Food Chains

The Food Chain

An ecosystem is a living community which depends on each member and its surrounding environment. 

Every participant in an ecosystem has an important part to play and if one becomes more dominant than the others, the ecosystem can develop problems.

We'll start with the producers. These are living things which take the non living matter from the environment, such as minerals and gases and uses them to support life.

Green plants are considered producers and the are at the beginning of the food chain.

Next are the consumers. These living things need the producers to be their food. 

Animals who eat plants are called herbivores. They are considered consumers and are next in the food chain. 

Animals who eat other animals are called carnivores. They also considered consumers and are a link farther along on the food chain since they need the herbivores for their food.

Animals and people who eat both animals and plants are called omnivores, and they are also part of the consumer piece of the ecosystem.

Finally, the last part of the ecosystem is the decomposers. These are the living things which feed off dead plants and animals and reduce their remains to minerals and gases again. Examples are fungi, like mushrooms, and bacteria.

Pollution isn't good.

Soon it will be the end

and we won't have a chance
 to do it all over again.
Earth is our home.
Let's take care of our world.
A time when Earth wasn't polluted
seems like a blur.
When will we ever learn?
I see fields of flowers
but soon they will be dying.
I don't know about you
but I am trying
to save our home.
So I'm writing this poem.
The world was once blue
but now it is grey.
Soon all happiness will fade.
Let's treat our home with love
so that He will start smiling
on his home from up above.
It was once  happiness,
it was once bright,
but now there is no more light.
The world is dark as night.
Let's try to make it white,alive
Let's fight.
