Ch 6 Ecosystems and Climate

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect. Examples include carbon dioxide and methane.

Front

What is eutrophication?

Back

Eutrophication is the process by which a body of water becomes overly enriched with nutrients, often due to runoff from fertilizers, leading to excessive growth of algae and depletion of oxygen.

Front

What are the three main types of aquatic life zones?

Back

The three main types of aquatic life zones are freshwater, saltwater, and brackish bodies of water.

Front

Why do tropical regions receive more precipitation?

Back

Tropical regions receive more precipitation due to intense solar radiation, which increases evaporation and moisture in the atmosphere.

Front

What is the impact of overgrazing on grassland ecosystems?

Back

Overgrazing can lead to soil degradation, loss of plant species, and reduced biodiversity in grassland ecosystems.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is the role of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that helps regulate Earth's temperature by trapping heat in the atmosphere.

Front

What is ocean acidification?

Back

Ocean acidification is the process by which the ocean becomes more acidic due to increased carbon dioxide absorption, affecting marine life and ecosystems.

Front

What are the effects of deforestation on ecosystems?

Back

Deforestation leads to habitat loss, decreased biodiversity, and increased carbon emissions, contributing to climate change.

Front

What is the significance of biodiversity in ecosystems?

Back

Biodiversity is crucial for ecosystem resilience, providing stability, productivity, and the ability to adapt to changes.
