Detailed explanation-1: -Species diversity hurts ecological succession. Explanation: Species diversity does not contribute for ecological succession. The diversity among the species is high at pioneer community. However as time passed competition and interaction causes a significant drop in species diversity.

Detailed explanation-2: -Species diversity commonly increases with succession and this relationship is an important justification for conserving large areas of old-growth habitats. However, species with different ecological roles respond differently to succession.

Detailed explanation-3: -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. Ecological succession is a fundamental concept in ecology.

Detailed explanation-4: -Nothing remains the same and habitats are constantly changing. In the ecological succession the biomass overall decreases. There are two main types of succession, primary and secondary. So the correct option is ‘Species diversity, biomass increases’.

Detailed explanation-5: -Answer: D it is a random process, The process through which the mix of species and environment in a given region changes over time is known as ecological succession.
