Flashcardizz- Test: Threats to Bio-HIPPCO

Front

What is biomagnification?

Back

Biomagnification is the process by which the concentration of toxins increases in organisms at each successive level of the food chain.

Front

Why are top predators more affected by biomagnification?

Back

Top predators are at the top of the food chain and consume organisms that have accumulated toxins, leading to higher concentrations of these toxins in their bodies.

Front

What has been the trend of carbon dioxide levels in the atmosphere over the last 200 years?

Back

The level of carbon dioxide in the atmosphere has increased steadily over time.

Front

What is the primary source of air pollution?

Back

The primary source of air pollution is human activities, such as industrial processes, vehicle emissions, and deforestation.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of species on Earth, including the diversity within species, between species, and of ecosystems.

Front

What factors can affect the rate of evaporation?

Back

Factors that can affect the rate of evaporation include temperature, humidity, wind speed, and surface area.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, including carbon dioxide, methane, and nitrous oxide.

Front

How does deforestation contribute to climate change?

Back

Deforestation contributes to climate change by reducing the number of trees that can absorb carbon dioxide, leading to higher levels of this greenhouse gas in the atmosphere.

Front

What is the significance of keystone species?

Back

Keystone species are species that have a disproportionately large impact on their environment relative to their abundance, playing a critical role in maintaining the structure of an ecosystem.
