Make a list of all the different types of organisms, including plant, humans, insects, and so on that you see near your home.

Wherever you look there is always a ecosystem. The organisms that are near your house are anything from trees, grass, flowers, etc. There is also dirt, it may look like nothing but there tiny microscopic organisms that live there. Insects are highly involved in an ecosystem, you got spiders, ants, bees, flies, worms and etc. Basically anything you can think of is in an ecosystem. 
 
Hope this helps:)
