Photosynthesis Power
What gas do plants take in from the air for photosynthesis?
Carbon Dioxide (CO2)
What do we call an organism that makes its own food?
Producer
What is an ecosystem?
All the living and nonliving things in an environment and how they interact.
Living things are also called what?
Organisms
When plants make food, where does the matter in the sugar come from?
From carbon dioxide and water.
What do plants release as a waste product of photosynthesis?
Oxygen
What do we call an organism that eats other organisms to get energy?
Consumer
What is a habitat?
The place where an organism lives and finds what it needs to survive.
A group of the same kind of organism living together is a what?
Population
How does matter move from plants to animals?
Animals eat plants and take in the matter stored in them.
What are the three things plants need for photosynthesis?
Sunlight, water, carbon dioxide (CO2)
Why do animals need food?
To get matter and energy for growth, repair, and survival.
What do we call an animal that hunts other animals for food?
Predator
All the populations living together in an area make up a what?
Community
What happens to matter in an ecosystem when organisms release waste or die?
It returns to the environment to be reused by other organisms.
What is the name of the process plants use to make their own food?
Photosynthesis
Where does all the energy in food originally come from?
The Sun
What do we call the role an organism plays in its environment?
Niche
What do we call the animals that are eaten by predators?
Prey
Explain how energy and matter move differently in an ecosystem.
Energy flows one way (from Sun to organisms), but matter cycles through living and nonliving parts.
Explain how energy from the sun becomes stored in plant matter.
Light energy from the sun is changed into energy (sugar) through photosynthesis.
Describe how energy flows through a food chain.
Energy moves from the Sun → producers → consumers → decomposers.
How can humans change an organism’s niche or habitat?
By clearing land, polluting, or changing available resources.
What is the process that turns sunlight into sugar and oxygen?
Photosynthesis
Trace the path of matter and energy from the Sun to a hawk.
Sun → grass (photosynthesis) → mouse (eats grass) → hawk (eats mouse).
