Inquiry Skills
1. An animal is on the endangered list of endangered species. This animal is a
large vegetarian and lives in forests and grasslands. Based on this
information, what could you infer about a possible reason for the declining
population of this animal?
2. Look at the image of primary succession on page 228-229. Describe the
changes and stages. Predict how the land might continue to change.
3. Suppose the people in Town A conserve resources and avoid burning fossil
fuels. The people in Town B to the northwest burn lots of fossil fuels and
dump wastes into the river. How might the people in Town A be affected by
the actions of the people in Town B?
4. The plains of Africa, called the savanna, contain grasses, scattered trees, and
shrubs. The savanna is home to many kinds of grazing animals and the
predators that hunt them. It has a season of heavy rain. This is followed by a
dry season in which very little rain falls.
Different species of plant-eating animals on the savanna eat plants at
different heights. For example, gazelles eat grasses, black rhinos eat
shrubs, and giraffes feed on the tree leaves. Why do you think the
animals are adapted in this way?
Many savanna animals give birth only during the rainy season. Why
might this be so?
