Ecological succession. Ecological succession, the process by which the structure of a biological community evolves over time. Two different types of successionâprimary and secondaryâhave been distinguished. Primary succession occurs in essentially lifeless areasâregions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier.
According to Georgia law: 1  ALL children under the age of 8 whose height is less than 57 inches must ride in the backseat of a car.  Children under the age of 8 are required to be in either a car seat or a booster seat suitable for their age and height.
The previous policy, from 2002, advised that it is safest for infants and toddlers to ride rear-facing up to the limits of the car seat, but it also cited age 12 months and 20 pounds as a minimum.
