A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called
Natural Selection
Selective Breeding
Random mutations
Variations in a species
Why might it be helpful for a species to have a lot of variations?
They can't be seen by predators
If the environment changes, they might be better able to adapt
It is helpful in asexual reproduction
They don't recognize each other
The purpose of selective breeding is to
Get bigger animals and plants
Get smaller animals and plants
Create animals and plants with desirable traits
Create animals and plants with bad traits

breed two cows.
breed a female cow with a lot of muscle and a male cow with a lot of muscle.
breed the biggest cow and the smallest bull

What is true about sustainability?
Having a small number of species increases biodiversity
Sustainability is how organisms change over time
Sustainability is how much rainfall and sunlight an ecosystem receives
