Insects are small, six-legged animals. There are many different insects, like bees, ants, wasps, butterflies, cockroaches, ladyb
ugs, fireflies, and termites. Other insects include houseflies, dragonflies, mosquitoes, grasshoppers, lice, crickets, fleas, and moths. The list goes on and on. In fact, it would take over 6,000 pages to print the scientific names of all insects on paper. Over 1.5 million species of animals have been named by scientists. Approximately 1 million of these are insects. Scientists discover 7,000 to 10,000 new species of insects each year. Some scientists believe that 1 million to 10 million species of insects are still undiscovered.
Insects live almost everywhere on Earth. They live in tropical jungles and cold snowy regions. They can be found high on mountains and in deserts below sea level. From caves to the sky, insects can be seen crawling or flying. The only place where few insects are found is the ocean.

Which of the following would be the best paragraph headings for the three paragraphs above?
A.
1. Bees, Ants, etc.
2. Insect Names
3. Earth and Ocean
B.
1. Insect Lists
2. Insect Scientists
3. Insect Lives
C.
1. Types of Insects
2. Numbers of Insects
3. Habitats of Insects
D.
1. Small Animals
2. Scientific Discoveries
The first paragraph discusses the various types of insects. The second paragraph discusses the numbers of insects. The third paragraph discusses the habitats of insects. Thus the correct outline would be 1. Types of Insects (paragraph 1), 2. Numbers of insects (paragraph 2) and, 3. Habitats of Insects (paragraph 3).
The organizing principles that are used in this paragraph are comparison and contrast; cause and effect. In the beginning, the author is giving the similarities and the differences between petroleum and coal, and moves on to talk about cause and effect in the end.
