Consumers, Producers and Decomposers

Today, the grade 4's talked about food chains.  We learned that there are different types of categories that organize the plants and animals in the world.  We saw how plants are producers and make the food for the rest of the planet.  (The plants get the energy from the sun.)  Next, we talked about First Consumers, who are animals that eat the plants.  Second Consumers eat the animals that eat the plants.  Third Consumers eat the animals that eat the animals that eat the plants!  Humans fit into all three categories because we are omnivores.

We also talked about what happens to the waste we have from left over food, for example, apple cores or banana peels.  We wanted to see just how this food decomposes in the earth.  We took some small pieces from our lunches that we thought would decompose and buried it in the small flower pots in the front of the school.  In one week, we will dig it up to see just how much has actually been broken down and decomposed.
