Quarter 2 Bio Practice Final

Front

What is the role of carbon dioxide in aquatic ecosystems?

Back

Carbon dioxide is essential for photosynthesis in aquatic plants, which use it to produce oxygen and glucose.

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation of the energy flow in an ecosystem, showing the energy available at each trophic level.

Front

What happens to energy as it moves up the food chain?

Back

Energy decreases as it moves up the food chain due to energy loss at each trophic level, primarily through metabolic processes.

Front

What is photosynthesis?

Back

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

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

How do plants help reduce carbon dioxide levels in an ecosystem?

Back

Plants absorb carbon dioxide during photosynthesis, which helps lower its concentration in the environment.

Front

What is the significance of the large-mouth bass in an ecosystem?

Back

The large-mouth bass is a key predator in freshwater ecosystems, helping to maintain the balance of fish populations.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in cellular respiration to produce energy, carbon dioxide, and water.

Front

What factors can affect the levels of oxygen and carbon dioxide in a closed aquatic system?

Back

Factors include the number of plants and animals, light availability, and water temperature.

Front

What is the importance of aquatic plants in a lake ecosystem?

Back

Aquatic plants provide oxygen, food, and habitat for various organisms, and they help stabilize the ecosystem.
