Answer:
Ecosystems are closed systems.
Explanation:
Ecosystems are the open systems as there is exchange of heat with the surroundings. The solar energy enters the ecosystems and part of it is trapped by photosynthetic organisms.
The solar energy is transformed into the chemical energy of organic nutrients by the process of photosynthesis. The part of the energy released by breakdown of these nutrients is used by organisms to perform vital functions while rest of it is lost to space in the form of heat.
Since there is exchange of energy with their surroundings, ecosystems are open systems.
