• Fermentation

• Transpiration

• Respiration

• Photosynthesis

What are the three conditions necessary for photosynthesis to occur?

• Sunlight, oxygen, and nitrogen

• Water, sunlight, and carbon dioxide

• Water, sunlight, and oxygen

• Water, carbon dioxide, and nitrogen

How do plants obtain the sunlight needed for photosynthesis?

• Through their roots

• Through chloroplasts containing chlorophyll

• Through their stems

• Through their flowers

What is the main purpose of respiration in living organisms?

• To produce food

• To release energy

• To create water

• To absorb sunlight

Which gas is taken in by animals during respiration?

• Hydrogen

• Nitrogen

• Oxygen

• Carbon dioxide

What is transpiration primarily responsible for in plants?

• Absorbing nutrients

• Releasing water vapor

• Creating chlorophyll

• Producing seeds

Where are stomata mainly found on a plant?

• On the stems

• On the roots

• On the flowers

• On the underside of leaves

What role do decomposers play in the ecosystem?

• They produce oxygen

• They break down dead matter

• They absorb sunlight

• They create food

Which of the following is NOT a decomposer?

• Bacteria

• Fungi

• Earthworms

• Mites

What is the difference between decomposers and agents of decomposition?

• Agents break down dead matter, while decomposers assist in the process

• There is no difference

• Both decomposers and agents produce food

• Decomposers break down dead matter, while agents assist in the process
