The document discusses how different animal body structures allow animals to adapt to living on land or in water. It provides examples of how scales, shells, gills, and other structures help aquatic animals survive in water, while fur, feathers, lungs, and legs help terrestrial animals live on land. The document also compares body structures that aid in movement, protection, breathing, and survival for various land and water animals.

Motivation

10. Did you know that…..
Animals have body structures that enable them to live in
water and on land. For example, animals can live in water
(aquatic animals) because they have scales, outside skeleton,
shells and gills. Scales are used for protection from diseases
and harmful objects and for swimming. On the adapt on land
terrestrial animals). Adaptation is process of developing for
animals to survive.

12. Facts….
On the other hand, animals have also structures that help
them dapt on land (terrestrial animals). Some animals like dogs,
cats, and monkeys are covered with fur to keep them warm.
Others like birds are covered with feathers for them to have
ability to fly. Some like worms have smooth skin for breathing.
In general, most of animals have body coverings or protection.
They have also parts for movement like legs have lungs for
breathing.

13. Terrestrial Animals

15. About Amphibians
Amphibians are small vertebrates that
need water, or a moist environment, to
survive. ike reptiles, amphibians are cold-
blooded. Because of their special skin they
require very specific living conditions. Too
much sun can damage their cells. Too much
wind can dry their skin and dehydrate the
animal.

38. Loss of habitat is the biggest reason why lots
of animals are becoming extinct. Some
animals are noe endangered because of
deforestation, illegal hunting and selling of
animals. Philippine eagle-owl and Philippine
eagle are endangered specie. In your own
little way , as grade 4 learner what can you do
to help protect the animals?

39. Animals have a different body structure that helps them adapt to
land and water. It serves as their protection or helps them
survived in the environment.
