plants and animals. He further divided the
animals into three smaller subgroups: land
dwellers, water dwellers, and air dwellers. What

with this classification system?
A. Would all fish be classified into the same
subgroup, even though some live in lakes and
others in oceans?
B. Are penguins classified like other birds, even
though they don't fly?
C. Would two different breeds of dogs be classified
into the same subgroup?
D. How many animals can fit into each subgroup?
