    Natural forest

Answer

  1. Natural forest

Explanation:

The ecosystem is an interaction between living organism and their physical environment. The level of interactions and exchange of materials will explain the stability of an ecosystem.

More the interactions and greater the exchange of materials more will be the stability of an ecosystem. Thus, forests will be a stable ecosystem as compared to lakes, because of the more variety of organisms at each trophic level, which will result in very complex food webs.
