Explanation writing

Since last term , Te Ngahere have been working on a explanation about about ecosystems. Our WALT was to use the correct structure for an explanation. In our writing we had to include producers , consumers , decomposers and inorganic matters. I think I did pretty good because I could explain what each thing did and I was very descriptive. Next time I think I could finish my writing a lot quicker.

What is a Ecosystem

An ecosystem is like a type of cycle that uses non-living and living things

like  producers , consumers , Inorganic matter and a decomposer.  

In a marine ecosystem it usually contains , sea life, plants , water , sand and bacteria.
These all make up a healthy ecosystem .

What is inorganic matter?  Inorganic matter is a non-living thing like water , sand and
rocks. All of these things are not alive and are non-living. They all help the ecosystem
in different ways. Water helps plants grow and helps fish breathe. Rocks also help by
holding down the plants at the bottom of the ocean , the roots of the plants are holding
on to the bottom of the rocks that holds it down in the ocean.

What does organic matter mean? Organic matter means living ,  something that is alive.
It's the opposite meaning for inorganic matter a non-living thing. For example a fish is
an organic matter because it can move around and swim from place to place but water
can’t.

What are producers? Producers are living things and they use sunlight to grow and then
when the consumers eat the producers they get energy  to move and stay alive , but their
life doesn't last long.. For example : One consumer eats the producer , then the second
consumer eats the first , then its start off the second stage of the ecosystem.

What are consumers? Consumers are living things that eat the producers to get energy
in order to stay alive. For example : after one consumer eats the producer another
consumer will come and eat the first consumer. Consumers hold the ecosystem together
by feeding off the producers then carrying the cycle on until the stage of decomposers.

What is a decomposers? A decomposer also known as fungi , breaks down dead matter
that is then turned into bacteria. Then decomposers release nutrients like carbon and
nitrogen back into the environment. These nutrients are then recycled back into the
ecosystem so that producers can use them.   

An ecosystem is very fragile and can’t cope with a very big change within the cycle.
If one of the consumers stop working if could affect the whole ecosystem ,and then
it would break up then the ecosystem would be unbalanced and would have to restart.
When it is unbalanced producers would stop growing , consumers would overfill the
ocean , decomposers won’t break down dead matter so all of these problems would
break the ecosystem.
