SHORT ANSWER
57. Answers will vary. Sample answer: All living things are composed of one or more cells. They all sense
change in their environment and have the ability to respond to change. All living things reproduce organisms
similar to themselves. All living things have DNA. They all use energy. They all grow and develop during
periods of their lives.
58. Apple trees have the six characteristics of living things: they have cells, they sense and respond to change,
they have DNA, they can reproduce, they use energy, and they grow.
59. Growth is an increase in size. Development is a change in the form of an organism that happens as it grows.
60. producer: plants; consumer: animals; decomposer: fungi

Species A through I would all share the same first word in their scientific names. For example, if they were all
cats, their scientific names would all begin with Felis followed by a unique species name.
65. I and J are on different sides of the first big branch. This means they are in distantly-related groups. I and A
are in the same group, so they are more closely related than I and J.
