Which characteristic do immature ecosystems have?

Question

Quizplus · Accepted Answer

This is because they are in the initial stages of development and have not yet developed the complex interactions seen in more mature ecosystems. In these early stages, there are usually a few dominant species that are well adapted to the often harsh and less stable conditions. These species tend to be generalists that can exploit the available resources without the need for specialized niches or interactions. As the ecosystem matures, it tends to increase in complexity, including the development of more intricate food webs, higher species diversity (b), more specialized niches (c), and an increase in the number and types of decomposers (d). However, these characteristics are more indicative of mature ecosystems rather than immature ones.
