Chemical Reactions
A change where new substances are formed
Chemical Reaction
Energy released in a reaction that feels warm
Exothermic reaction
The place where an organism lives.
An organism that makes its own food using sunlight.
Producer
Large pieces of Earth’s lithosphere that move over time.
Tectonic Plates
The starting materials in a reaction.
Reactants
Energy absorbed in a reaction that feels cold
Endothermic reaction
Living parts of an ecosystem.
An organism that eats other organisms.
Consumer
This boundary forms when two plates move away from each other.
Divergent boundary
The substances formed after a reaction
Products
A student mixes chemicals and the temperature of the container drops.
Endodermic reaction
Nonliving parts like water, sunlight, and temperature.
Abiotic Factors
A diagram showing feeding relationships in an ecosystem.
Food web
A mountain range forms when two continental plates collide.
Convergent Boundary
Color change, gas production, or temperature change are signs of this.
Chemical reaction occuring
What is an example of an exothermic reaction
(Hot hands)
A pond dries up and fish populations decrease.
Abiotic factors affecting organisms
If a predator is removed, prey populations increase.
There arent as many predators hunting them.
Scientists find identical fossils on two different continents.
Evidence of continetal drift
Where do the different atoms go during a chemical reaction?
They rearrange
chemical reaction in a sealed bag shows no mass loss.
Matter is being conserved ( atoms rearrange and arent destroyed
A species cannot survive when its environment changes too much.
Inability to adapt to habitat changes
Energy decreases as it moves up trophic levels. What percentage is passed on
%10
Ocean floor rocks are youngest near ridges and older farther away.
Seafloor spreading
