What is the difference between autotrophs and heterotrophs?

Back

Autotrophs produce their own food through processes like photosynthesis, while heterotrophs obtain food by consuming other living or once-living things.

What is the main source of energy for all life on Earth?

Back

The sun.

Front

What are the reactants of photosynthesis?

Back

Carbon dioxide and water.

Front

Why do most plants appear green?

Back

Because chlorophyll reflects green light.

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 role does chlorophyll play in photosynthesis?

Back

Chlorophyll is the pigment that absorbs light energy, primarily from the sun, which is necessary for photosynthesis.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the significance of photosynthesis in the ecosystem?

Back

Photosynthesis is crucial for producing oxygen and organic compounds that serve as food for heterotrophs, thus supporting the food chain.

Front

What are the products of photosynthesis?

Back

Glucose and oxygen.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants absorb carbon dioxide from the atmosphere through small openings in their leaves called stomata.
