Remediation EOC Review (Human Impact)

Front

What is bioaccumulation?

Back

Bioaccumulation is the process by which substances, such as pesticides or heavy metals, accumulate in an organism's body over time, often leading to toxic effects.

Front

How do introduced species impact native ecosystems?

Back

Introduced species can compete with native species for resources, potentially leading to declines in native populations and altering ecosystem dynamics.

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms, playing a crucial role in regulating Earth's climate.

Front

What happens to deer populations when their habitat is reduced?

Back

When habitat is reduced, deer populations may decrease due to less available food and increased competition for resources.

Front

What is ecosystem stability?

Back

Ecosystem stability refers to the ability of an ecosystem to maintain its structure and function over time, even when faced with disturbances.

Front

What role do natural disasters play in ecosystem stability?

Back

Natural disasters can disrupt ecosystems, but stable ecosystems often recover over time if left undisturbed.

Front

What is the significance of the nitrogen cycle?

Back

The nitrogen cycle is essential for converting nitrogen in the atmosphere into forms usable by living organisms, supporting life on Earth.

Front

How does human activity affect the phosphorus cycle?

Back

Human activities, such as agriculture and wastewater discharge, can disrupt the phosphorus cycle, leading to nutrient pollution and algal blooms.

Front

What is the impact of fossil fuel combustion on the environment?

Back

Combustion of fossil fuels releases carbon dioxide and other greenhouse gases, contributing to climate change and altering the carbon cycle.

Front

What is competition in ecosystems?

Back

Competition occurs when organisms vie for the same resources, such as food, water, or space, which can affect population dynamics.
