On primary succession newly exposed or newly formed rock is colonized by living things for the first time. And in secondary succession an area that was previously occupied by living things
The density of the clay plate is 1970 kg m⁻³
the problem we are dealing with is related to density, which is the mass of a unit volume of a material substance. The formula for calculating density is d = M/V, where d is density, M is mass, and V is volume. Since we are provided with the volume of the clay plate which is 30.0cubic centimeters and the mass of the plate which is 59.1grams
so,V= 30 cm⁻³=3x 10-5 m and M= 59.1grams= 0.0591 kg
Therefore, the density of the plate is: M/V
=>d = 1970 kg m⁻³
