Human Impact Practice Flashcard

Front

What is habitat destruction?

Back

Habitat destruction refers to the process in which natural habitats are rendered unable to support the species present, leading to a loss of biodiversity.

Front

How do ecosystems demonstrate interconnectedness?

Back

Ecosystems are interconnected, meaning that changes in one ecosystem can affect others, as seen when pollutants from one area impact water quality in distant lakes and streams.

Front

What is the primary concern when a mining company wants to lease land in a national park?

Back

The primary concern is the threat to local biodiversity, as mining activities can disrupt habitats and endanger species.

Front

What is eutrophication?

Back

Eutrophication is the process where water bodies become overly enriched with nutrients (like nitrogen), leading to excessive growth of algae.

Front

How does eutrophication affect oxygen levels in water?

Back

As algae decompose, they consume oxygen, which reduces the amount available for other aquatic organisms, potentially leading to dead zones.

Front

What immediate effect does logging have on the carbon cycle?

Back

The immediate effect of logging is an increase in atmospheric carbon dioxide levels due to the reduction of trees that absorb CO2.

Front

What is the role of nitrogen in fertilizers?

Back

Nitrogen in fertilizers promotes plant growth, but runoff can lead to nutrient pollution in water bodies.

Front

What is the impact of pollution on ecosystems?

Back

Pollution can disrupt the balance of ecosystems, harm wildlife, and degrade natural resources.

Front

What is overexploitation?

Back

Overexploitation refers to the unsustainable use of natural resources, leading to depletion and potential extinction of species.

Front

How can human actions alter ecosystem equilibrium?

Back

Human actions, such as pollution and habitat destruction, can disrupt the natural balance of ecosystems, leading to negative consequences for biodiversity.
