WALT: use food chains and food webs to show the relationships of organisms within an area Tasks: Extract Food Chains Food Web Interdependence Word Game HW: Revise for all work for a test Gwaith Dosbarth Food Chains and Webs I can write my own food chains Success criteria By the end of the lesson: I can link several food chains to make a food web. I can food webs to explain interdependence of species that share a habitat.
2
Extract As your teacher reads out the extract about a habitat. You write down what eats what. Your teacher will write the animal names on the board. HW: Revise all the work for a test Gwaith Dosbarth Food Chains and Webs I can write my own food chains Success criteria By the end of the lesson: I can link several food chains to make a food web. I can food webs to explain interdependence of species that share a habitat. WALT: use food chains and food webs to show the relationships of organisms within an area

A food chain shows where the energy goes in a food chain (in other words, “what gets eaten by what”): Cabbage Rabbit Stoat Fox The arrows indicate where the energy is going Plants convert the sun’s energy into food - Producer Gwaith Dosbarth Food Chains and Webs Eats only plants - Herbivore Eats other animals- Carnivore Animals that eat both animals and plants - Omnivore Primary Consumer Secondary Consumer Top Carnivore/ Consumer WALT: use food chains and food webs to show the relationships of organisms within an area

Food Chains Where does the energy in a food chain originally come from? HW: Revise for all work for a test Gwaith Dosbarth Food Chains and Webs I can write my own food chains Success criteria By the end of the lesson: I can link several food chains to make a food web. I can food webs to explain interdependence of species that share a habitat.
5
Food webs contain many interlinking food chains… Gwaith Dosbarth Food Chains and Webs WALT: use food chains and food webs to show the relationships of organisms within an area
6
Food Web Why are food webs better than food chains? HW: Revise for all work for a test Gwaith Dosbarth Food Chains and Webs I can write my own food chains Success criteria By the end of the lesson: I can link several food chains to make a food web. I can food webs to explain interdependence of species that share a habitat. WALT: use food chains and food webs to show the relationships of organisms within an area
7
Food Web They contain a larger amount of animals and how each one is prey to the other HW: Revise for all work for a test Gwaith Dosbarth Food Chains and Webs I can write my own food chains Success criteria By the end of the lesson: I can link several food chains to make a food web. I can food webs to explain interdependence of species that share a habitat. WALT: use food chains and food webs to show the relationships of organisms within an area
8
Food Web Use the resource sheets to make food chains and then form a food web to represent the living things in the North American desert. HW: Revise for all work for a test Gwaith Dosbarth Food Chains and Webs I can write my own food chains Success criteria By the end of the lesson: I can link several food chains to make a food web. I can food webs to explain interdependence of species that share a habitat. WALT: use food chains and food webs to show the relationships of organisms within an area
9
Interdependence Interdependence – describes relationships in which members of the group are mutually dependent on the others. Have a look at the following food web. What will happen if an animal is taken away? HW: Revise for all work for a test Gwaith Dosbarth Food Chains and Webs I can write my own food chains Success criteria By the end of the lesson: I can link several food chains to make a food web. I can food webs to explain interdependence of species that share a habitat. WALT: use food chains and food webs to show the relationships of organisms within an area
10
Breaking the links e.g take out the crab: 1)What would happen to the population of flat winkles? They would probably ______ because… 2)What would happen to the population of herring gulls? They would probably ______ because … Q. What would happen if an animal or organism was “taken out”? Gwaith Dosbarth Food Chains and Webs WALT: use food chains and food webs to show the relationships of organisms within an area
11
Word Game Your teacher will read the definitions. You write the word being described. HW: Revise for all work for a test Gwaith Dosbarth Food Chains and Webs I can write my own food chains Success criteria By the end of the lesson: I can link several food chains to make a food web. I can food webs to explain interdependence of species that share a habitat.
