Science Checkpoint Stage 9: Photosynthesis and Respiration

All food chains begin with a...

• grass

• producer

• consumer

• decomposer

Plants produce their own food through...

• symbiosis

• photosynthesis

• genetics

• magic

What is a food chain?

• The flow of energy from one thing to another

• The way animals eat each other

• The way the sun makes everything

• How the plants grow

What is a consumer? 

• Organism that creates their own food.
• Organism that eats other organisms for energy

• Organism that eats other dead organisms

What might happen if salmon become endangered?

• Bears might have a hard time getting the energy they need.

• Bears would have an easier time finding food.

• There would be more bears in the wild.

• There would be less insects in the wild.

Where do plants get the energy for photosynthesis to take place?

• nutrients in the soil

• the sun

• chlorophyll

• bee pollination

What part of the plant soaks up water for photosynthesis?

• roots

• petals

• leaf

• stem

Where do the leaves and stems of plants get their green color from?

• glucose

• oxygen

• carbon dioxide

• chlorophyll

The openings that are found in the leaves of plants are called:

• Stomata

• Chlorophyll

• Xylem

• Chloroplast

What are the 3 key ingredients needed for photosynthesis

• glucose, oxygen, carbon dioxide
• carbon dioxide, water, glucose
• water, soil, sunlight
• sunlight, water, carbon dioxide
