Ecosystems
All the living and nonliving things interacting in a particular area.
Ecosystem
Is a rock biotic or abiotic?
Abiotic
An organism that can make its own energy-storage molecules, such as glucose.
Producer
A molecule that an organism can use to release the energy it needs to survive.
Energy-storage molecule
What source of energy do plants use during photosynthesis?
Sunlight
A set of interacting parts forming a complex whole.
System
Is a living tree biotic or abiotic?
Biotic
An organism that needs to eat in order to get energy-storage molecules, such as starch and fat.
Consumer
A molecule made of carbon and oxygen atoms.
Carbon dioxide
Name one substance plants use during photosynthesis.
Carbon dioxide or water
A closed ecosystem made by humans.
Biodome
Material that makes up the nonliving parts of an ecosystem, such as air, water, and rocks.
Abiotic Matter
Is a green plant a producer or a consumer?
Producer
Name one example of an energy-storage molecule.
Glucose, starch, or fat
What energy-storage molecule is made during photosynthesis?
Glucose
A pond has fish, plants, water, rocks, sunlight, and insects. What word describes all of these things interacting together?
Ecosystem
Material that makes up the living and dead organisms in an ecosystem.
Biotic matter
A rabbit eats grass to get energy. Is the rabbit a producer or consumer?
Consumer
A type of atom—a tiny piece—that makes up molecules such as carbon dioxide and energy-storage molecules.
Carbon
The process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose.
Photosynthesis
Why can an ecosystem be considered a system?
Because it has different parts that interact and work together as a whole.
A dead leaf falls into a pond. Is the dead leaf biotic or abiotic matter?
Biotic matter, because it came from a living organism.
How does a plant get energy-storage molecules differently from a rabbit?
A plant makes its own energy-storage molecules, while a rabbit gets them by eating.
What is the difference between a carbon atom and a carbon dioxide molecule?
Carbon is one type of atom. Carbon dioxide is a molecule made of carbon and oxygen atoms.
