2. • A diverse group of organisms that
share certain characteristics
• Some members of this kingdom seem
like they would fit in elsewhere
• Largest of all kingdoms and the major
group of animals are classified under
this kingdom
3. ANIMAL SPECIES
• Somewhere around 9-10 million
species of animals inhabits the earth
• About 800,000 species are identified.
4. ANIMAL
REPRODUCTION
• Most animals reproduce sexually, by
means of differentiated haploid cells(eggs
and sperm)
• Mosy animals are diploid,meaning that the
cells of adults contain two copies of the
genetic material.
5. CHARACTERISTICS
• They are heterotrophic and multicellular
• They all vary in size
• Compose of 9 phyla
• 2 classifications
—Invertebrates:without backbone
—Vertebrates:with backbone
6. PHYLUM
PORIFERA• Also known as SPONGES
• Have PORES or HOLES in their bodies and a
single large opening called OSCULUM
• Filter feeders
• Has two layers of cell
Epidermal cell
Collar cell
7.
8. PHYLum cnidaria
• Hollow,tube-like bodies
• Presence of nematocyst
• Bodies are conmposed of two layers of
tissue:epidermis and gastrodermis
• Food is ingested and expelled through the
gastrovascular cavity
9. Phylum platyhelminthes
• Commonly known as flatworms
• Flat bodies
• They posses only a hollow sac
with single opening for food and
waste excretion
13. Phylum annelida
• Characterized by ring like body
parts
• Have similar segments throughout
their bodies
• Presence of mouth and anus
• Have hearts and blood vessels
14. Phylum mollusca
• Have softt bodies
but they have hard
protective shells as
outer body
covering
• Mussels,clams,and
oyster are
examples
15. Phylum arthropoda
• Most diverse of all the phyla
• Exhibiths CEPHALIZATION
• Well developed nervous system(brain,and nerve cord
• Have segmented bodies
• Body is divided into 3 segments (head,thorax and
abdomen)
• Exoskeleton is made up of chitin
16. Phylum echinodermata
• Has a tube feet of canals
• For sucking in seawater to
obtainnutrients and for expelling
wastes.
17. Phylum chordata
• Three distinguishing structures:
—Notochord
—Skull
—Vertebral column or backbone
19. Ecological Importance
• Every life form an important role in the ecological
balance of the earth. For example, carnivores are
a natural way of controlling population of
herbivores in forests and grasslands. If there were
no carnivores, then the population of these
herbivores would grow so much they could clear
considerable area of forests and grasslands in
their bid to feed themselves
20. Economic Importance
• The silkworm belongs to the phylum arthropoda of
the animal kingdom. Silk from silkworm (and also
artificial fibers in some cases) support the silk
industry which has an annual commercial value of
$200-$500 million. The dairy industry, wool industry,
leather and tanning industry and the fishing industry
are some sectors that not only provide employment
to millions but also fulfill a number of needs of
human beings.
21. Nutritional Importance
• Meat is an important source of proteins,
which are the building blocks of our
body.Milk from cow is an important
source of proteins, carbohydrates, fats,
vitamins and minerals like calcium,
potassium, potassium and magnesium.
22. Pollinators and Food
Crops
• According to a news published by the University of
California, Berkeley, bees, bats and birds are
important pollinators that are responsible for the
pollination of around 35 percent of crops that feed
the entire human population. Without these
pollinators, the human race would run into an
acute food shortage.

Lahat ng may buhay sa mundo ay importante. Like carnivores and herbivores kung walang carnivores then yung population
