Classification & Taxonomy To know what classification is, and to know the main taxonomic groups
Food Chains All food chains require light from the Sun – producers convert this light energy into food via photosynthesis Using the worksheet produce two food chains Stick your completed jigsaws in your book Lettuce Slug Thrush Hawk Producer Herbivore Carnivore 1 Carnivore 2
Classification A cow and a dolphin may look very different but what do they have in common? There are millions (maybe tens of millions) of different species on Earth – some organisms are clearly different, whilst others share many similar features
Common Features
Common Features Many organisms share common features, which allow them to be grouped based on these features – this is classification The classification system begins with very big groups (lots of organisms) and moves down into smaller groups (fewer organisms) The biggest groups are called the kingdoms, of which there are 5
5 Kingdoms What are the 5 kingdoms? living things plants animals fungi monera protoctista Vascular plants Mosses Liverworts Invertebrates Vertebrates Yeast Mushrooms Toadstools Bacteria Blue-green algae Protozoa Filamentous algae

Animals animals vertebrates invertebrates How can different types of animal be classified? animals vertebrates invertebrates Invertebrates are animals that do not have a backbone. They have soft inner bodies which are held in shape by a flexible covering of outer cells or by a hard covering called an exoskeleton. Vertebrates are animals that have a backbone. They have a firm body because of the muscles that connect to their skeleton.
Vertebrates Animal vertebrates are split into 5 classes: - Animal Mammals Birds Reptiles Amphibians Fish
Fish Reptile Mammal Reptile Amphibian Bird Mammal Mammal Mammal Reptile Bird Fish
