Exam Review (mix of all units-mostly Units 5-8)

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius. In aquatic ecosystems, water has a high specific heat capacity, meaning it absorbs heat slowly and releases it slowly.

Front

What is an anthropogenic cause of air pollution?

Back

An anthropogenic cause of air pollution is any pollution that originates from human activity. An example is industrial processes, which release pollutants into the air.

Front

What is a major source of methane production in agriculture?

Back

A major source of methane production in agriculture is fermentation in ruminant animals (livestock), such as cows and sheep, during digestion.

Front

How does biodiversity change during ecological succession?

Back

Biodiversity increases as the ecosystem matures and stabilizes, leading to a more complex and diverse community of organisms.

Front

What is a sustainable solution to food waste?

Back

A sustainable solution to food waste is to create a household compost bin, allowing decomposed food wastes to be used as fertilizers in gardens.

Front

What is the role of water in regulating temperature in aquatic ecosystems?

Back

Water regulates temperature in aquatic ecosystems by absorbing heat slowly and releasing it slowly, which helps maintain stable temperatures.

Front

What are some examples of anthropogenic sources of air pollution?

Back

Examples of anthropogenic sources of air pollution include vehicle emissions, industrial discharges, and agricultural practices.

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, leading to a more stable and mature community.

Front

What is the impact of biodiversity on ecosystem stability?

Back

Higher biodiversity generally leads to greater ecosystem stability, as diverse ecosystems are better able to withstand environmental changes and disturbances.

Front

What are the benefits of composting food waste?

Back

Composting food waste reduces landfill use, decreases greenhouse gas emissions, and produces nutrient-rich soil for gardening.
