In any ecosystem a species can grow, reproduce and multiply only if they get food to eat and get energy.

The education that was provided in the colonies varied greatly depending on the region, the gender and the class of the people involved.
In the New England colonies, education was considered to be extremely important, and this usually had a heavy religious component. Most Puritans believed that education was a way to follow God's wishes, as it allowed people to read the Bible.
In the Middle Colonies, education was also considered important, but this was less organized than in New England. Most children were educated in community schools, which reflected the tight nature of the communities.
Finally, education in the South was heavily stratified. Wealthy landowners received an excellent education, while women were generally only able to read and write and perform basic math. Moreover, most slaves were not educated in any way. People who did receive education in the South generally did so through the use of private tutors, as communities were not as close and the distance between plantations was usually very large.
