L1.4 Sunlight and Life Quiz

Why is there not much life at the bottom of the lake?

• There is too much sunlight.

• There is not enough sunlight.

• There is too much oxygen.

• There is too much algae.

Answer explanation

The correct answer is 'There is not enough sunlight.' At the bottom of a lake, sunlight penetration is limited, which reduces photosynthesis and consequently limits the amount of life that can thrive there.

What do energy storage molecules include?

• Water and oxygen

• Glucose, starch, and fat

• Carbon dioxide and nitrogen

• Salt and minerals

Answer explanation

Energy storage molecules include glucose, starch, and fat, which store energy for later use in living organisms. The other options do not serve this function.

What process do producers use to make energy storage molecules?

• Respiration

• Evaporation

• Photosynthesis

• Condensation

Answer explanation

Producers use photosynthesis to convert sunlight, carbon dioxide, and water into glucose and oxygen. The glucose serves as an energy storage molecule, making photosynthesis the correct process for energy storage.

What do producers take in from the air to make glucose?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

Answer explanation

Producers, like plants, take in carbon dioxide from the air during photosynthesis. They use it, along with sunlight and water, to produce glucose, which is essential for their energy and growth.

Where does the process of photosynthesis take place?

• In the roots of plants

• In the chloroplasts of plant cells

• In the stems of plants

• In the flowers of plants

Answer explanation

Photosynthesis occurs in the chloroplasts of plant cells, where chlorophyll captures sunlight to convert carbon dioxide and water into glucose and oxygen, making this the correct answer.

What do producers need in order to perform photosynthesis?

• Water

• Soil

• Sunlight

• Wind

Answer explanation

Producers, like plants, need sunlight to perform photosynthesis. Sunlight provides the energy required to convert carbon dioxide and water into glucose and oxygen, making it essential for this process.

What role do consumers play in the ecosystem?

• They produce energy storage molecules

• They eat producers to get energy storage molecules

• They create sunlight

• They turn carbon into oxygen

Answer explanation

Consumers play a vital role in the ecosystem by eating producers, which are organisms that create energy storage molecules through photosynthesis. This allows consumers to obtain the energy they need to survive.

What happens in an ecosystem that gets lots of sunlight?

• It supports fewer organisms

• It supports more organisms

• It becomes a desert

• It stops photosynthesis

Answer explanation

An ecosystem that receives lots of sunlight typically has abundant energy for photosynthesis, which supports more plants and, consequently, more organisms. This leads to a diverse and thriving ecosystem.
