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.
Your child is ready for a booster seat when he grows too tall for a forward-facing child restraint. You can check the shoulder markers on your childâs forward-facing seat to ensure he has outgrown it. One of the most common mistakes parents make with car seats is moving their child to the next restraint too early. Legally, your child can sit in a booster seat from his fourth birthday.
