Summary:
        The energy pyramid and the food chain relate because in a food chain you have to have the parts of the energy pyramid. There are usually decomposes in a food chain and those are things like mushrooms and bacteria. There are producers which are things that are able to make their own food and don't have to eat other organisms like plants. Consumers that are the things that need to eat something to make their energy like how we are consumers and so are mice and other animals. When you are on the top of a food chain that means that you are only a predator and you are not prey to other animals. Humans are at the top of the food chain now but it wasn't always that way. The nitrogen cycle and the carbon cycle are two cycles that start as a gas and end as a gas.

S&EP: SP3: Planning and carrying out investigations
        On gizmos to investigate and experiment to see what happens in a food chain when you change different parts. Sometimes we might make a diseased animal that was sick or we might take away a certain amount of the animals. We would sometimes predict what we thought was going to happen and then we would test it out to see what actually happened. As well as the gizmos we played a board game of the carbon cycle and the nitrogen cycle. Some things that happened to me is I was in an animal and then it disposed, then I went to the surface water after I dissolved. a plant needed my nutrients to it took me, then the plant died then I decomposed. There was a forest fire so I went to the atmosphere,etc.

XCC: Cause and effect
        In the food chain every animal depends on another animal to be healthy and for them to have a large population. In the food chain if you did certain things like if you made it so that the producers all died then the rest of the food chain would die because the consumers need the producers to survive. In a food chain when you wipe out a animal or plant it would effect everything else as well and the population of things would go wild. The food chain might seem sad but it is very important to make sure all of the animals stay at a steady population and they don't over populate or go extinct. The food chain can be very delicate but sometimes with major disturbances the populations will go wild but eventually even out.
