3-Photosynthesis and Energy Flow Review

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the main reactants of photosynthesis?

Back

The main reactants of photosynthesis are carbon dioxide (CO2) and water (H2O).

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is glucose (C6H12O6), which serves as energy for the plant.

Front

What role does sunlight play in photosynthesis?

Back

Sunlight provides the energy needed for photosynthesis to occur, allowing plants to convert carbon dioxide and water into glucose.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to facilitate photosynthesis.

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among organisms in an ecosystem, showing how energy and nutrients flow through the system.

Front

What is a decomposer?

Back

A decomposer is an organism, such as bacteria or fungi, that breaks down dead organic material, returning nutrients to the ecosystem.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the air through small openings in their leaves called stomata.

Front

What is the difference between a producer and a consumer?

Back

Producers are organisms that create their own food through photosynthesis (e.g., plants), while consumers are organisms that eat other organisms for energy (e.g., animals).

Front

What is the significance of photosynthesis in an ecosystem?

Back

Photosynthesis is crucial for ecosystems as it produces oxygen and organic matter, forming the base of the food chain.
