ANIMALIA

ANIMALIA

1. Kingdom animalia

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. 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

8. Phylum platyhelminthes Commonly known as flatworms Flat bodies They posses only a hollow sac with single opening for food and waste excretion

9. Phylum nematoda Commonly known as roundworms Round bodies covered with cuticle Ascaris and bookworms are examples

10. Phylum annelida Characterized by ring like body parts Have similar segments throughout their bodies Presence of mouth and anus Have hearts and blood vessels

11. Phylum mollusca Have softt bodies but they have hard protective shells as outer body covering Mussels,clams,and oyster are examples

12. 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

13. Phylum echinodermata Has a tube feet of canals For sucking in seawater to obtainnutrients and for expelling wastes .

14. Phylum chordata Three distinguishing structures: —Notochord —Skull —Vertebral column or backbone

15. Importance of kingdom animalia

16. 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

17. 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.

18. 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. 

19. 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.
