OBJECTIVE FORESTRY

Detailed explanation-1: -Ecological succession is the process by which the mix of species and habitat in an area changes over time. Gradually, these communities replace one another until a “climax community”-like a mature forest-is reached, or until a disturbance, like a fire, occurs.

Detailed explanation-2: -In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed-disrupted-then recolonized following the disturbance.

Detailed explanation-3: -Explanation: Species diversity does not contribute for ecological succession.

Detailed explanation-4: -Explanation: Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a wildfire. The newly created volcanic island has no previous life, and is made of rock, devoid of soil.
