We want to deepen the understanding about how the diverse elements of a living eco-system are interconnected.

An ecosystem includes all the living things in a give area interacting with each other and also with their non-living environement. In a eco-system we can find four (4) components:
1) Abiotic substances: Mineral elements. Organic compounds. Water Physical matters, e.g., sunlight, wind, gaseous elements
2) Producers: all green plants and autotrophic bacteria
3) Consumers: insects, birds, cows, etc. and 
4) Decomposers and converters: microorganisms Go for a walk in your closest park and find one of each of these components.

What connections do these components have?

You can draw a small organigram in which the connecting lines represent the different relationships between the components
