Summary#3 Food web and Food Chain

There are two types of producers
Protist because the two have chlorophill.

Food Chain

Food Web

There are also consumers

Some are Carnivores. That means that only eat meat.
Some others are omnivores. And that means that can eat plants and meat.

And also there are descomposers.

Summary#1 Energy Resources

Alternative energy source, geothermal energy and biomass are examples of energy resources.



Mass=Amount of matter.

Alternative energy

Here are some examples of natural alternative energy sources.


Brasil is the country #1 because is one of the only contries that use fuel make of corn.
