hi me and Alek have task card six and we will be talking about things such as producers, consumers, respiration, decomposers and energy pyramids. This requires us to provide a definition of producers and write about what consumers do. The card also requires us to provide an equation for respiration for our peers to see. As well as consumers we have to say what decomposers do and describe what happens to energy as it moves through an energy pyramid.we also have to create an energy pyramid, including first level ( producer), second level ( first consumer ) etc.

Hey everyone

Shannon and i have got task card 5

its about decomposers.

it asks us to research the definition of a decomposer.

we also have to find out what self-sustaining means.

the third thing we have to do is answer two questions about the importance of decomposers in a food web and also to find out of an ecosystem can be self sustaining without a decomposer.

the last task we have to do is to create a flow matter diagram.

Ecosystem Earth

David and I have task card twelve which is about Ecosystem Earth, urban ecosystem, natural ecosystem, biotic and abiotic environmental factors. The main task is showing the differences between urban and natural systems, the differences between biotic and abiotic environment factors and then shows how these contribute and affect the ecosystem and the animals in natural ecosystem.

Carbon Cycle

Hi classmates!!

TASK CARD No. 10..(the carbon cycle)

The image above is a simple diagram of the carbon cycle...

ANIMALS IN THE CARBON CYCLE

Animals are a very important part of the carbon cycle.

The plants get carbon from the carbon dioxide in the air (as part of photosynthesis), animals then eat the plants and use the carbon to build their own tissues. After the animals die they decompose back into the earth and then help the plants to grow again, contributing to the carbon cycle.

CARBON IN THE AIR
There are two simple ways for carbon in plants to end up back in the air.
No.1: through respiration in plants (when the carbon is "breathed" out of the plant etc.)
No.2: when animals consume the plant, they then breathe out carbon dioxide back into the air.
The amount of carbon dioxide in the air affects the Earth's temperature in a major way. The more greenhouse gases we produce, the more carbon dioxide is in the air. And when there is lots of carbon dioxide in the air it contributes to global warming, therefore raising the Earth's temperature.
Carbon dioxide is the substance that we breathe out every day, it is everywhere around us even though we don't know it!
WHERE IS CARBON STORED
Carbon is stored within living and non-living things. But it it stored for the longest in the soil...
When plants die they decompose and become a part of the soil. They are stored here in the ground for long periods of time before it is transformed into fossil fuels or sometimes coal.
HUMANS AND THE CARBON CYCLE
Humans have disturbed the carbon cycle in two ways which have decreased the carbon dioxide in oceans and plants and added more carbon dioxide to the atmosphere.
If humans didn't exist the carbon cycle would suffer but it would still take place because there would still be other animals in the cycle.
Humans add unneccesary extra carbon dioxide to the atmosphere with greenhouse gases and through the use of machinery and cars. All the new technology of today and the future, certainly will not help the carbon cycle.

Watch for more updates on the carbon cycle :)

Task Card 11

hi every one Jack and i are doing task card 11 which is about habitats and enviroments.

Habitats are places where organisims live and coexist.

enviroments are habitats for habitats exist

2 of australias major enviroments are the oceans and the desert.

the first enviroment is the ocean. this huge body of water covers 71% of the worlds surface. this is a very large environment and holds home to thousands of habitats for marine life.

Deserts are almost the opposite as they hold little life except for drought resistant plants and reptilian life.

Hey guys,

Jacob and I have task card two which is all about food webs.

It asks us to create a food web of a river eco-system, explain the consequences of forcing an important part of the food chain to extinction and explain why so many trees are required to support just one lion. Above i have an example of a food web. It simple shows what feeds off what.

Hey Hey everyone!

Caragh and i have the task card five.

We are researching what a decomposer is.

So a decomposer is an animal or insect that

breaks down dead animals or plants.

We are finding out information on this statement:

natural ecosystms can be described as self-sustaining.

Also we have to find out a bit about the importance of
decomposers in a food web.
