*****Once upon a time, a farmer went to a market and purchased a fox, a goose, and a bag of beans. On his way home, the farmer came to the bank of a river and rented a boat. But crossing the river by boat, the farmer could carry only himself and a single one of his purchases: the fox, the goose, or the bag of beans.
If left unattended together, the fox would prey on the goose and the goose would eat the beans.
The farmer's challenge was to carry himself and his purchases to the far bank of the river, leaving each purchase intact. How did he do it?
What is:
1. Take the Goose over
2. Return
3. Take the beans over
4. Return with the goose
5. Take the fox over
6. Return
7. Take goose over

this term describes lichen and moss that break down rock into soil during primary succession.
What is pioneer species?
400
Decomposers that extract energy from detritus.
What are bacteria and fungi?
400
This is an example of evidence that shows missing links between more recent and previous species
What is transitional species?
400
this explains how plants become resistant to herbicides
What is mutation and natural selection? OR what is what happens when a mutation arises, allowing the plant to live despite the presence of herbicide, and gets passed on?

In order to take advantage of whatever rains fall, many desert plants have extensive, shallow root systems. To prevent seedlings or plants from sending their roots into the area staked out by an established plants, those established plants may leach toxic chemicals into the soil to kill surrounding seedlings.
What is Competition?
500
Name one disturbance that could cause a primary succession and one that could cause a secondary succession.
What is volcano, glacier, ect for primary?
What is flood, fire, ect for secondary?

A fossil is a preserved remain of an organism. What can scientists learn by comparing fossils of the same organism found in different strata (layers) of rock?
What are evolutionary changes in organisms over time?
500
a slight difference in a trait of members of species that may provide an advantage to survive or reproduce depending on environmental conditions
what is variation?
