More about the food chain

We need to clarify our previous post because we have learned more about the food chain.

The food chain has four parts as a pyramid.  The first level is the producers.  The second level is herbivores.  The third level is carnivores.  The final level is decomposers.  Decomposers are bacteria, fungus and worms.  When an animal eats part of a plant and leaves some, the decomposers break down the rest of the plant and make it into soil.

We learned that if part of the chain breaks, it affects the entire chain.

Science

Today in science, we talked about:

• the human body and about the nervous system.  Specifically, we learned that nerves are connected to the brain.
• ecosystems and what they are.  They are places where abiotic (non-living) and biotic (living) entities depend on each other.
• changes in our terrariums and aquariums, like the water in the aquarium decreasing and the plants in the terrariums grew.
• food chains.  A video said that the food chain is like a game with 4 levels that look likes a pyramid.   The first level consists of herbivores and where plants die and decompose.  The second and third levels include carnivores.  The fourth level includes worms, bacteria and bugs.
