LIVING THINGS

BIOLOGY • Is the study of living things or organisms • How do we identify living from non-living?

7 CHARACTERISTICS OF LIVING THINGS • • Movement Respiration Sensitivity Nutrition/Feeding Excretion Reproduction Growth MRS. NERG

MRS. NERG M = MOVEMENT Animals and plants are able to move. Can you give examples of movement for animals and plants? R = RESPIRATION Animals and plants need energy to carry out the functions that keep them alive. Where do they get this energy? S = SENSITIVITY Living things notice and react to changes in their surroundings. These changes are called stimuli. Can you give examples of stimuli?

N = NUTRITION Living things need to take in food for energy Can you suggest how animals and plants get nutrition? E = EXCRETION Living things have to get rid of unwanted waste products. R = REPRODUCTION Living things produce offspring. G = GROWTH Living things grow and increase in size

LIVING or NON-LIVING?

CLASSIFICATION • Is the sorting of organisms into groups according to similarities between them • Organisms are divided into two main kingdoms: Animal kingdom Plant kingdom

ANIMAL KINGDOM • Divided into 2 main groups Vertebrates- Have a backbone Invertebrates- Have NO Backbone

Vertebrates Invertebrates Fish Worms Amphibians Insects Birds Spiders Reptiles Crabs Mammals Jellyfish Snail

FISH • Live in Water • Have Scales • Breathe using Gills • Have Cartilage or Bony skeleton • Cold Blooded • Examples: Salmon, Cod, Sharks, Plaice

AMPHIBIANS • Moist skin • Live in water OR land • Cold blooded • Examples: Frogs, Toads, Newts

BIRDS • Have feathers • Toothless beaks • Breathe with lungs • Examples: Pigeon, Sparrow, Ostrich

REPTILES • Dry scaly skin • Lay eggs on land • Examples: Crocodiles, Lizards, Snakes and Turtles

MAMMALS • Have body hair or fur • Warm Blooded • Mothers produce milk to feed their young • Examples: Dogs, Bats, Whales, Humans

PLANTS • Plants are also living organisms • Cannot move like animals do • Contain a green chemical called Chlorophyll • Make their own food by a process called Photosynthesis • Identified by their shape, leaves and flowers

A KEY • A key is a set of simple questions used to identify an animal or plant
