Living Environment Regents DRILL 1

Front

What are biological catalysts?

Back

Biological catalysts, also known as enzymes, are proteins that speed up chemical reactions in living organisms without being consumed in the process.

Front

What is the role of green plants and algae in an ecosystem?

Back

Green plants and algae are producers that convert sunlight into energy through photosynthesis, forming the base of the food chain.

Front

What is the function of lymphatic capillaries?

Back

Lymphatic capillaries collect excess interstitial fluid and transport it back to the bloodstream, playing a crucial role in fluid balance and immune response.

Front

What are producers in an ecosystem?

Back

Producers are organisms that create their own food through photosynthesis or chemosynthesis, serving as a primary energy source for consumers.

Front

What is the function of stomates in plants?

Back

Stomates are openings on the surface of leaves that regulate gas exchange, allowing carbon dioxide in and oxygen out, essential for photosynthesis.

Front

What is the significance of CO2 for green plants?

Back

CO2 is essential for photosynthesis, the process by which green plants convert light energy into chemical energy, producing glucose and oxygen.

Front

How do the circulatory and lymphatic systems work together?

Back

Both systems transport substances throughout the body; the circulatory system moves blood and nutrients, while the lymphatic system helps in immune response and fluid balance.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil, which supports plant growth and maintains ecosystem health.

Front

What are the main components of the circulatory system?

Back

The circulatory system consists of the heart, blood vessels, and blood, responsible for transporting oxygen, nutrients, and waste products.

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 chlorophyll.
