1 © OUP: To be used solely in purchaser’s school or college Habitats Adaptation Feeding relationships 7C Environment and feeding relationships

2 © OUP: To be used solely in purchaser’s school or college Habitats 7C Environment and feeding relationships

3 © OUP: To be used solely in purchaser’s school or college 7C Habitats – A place to live The place where an organism lives is called its habitat. It feeds for sixteen hours a day, eating about 180 kilograms of leaves and grasses and drinking 230 litres of water! The Asian elephant is an endangered species that lives in forested areas.

4 © OUP: To be used solely in purchaser’s school or college 7C Habitats – A place to live What should this new habitat provide for these endangered animals? A habitat provides all the basic requirements for survival. A wildlife park is planning a new enclosure for a herd of Asian elephants.

5 © OUP: To be used solely in purchaser’s school or college 7C Habitats – Basic requirements food Match each requirement with the correct description. … needed for protection from predators and extreme weather … needed for energy and growth … needed for growth and for reproduction to ensure survival of each species … needed for growth, digestion, getting rid of waste and transporting valuable substances within the organism spaceshelterwater Every habitat should provide… food space shelter water

6 © OUP: To be used solely in purchaser’s school or college Can the garden be described as the squirrel’s habitat? 7C Habitats – Basic requirements A population of squirrels live in a wood and are also found in gardens adjacent to the wood.

7 © OUP: To be used solely in purchaser’s school or college 7C Habitats – Different types of habitat

8 © OUP: To be used solely in purchaser’s school or college Name 3 other habitats and an organism that lives in each. 7C Habitats – Different types of habitat Animals and plants are found in many different types of habitat.

9 © OUP: To be used solely in purchaser’s school or college 7C Habitats – Differences between habitats All habitats provide the same basic needs but there are very different environments across the world.

10 © OUP: To be used solely in purchaser’s school or college Adaptation 7C Environment and feeding relationships

11 © OUP: To be used solely in purchaser’s school or college 7C Adaptation – What is an adaptation? Why are there no sharks in the desert? ! Why are there no cacti in Antarctica? ! Why are there no penguins in the rainforest? !

12 © OUP: To be used solely in purchaser’s school or college An adaptation means the organism can cope with the conditions in its environment and get all it needs to survive. Organisms are able to survive in different habitats because they are adapted to live there. How are sharks, cacti and penguins adapted for survival in their particular habitats? 7C Adaptation – What is an adaptation?

13 © OUP: To be used solely in purchaser’s school or college 7C Adaptation – Feeding adaptations Organisms are adapted to getting food from their habitat.

14 © OUP: To be used solely in purchaser’s school or college 7C Adaptation – Feeding adaptations Match the organism to its correct description. mousefalconpigfish-eating eaglefox mouse falcon pig fish-eating eagle fox This organism has large incisors (front teeth) which enable it to gnaw through hard shells. This organism has a good sense of smell so it can smell roots and other food under the soil. This organism has sharp claws and scaly feet to enable it to grip slippery prey. This organism can fly at speeds up to 30m/s as it catches prey like pigeons. This organism has very good eyesight which enables it to hunt for prey.

15 © OUP: To be used solely in purchaser’s school or college How do the conditions in habitats vary during a 24-hour period? 7C Adaptation – Daily changes

16 © OUP: To be used solely in purchaser’s school or college How do habitats vary at different times of the year? During the different seasons there may be changes in… temperature light intensity vegetation rainfall Why do organisms have to adapt to seasonal changes? 7C Adaptation – Seasonal changes

17 © OUP: To be used solely in purchaser’s school or college Which season does each of these adaptation take place in? AdaptationSeason Arctic fox grows a thick, white furry coat bees collect nectar to make honey horse chestnut tree loses its leaves buds start to open and blossom swallows migrate South Arctic foxes moult changing from white to brown hedgehogs hibernate in their burrows wasps build their nests 7C Adaptation – Seasonal changes

18 © OUP: To be used solely in purchaser’s school or college 7C Adaptation – What’s my adaptation? All animals are adapted to the habitat in which they live.

19 © OUP: To be used solely in purchaser’s school or college 7C Adaptation – What’s my adaptation? All animals are adapted to the habitat in which they live.

20 © OUP: To be used solely in purchaser’s school or college Feeding relationships 7C Environment and feeding relationships

21 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships - Who eats what? If one living thing is eaten by another living thing they have a feeding relationship. These words are used to describe feeding relationships... producer consumer herbivore carnivore omnivore Match each word to the correct definition. … an animal that only eats animals. … produces its own food using the Sun's energy. … an animal that only eats plants. … cannot produce its own food and eats other organisms to survive. …an animal that eats both plants and animals. producer consumer herbivore carnivore omnivore

22 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships - Predator or prey? sharp teeth for tearing easily startled eyes on the side eyes forward acute vision and sense of smell camouflaged claws for piercing and gripping horns to protect them acute hearing and sense of smell may ambush or hunt by stealth Decide if each adaptation is a characteristic of a predator or prey. sharp teeth for tearing easily startled eyes on the sideeyes forward acute vision and sense of smell camouflaged claws for piercing and gripping horns to protect them acute hearing and sense of smell may ambush or hunt by stealth predatorprey

23 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships – Food chain = energy chain A food chain shows how organisms are connected by what they eat.

24 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships – Create a food chain In this food chain which organism is the top carnivore, the herbivore, the primary consumer and the producer?

25 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships – Connecting food chains Most organisms are part of more than one food chain. Connected food chains form a network called a food web.

26 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships – Woodland food web A food web shows how plants and animals in a habitat depend on each other. Identify the carnivores, herbivores and producers on this woodland food web. How many food chains are there in this food web? How is a food web more useful than a food chain?

27 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships – Feeding quiz 2. What are herbivores also called? a)Primary producers. b)Primary consumers. c)Primary schools. 1.Animals that are hunted by predators are called… a)grey. b)prey. c)spray.

28 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships – Feeding quiz 4. Which of these statements is not true of a food chain? a)It shows how an organism uses energy. b)It shows energy is passed from one organism to another. c)It shows feeding relationships between organisms. 3.What is the energy source for all life on Earth? a)The rain. b)The soil. c)The Sun.

29 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships – Feeding quiz 5.What does the arrow in a food chain or food web show? a)The direction of electricity flow. b)The direction of water flow. c)The direction of energy flow. 6. Look at this African-grassland food chain: Which organism is the producer? a)Acacia tree. b)giraffe. c)lion. Acacia tree giraffe lion

30 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships – Feeding quiz 7.Look at this woodland food chain: Which organisms are carnivores? a)Lettuce and snail. b)Snail and blackbird. c)Blackbird and owl. lettuce snail blackbird owl

31 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships – Feeding quiz 8. Read these statements about a marine habitat. Angelfish feed on sea urchins. Sea urchins feed on sea lettuces. Sharks feed on angelfish Which of these is the correct food chain? angelfish sea urchin sea lettuce shark sea lettuce sea urchin angelfish shark angelfish sea urchin sea lettuce b) a) c)

32 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships – Feeding quiz 9.Use this information to complete the seashore food chain: Seaweed is eaten by limpets, starfish are eaten by seagulls and limpets are eaten by starfish. limpet

33 © OUP: To be used solely in purchaser’s school or college 7C Feeding relationships – Feeding quiz 10. Use this information to complete the grassland food web: Zebras are eaten by hyenas and lions. Zebras and baboons feed on grasses. Lions also feed on hyenas and baboons. zebra
