Problem: Billy had a pet turtle that he took good care of, everyday. His turtle's name was Tumble. Tumble liked to walk around outside in the garden and dig small holes to sleep in. Billy loved Tumble and would visit him outside when he got home from school. Tumble's favorite food was oatmeal. So, every day after school, Billy would make Tumble a big bowl of oatmeal and take it outside for Tumble to enjoy. Tumble would see Billy and walk up to him as fast as a turtle can go. Billy would put the bowl down and wait for Tumble to come up to the bowl to eat from it. When Tumble reached the bowl, he put his nose on it. But, the oatmeal was too hot to eat. Billy reached down and blew on the hot oatmeal, to cool it down for Tumble to eat. Once the oatmeal was cool enough, Tumble could dig in and eat his big bowl of oatmeal. Billy loved to watch as Tumble ate his bowl of oatmeal, because Billy took good care of Tumble, everyday.

Question: "What would happen if the oatmeal was too hot to eat?"

Answer: "Tumble would burn himself"
Answer: no

Problem: Federal health authorities Monday added 58 types of cancer to the list of covered illnesses for people who were exposed to toxins at the site of the World Trade Center in the aftermath of the September 11 attacks.

Problem: Living things need non-living matter as well as energy. What do you think matter is used for? One thing is to build bodies. They also need it to carry out the processes of life. Any non-living matter that living things need is called a nutrient. Carbon and nitrogen are examples of nutrients. Unlike energy, matter is recycled in ecosystems. You can see how in Figure 3.11. Decomposers release nutrients when they break down dead organisms. The nutrients are taken up by plants through their roots. The nutrients pass to primary consumers when they eat the plants. The nutrients pass to higher level consumers when they eat lower level consumers. When living things die, the cycle repeats.

Question: "Name an example of a nutrient and what it can do."

Answer: "Carbon"
Answer:
no
