Biology Exam: Energy & Matter

Front

What are nutrients?

Back

Nutrients are chemical substances that living organisms need to survive. They are essential for growth, metabolism, and overall health.

Front

What is the role of carbon in photosynthesis and cellular respiration?

Back

Carbon is a key element that is cycled between the Earth's atmosphere and living organisms through photosynthesis and cellular respiration.

Front

What cycle do fossil fuels belong to?

Back

Fossil fuels are part of the carbon cycle, which involves the movement of carbon among the atmosphere, oceans, soil, and living organisms.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is 6CO2 + 6H2O + energy → C6H12O6 + 6O2.

Front

What does 'LITHO' refer to?

Back

'LITHO' is short for Lithosphere, which is the rigid outer layer of the Earth.

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.

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

Explain the carbon cycle.

Back

The carbon cycle is the series of processes by which carbon compounds are interconverted in the environment, involving photosynthesis, respiration, decomposition, and combustion.

Front

What is the significance of the lithosphere?

Back

The lithosphere is significant as it includes the Earth's crust and upper mantle, providing the foundation for terrestrial ecosystems.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (C6H12O6) and oxygen (O2).
