What process is used by producers to make their own food?

What is the source of energy plants use to perform photosynthesis?
The source of energy is sunlight.
Chloroplasts Capture Sunlight.
True
What do we call organisms that make their own food using photosynthesis?
Producers
____________ is the green pigment in a chloroplast that absorbs light energy during the light reactions of photosynthesis.
Chlorophyll
A plant's ________ absorb water from the soil.
Roots
Light is the source of energy for photosynthesis.
Photosynthesis reactants include: ________ and _______.
Carbon Dioxide and water
Why is photosynthesis kind of like "backwards breathing"?
1. Plants can survive without it, while humans can't live without breathing
2. Plants take in carbon dioxide and release oxygen, while humans do the opposite
3.Plants use it to make energy, while people breathe to get rid of energy
2. Plants take in carbon dioxide and release oxygen, while humans do the opposite.
Xylem
What is the function of xylem?
1. To move water through a plant
2. To collect sunlight
3. To release waste oxygen
1. To move water through a plant
What gas do plants release into the air that is needed by animals?
Plants release oxygen into the air.
What are stomata and what do they do? (remember they look and act like a mouth!)
Stomata are small openings on the leaf that allow gases to pass into or out of the leaf.
How do forests help "balance out" human activities that harm the atmosphere?
1. By absorbing the Sun's energy, which prevents it from heating Earth
2. By producing chemicals that turn carbon dioxide into water vapor
3. By absorbing the carbon dioxide released by burning fossil fuels
3. By absorbing the carbon dioxide released by burning fossil fuels
light, glucose
Photosynthesis products are sugar and oxygen.
True
Foxes eat small animals to get energy. Where does the fox's energy originally come from?
1. The sun
2. Bunnies
3. Grass
1. The sun
