c ompound leaf - a leaf with more than one blade. All blades
are attached to a single leafstem. Where the leafstem attaches to
the twig, there is a bud. C onifer - A cone-bearing tree. D
eciduous - Shedding all leaves annually.

The outer bark is the tree's protection from the outside world.
Continually renewed from within, it helps keep out moisture in the
rain, and prevents the tree from losing moisture when the air is
dry. It insulates against cold and heat and wards off insect
enemies. The inner bark, or phloem, is pipeline through which food
is passed to the rest of the tree. It lives for only a short time,
then dies and turns to cork to become part of the protective outer
bark.

It is important to remember that proper tree care starts when
you select a tree and that what you do to your tree in its first
few years of life will affect its shape, strength, and even its
life span. Following these steps will make sure tree gets on the
correct foot and keep it healthy throughout its life. 1.Find a Tree

in winter, new leaves are red-tinged, turning to green. Fall color
is deep red or yellow. Flowers are also red. Fast growing and
tolerant of many soils. Grows to 40' to 60', 40' spread. (zones 3-

Blue whales are the largest animals ever known to have lived on
Earth. These magnificent marine mammals rule the oceans at up to
100 feet (30 meters) long and upwards of 200 tons (181 metric
tons). Their tongues alone can weigh as much as an elephant. Their
hearts, as much as an automobile. Blue whales reach these
mind-boggling dimensions on a diet composed nearly exclusively of
tiny shrimplike animals called krill. During certain times of the
year, a single adult blue whale consumes about 4 tons (3.6 metric
tons) of krill a day.
Slide 17
Blue whales are baleen whales, which means they have fringed
plates of fingernail-like material, called baleen, attached to
their upper jaws. The giant animals feed by first gulping an
enormous mouthful of water, expanding the pleated skin on their
throat and belly to take it in. Then the whale's massive tongue
forces the water out through the thin, overlapping baleen plates.
Thousands of krill are left behindand then swallowed.

The blue whale is the largest animal known to have ever lived
on Earth and is the largest mammal in the world. These massive
creatures are hefty from the moment they are born and continue to
add to their girth throughout their first year. A blue whale calf
weighs two tons (1,814 kilograms) at birth and gains an extra 200
pounds (91 kilograms) each day of its first year. Blue whales are
able to breathe air, but they are very comfortable in the ocean
waters where buoyancy helps to support their incredible bulk. These
mammals are found in all the world's oceans and often swim in small
groups or alone. They usually spend summers feeding in the polar
regions.
