When animals eat food, they take in the body molecules of plants or other animals. Why is this done?

• They use them to build and grow their bodies and to release energy.

• They use them to build more food.

• They are not used for anything.

Which statement best describes how the matter is transferred between decomposers and plants?

• Decomposers are the top of the food chain. Matter and energy from decomposers are released into the ecosystem.

• Decomposers break down organisms and return nutrients to the soil. Plants need those nutrients to survive.

• Decomposers transfer matter from the air to the soil. The plants consume that matter for energy

• Plants are producers. They use energy from the sun to grow.

The Australian ecosystem has open spaces with hills covered with plants, such as grass and trees. One animal in this ecosystem is the kangaroo, which is an herbivore.  Kangaroos are large marsupials found only in Australia.
British settlers began colonizing Australia in the late 1700s. In 1859, 24 European rabbits were brought to Australia to make new British settlers feel more at home.  The feral, or wild rabbits which grew strong and reproduced rapidly, competed with the kangaroos for food and damaged the ecosystem. 
 In 1950, with approximately 600 million rabbits in Australia, scientists decided to try to lower the number of rabbits by releasing a disease into their environment. The disease killed many of the rabbits, but the dead rabbits created additional problems for the environment. Although there were many dead rabbits, eventually decomposers cleaned them up.

Which TWO ways do European rabbits and kangaroos interact with the Australian environment? 

• Rabbits and kangaroos obtain air and water from the environment.

• Rabbits and kangaroos interact with the Australian environment by providing food for plants

• Rabbits and kangaroos get energy from eating other animals.

• Rabbits and kangaroos meet their needs in their environment by eating plants for food.
