evolutionary succession

pioneer succession

secondary succession

primary succession

Answer 1

Secondary succession

Answer 2

Secondary succession takes place where an ecosystem already exists. An ecosystem is made from various plants, animals and life support processes and mechanisms.

Step-by-step explanation:

• In an already existing ecosystem, plant and animal species already exist and have adapted to live in the ecosystem.

• It is these plants and animals that evolve with time and make changes to their body structures to survive in the ecosystem.

• The animal and plant life in an existing ecosystem is also able to produce offspring that can easily survive and further evolve in the ecosystem thereby ensuring that the species already found in the ecosystem exist for a long time.
