Competition becomes more important as the number of individuals INCREASES or the availability of resourcesDECREASES.
Plants and animals may compete over _____
resources

EVENLY OR UNEVENLY distributed around the world.
UNEVENLY
What is it called when a molecule contains two or more elements?
Compound
How many of atoms each element exist in this chemical formula:
2Na2SO4
Na:
S:
O:
Na: 4
S: 2
O: 8
How does competition limit the amount of individuals in populations?
If there is more competition, organisms will have to work harder for resources and not all have the resources they need to survive.
In a forest habitat, how are the populations of rabbits and foxes dependent on each other?
Fox are predators and rabbit are prey
If the rabbit population goes down, the fox population would also go down. If the rabbits increased, so would the fox.
