Life Science A
It's where all energy in an ecosystem comes from.
What is the sun?
It's what scientists call a living thing.
What is an organism?
Anything that takes up space and has mass.
What is matter?
It is what makes up all matter.
What are atoms or molecules (particles)?
97% of the water on Earth is this type of water.
What is saltwater?
The process by which plants make their food from sunlight, carbon dioxide, and water.
What is photosynthesis?
All of the living and nonliving things in an area.
What is an ecosystem?
Color, shape, texture, and mass are all examples of this.
This type of change always produces a new substance.
What is a chemcial change?
The process of changing a gas to a liquid.
What is condensation?
It's the part of the food chain responsible for photosynthesis.
What is a producer?
An organism that eats other organisms.
What is a consumer?
Salt dissolving in water, peanut butter mixed with jelly, and a candy bar melting are all examples of this.
What are physical changes?
Food digesting, fireworks exploding, and iron rusting are all examples of this.
What are chemical changes?
Water in any form falling to the Earth.
What is precipitation?
This is the type of food plants make during photosynthesis.
What is sugar or glucose?
In this food chain this organism gets its energy from the bird.
Grass → Caterpillar → Bird → Snake
What is the snake?
Mixing walt and water is an example of this type of change.
What is a physical change?
A gas forms and heat is produced when two substances are mixed showing this type of change.
What is a chemical change?
This is added to or taken away from matter for it to change state.
What is energy (heat)?
This is the other product of photosynthesis.
What is oxygen?
This is not a complete food chain because it is missing this
What is a decomposer?
Water in a bowl has a mass of 25 ml. After it is frozen its mass still measures 25 ml showing this.
What is conservation of matter (mass)?
The theory that the amount of matter (or mass) stays the same no matter what type of change occurs.
What is conservation of matter (mass)?
Living things make up this sphere.
What is the biosphere?
