Question

Students read the following information about photosynthesis in their science textbook:

Plants use photosynthesis to make food
Animals get their food from plants
Photosynthesis produces a compound needed for respiration
The students want to build a simple model to represent photosynthesis in plants. They start with the materials shown below that they cut out of paper and label.

All animals eat food to obtain matter and energy. The cycling of matter and energy is driven by photosynthesis. Select the THREE statements that describe how all food comes from a process driven by photosynthesis.


Plants release oxygen during photosynthesis.


Plants use energy from the Sun to make sugars.


Some plants conserve water when exposed to heat.


Some animals eat plant-eating animals for energy.


Some animals eat plant matter for energy.


Animals use energy from the Sun to keep warm.

Answer 1

- Plants use energy from the Sun to make sugars.
- Some animals eat plant matter for energy.
- Some animals eat plant-eating animals for energy.

Reason: Photosynthesis (plants using sunlight to make sugars) produces the primary food/biomass that directly feeds herbivores and, indirectly, carnivores.
