Our Scientific Walk

 For this science unit we are doing Ecosystems. An ecosystem is an area with biotic and abiotic things like bugs, bacteria, animals, plants, rocks and many other things. There can also be scavengers like ravens that eats garbage and other dead animals. We went on a walk and saw how the when the enviroments change the living things will change which is called ecological succesion. We also saw how much the rocks change in colour from bioaccumulation.

Micro-organisms can break down dead animals into nothing which is call decomposers. The chemical process by which green plants synthesize organic compounds from carbon dioxide and water in the presence of sunlight to make food for itself is called photosynthesis. Everywhere we looked we saw places where life can exist this is called a Biosphere.

    How long do you think that it takes for decomposers to work? How long would it take to break down a dead animal in the environment? Do you think we can change that speed? Can we speed it up or slow it down? Why would we want to do that?
