10. What is an ecosystem? Picture a tiny world inside the Earth.
This smaller world of ecosystem has living things (plants and animals) which interact with non-living elements (water, rocks, soil and temperature).
An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter. All ecosystems require energy from an external source, usually the sun.
