I have learned alot about ecosystems.One thing i have learned about them is that they are needed to keep the balence of nature.All ecosystems have producers,consumers and decomposers.Also they have biotic and abiotic parts.Interdependence means that things depend on each other.Balance is important because is there were too many of one thing they would dominate that area and some things might go extinct

Ecosystems have to have living and nonliving things. All ecosytems need producers, consumers, and decomposers. All organisms are interdependent. Interdependence is organisms depending on each other. Organisms need each other for many different things. In an ecosystem balance is very important. Balance is important because if more organisms take up more space then other organisms eventually die out. If all the organisms die out then the ecosystem eventually dies out.

I learned that living and nonliving live in their own enviornment.They have Producers,consumers,and decomposers.Interdependence is how animals depend on each other.Blance is important in an ecosystem because each animal needs to be safe or they will die and get eaten by other animals,and then they will never be alive again.
