Do all ecosystems have consumers?

The living organisms in an ecosystem can be described as producers, consumers and decomposers. … (All animals are consumers.) Decomposers break down dead matter – these may be bacteria or animals that feed off dead plants and animals. Inorganic matter is what non-living things are made from.

If there were no decomposers, some plants might die due to a shortage of important nutrients. … Some organisms could die, some could survive, and some could move to a new location.

What would happen in an ecosystem without decomposers?

Without decomposers, dead leaves, dead insects, and dead animals would pile up everywhere. … Thanks to decomposers, nutrients get added back to the soil or water, so the producers can use them to grow and reproduce. Most decomposers are microscopic organisms, including protozoa and bacteria.
