What is WEATHER?
Day-to-day conditions in Earth’s
atmosphere, such as
“sunny and humid,” describe

What is RESOURCE PARTITIONING?
In Madagascar, several species of
lemur eat bamboo, but each species specializes
in one part of the bamboo—
one species eats mature bamboo stalks, one
species eats bamboo
shoots, and one species eats
leaves. This is an example of
