Answer:
Human disturbance is constantly creating habitats. Plants and animals will recolonise these habitats and together with the non-biological part of the environment form a new ecosystem. These colonising species have an impact on the environment themselves and so the ecosystem will continue to change and develop.
Step-by-step explanation:
The ecosystem, or ecological system, is considered to be a unit of biological organization made up of all of the organisms in a given area, interacting with the physical enviroment so that a flow of energy leads to characteristic trophic structures and material cycles within the system.
