Cycles of Live

In this topic I learn many things like the decomposers help in the nitrogen cycle.

First I will explain what is a cycle a cycle is a process that have no begining and no end.

In the water cycle  they are things that help in this cycle like the sun, the trees. The sun help evaporating the water , the trees help by transpirating.
In the carbon cycle also the trees help by changing the carbon dioxide into oxigen.

living things and their envirment

The living thing or biotic and nonlivving things are found evrywhere . living things need non living things to survive.   the science that studies how living things an their envirorment interact isan e called ecology. Every living thing has a role or a niche,  an example of this is that every organism reproduce.

Examples of biotics factors:

animals

plants

fungie

algae

bacteria 

Example of abiotic factors.

mineral

rock

water

wind

summary #1

Enegy reasources are reasouces that can be use as energy example of energy that contaminate fossil fuel that do not contaminate wind solar energy water energy the energy can be use in many ways like seeing television using the cars evry thing now use enrgy. Brazil is the number one country dont contaminating they do not use fossil fuel they use somting that when the corn fermentaid something that can be use as energy for making that they need corn a special box without howls and bacterias.
