What 3 things do plants need to survive?
Sunlight, water, air
What is the main source of energy for Earth?
The sun
What is a producer?
An organism that makes its own food (plants)
What is matter?
Anything that has mass and takes up space
What does the digestive system do?
Breaks down food
Do plants need soil to grow?
No
What is photosynthesis?
The process plants use to make food using sunlight
Give an example of a consumer.
Animal (ex: snail, human)
What is matter made of?
Tiny particles
What does the circulatory system do?
Transports materials through the body
Where does most of a plant’s mass come from?
Air (carbon dioxide) and water
What do plants produce during photosynthesis?
Sugar (glucose) and oxygen
What do decomposers do?
Break down dead matter and recycle nutrients
Give an example of matter cycling in ecosystems.
Carbon dioxide → plant → animal → environment
How are body systems similar?
They work together to keep the body functioning
What gas do plants take in from the air?
Carbon dioxide
What does chlorophyll do?
Absorbs sunlight
In what direction does energy flow?
Sun → plants → animals
What gas is released by plants?
Oxygen
What do our bodies use energy from food for?
Growth, repair, movement, warmth
Why is sunlight important to plants?
It provides energy for making food
What type of energy change happens in photosynthesis?
Light energy → chemical energy
What happens if producers disappear?
The whole ecosystem collapses (no energy source)
Why doesn’t matter disappear?
It is conserved and recycled
Law of Conservation of Matter
Why must body systems work together?
To keep the organism alive and functioning
