporary puddles of water only present in the spring. Acid shock can cause these pools to become too acidic; the eggs cannot properly develop, and they die off.

Which definition best describes the process of eutrophication?
The algal blooms that result from agricultural runoff do not consume oxygen when they are living. The resulting die-off from overcrowding and lack of sunlight availability and decomposition process is what consumes oxygen in the ecosystem, causing fish to suffocate.
It is also important to recognize that hypoxia is the result of insufficient oxygen in the ecosystem, while hyperoxia is when there is too much oxygen. (Consider the meanings of the prefixes "hypo-" and "hyper-".)

Which of the following most accurately describes the dominant theme of Rachel Carson's book Silent Spring?
Rachel Carson's Silent Spring focused primarily on the widespread application of pesticides, the lack of government regulation of said pesticides (especially DDT), and their negative impacts on bird populations (i.e. songbirds that were at risk and would result in a spring lacking their songs). The book challenged industry claims that downplayed toxicity of their products and triggered a grassroots environmental movement that helped create the U.S. Environmental Protection Agency.

In the United States, garbage—municipal solid waste—most commonly exists in which of the following forms?
As of 2013, paper products made up 27 percent of the United States' municipal solid waste.

Reducing the occurrence or frequency of a disaster or issues is best defined as?
Mitigation is defined as actions taken to prevent or reduce the occurrence of natural disasters and damage to an environment. Restoration is the renewal of an environment or ecosystem after it has been almost or completely destroyed. Preservation is a collection of efforts aimed at sustaining a vulnerable or unstable ecosystem. Remediation is often the clean up or removal of contaminants from an environment.

It's known that pollution can have negative impacts on human health, economics, and ecological communities. Which of the following is not an effect of pollution?
The correct response is biodiversity conservation . Pollution alters ecological communities by adding harmful chemicals, substances, and abiotic factors into the environment. This has a negative effect on biodiversity - not a positive effect. Thus, we would not except for species to be conserved in a region with pollution. We know that pollution can lead to acid rain, contaminated water, and ozone depletion so those answer choices are incorrect.

What is a potential result of fertilizer runoff into streams and rivers?
Fertilizer runoff can cause eutrophication, where nutrient-enriched freshwater mixes with saltwater and causes huge algal bloom, such as red tide. These can be toxic to both ocean organisms and to humans.
