For thousands of years, people have found fossils. The fossils caused curiosity about Earths past. How did these organisms live? What type of world did they live in? Fossils can tell us a lot about Earths history. In ancient times, fossils inspired myths and stories. These stories included tales of monsters and other incredible creatures. What type of creature do you know that could inspire such stories? Of course, dinosaur fossils were once mistaken for dragons bones. Two thousand years ago, people discovered fossils in China. At the time, they were thought to be dragon bones. We know now that these were not bones, but fossils. So what is the difference?

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: "What do living things use non living matter for?"

Answer: "Build bodies"

Response: yes

Charlie Mershone had no difficulty in securing his release when Parker came on duty at six o'clock. He called up a cab and went at once to his rooms at the Bruxtelle; and Fogerty followed him. While he discarded his dress-coat, took a bath and donned his walking suit Mershone was in a brown study. Hours ago Louise had been safely landed at the East Orange house and placed in the care of old Madame Cerise, who would guard her like an ogre. There was no immediate need of his hastening after her, and his arrest and the discovery of half his plot had seriously disturbed him. This young man was no novice in intrigue, nor even in crime. Arguing from his own stand-point he realized that the friends of Louise were by this time using every endeavor to locate her. They would not succeed in this, he was positive. His plot had been so audacious and all clews so cleverly destroyed or covered up that the most skillful detective, knowing he had abducted the girl; would be completely baffled in an attempt to find her.

Question: "What was Charlie wearing at six o'clock?"

Answer: "He wore a walking suit"

Response: no
