Plant needs
In Every Tree for Itself, why would you die?
You did not grab enough water and air sticks.
Animals are what?
Consumers
Where do you get energy from?
The sun
What is an ecosystem?
An ecosystem is made up of living organisms (like animals, plants, and bugs) in an area with all of the non-living organisms (like water, dirt, rocks, and the sun).
What is a chemical change?
any change that creates something new.
Where do we get energy from?
The sun!
What is makes something a producer?
a plant. A producer makes it own food with photosynthesis.
What does an arrow in a model show?
The arrows show the movement of matter in an ecosystem.
If a first consumer is introduced into an ecosystem, what would happen to a producer?
The producer would stay alive more because there is less hunting them.
Describe these two substances: wood shavings and baking soda. Pick 2
a. they are solids
b. they are a solid and a liquid
c. they are white and foamy
d. they are white and tan
What do plants get their matter from? I'm thinking of two. Think of the labs we did at the beginning of the module.
water and air
What is a food web?
multiple food chains that cross between each other
Does a bear get energy directly from the sun?
No, It has to eat something to gain that animals energy. That animal would either eat a plant or another animal. If it eats a plant the plant gets the energy directly from the sun.
Would an ecosystem survive if all their plants died?
No, they would have no way of getting energy or matter to be able to stay alive.
What do air particles look like?
Particles of matter have space between them and move quickly past each other.
Why would a plant die?
The plant would die because it doesn't get enough matter (from air, water, and soil), energy (from the sun), or something eats it.
What is a consumer?
Consumers are animals that each something else. They have to eat something to be able to survive.
What does energy help animals do?
Grow, hunt, repair and injury, or/ and stay warm.
The herbivores will have a harder time staying alive. The producers will have less hunting them, so they will have a lot more producers.
Eventually the carnivores will have less too eat because they have eaten all of the herbivores and they will die as well.
To have a fair test, which variables are most important to keep the same during different experiments? Pick 2
a. starting temperature of substances
b. Starting color of substance
c. final temperature of each substance
d. Starting amount of substances in the micture
A, D
depends on answer
Soil
Bear
Sun
Algae
Air
Fish
Water
Mushrooms

If an animal dies of a natural cause, what happened to its matter and energy?
It gets taken by the decomposer and the matter is brought back to the soil.
Identify 3 questions that could help identify if a chemical change has occurred during the experiment?
a. Does the color change?
b. Are there bubbles in the beaker?
c. Does a mixture form?
d. Does the temperature change?
