ANIMALS





Animals are living things. Living things are born, grow, reproduce and die. Living things have three life processes: nutrition, interaction and reproduction.


Animals are classified into vertebrates and invertebrates.


Vertebrates have a backbone. Mammals, birds, reptiles, amphibians and fish are vertebrates.   









Invertebrates don´t have a backbone. Insects, spiders and molluscs are invertebrates.
