2. About grasslands animals
Grasslands lack the trees and heavy
bush to hide many creatures. Because
of the open landscape and the widely
spaced trees, grasslands are home to
large herds of grazing mammals such
as the zebra and bison. Annual rainfall
in the grasslands is between 10 to 30
inches, there is a seasonal drought
every year. Many animals are active
only during the rainy season
4. About aquatic habitats
When considering aquatic habitats,
many variables come to mind.
Obviously, there is a continuum of
salinity ranging from essentially distilled
water at glacier faces and high mountain
streams, to other freshwaters, to
estuaries where fresh and salt waters
mix, to oceans, to hypersaline
environments such as the Great Salt
Lake. Current is another factor; water
may be still and stagnant, or flow in
currents of various velocities.
5. What is aquatic habitat ?
Healthy and diverse habitats mean healthy and diverse
populations of fish. Habitats are simply those places
where aquatic species live.
Aquatic habitats can be described in many ways including:
the natural materials that comprise the habitat (e.g. rocks,
coral, gravel, sand and mud),
the type of vegetation present (e.g. macrophytes, snags,
seaweeds, seagrasses, mangroves and saltmarsh),
the shape and nature of the habitat (e.g. pools and riffles,
billabongs, reefs), or
the overall ecosystem (e.g. wetlands, floodplains,
streams, estuaries, lakes, beaches).
6. How fish use aquatic habitats ?
We all know fish live in water. However, water alone will
not ensure that a fish is able to survive. Fish need habitat!
The habitat is the water and all the other things that the
fish needs to complete its lifecycle: like food and places to
shelter (like snags or coral) and to breed (like gravel beds
or seagrass). Some native fish also have to move between
different habitats as they mature and breed.
Different species have different habitat requirements and
these may change throughout a fish’s life.
A fish’s habitat is more than just the water. The water has
to be the right type (freshwater, estuarine or saltwater),
temperature, quantity (depth and flow) and quality.
8. About mountain region animals
These habitats are normally very cold
and windy . In some areas , snowfall may
take place in winters there is a large
variety of plants and animals living in the
mountain regions. Animals living in the
mountain regions are also adapted to the
conditions there . They have thick skin or
fur to protect them from cold. For
example :- yaks have long hair to keep
them warm. Snow leopard has thick fur
on its body including feet and toes.
9. This protect its feet from cold when it walks
on the snow. The mountain goat has strong
hooves for running up the rocky slopes of the
mountains.
11. About desert
Animals in the desert must survive in a
hostile environment. Intense heat, searing
sun, and lack of water are just a few of the
challenges facing desert animals. Animals
that live in the hot desert have many
adaptations. Some animals never drink, but
get their water from seeds (some can contain
up to 50% water) and plants. Many animals
are nocturnal, sleeping during the hot day
and only coming out at night to eat and hunt.
Some animals rarely spend any time above
ground. Spadefoot toads spend nine months
of every year underground!
12. A desert is defined as a region that
receives very little rainfall. It can be
hot or cold. These are various types of
deserts all around the world, from the
harsh elements of sahara desert in
africa to the four desert of the south
western united states . Areas in
antarctica are examples of cold
deserts.
13. The animals that live in the desert usually
have special adaptations that allow them to
survive the extreme temperatures and
conditions that are present in a desert. A
good example of an animal with special
adaptations is the camel. A camel can drink
very large amounts of water in one day or
survive for a relatively long time without
drinking any water.
Some animals of the desert are also
endangered, including the Lappet-Faced
Vulture, which is categorized as vulnerable.
