Habitats and foodchains

  1. 1. HABITATS AND FOOD CHAINS
  2. 2. What is a habitat?• A habitat is a place where plants and animals find everything they need to live together – food, water, oxygen, shelter and space .• Different plants and animals live in different habitats.• Some animals belong to several habitats.
  3. 3. What is an environment?• Everything that affects an animal makes up its environment - where it lives, the weather and all the living things it comes into contact with.• Every living thing, including people, has an effect upon the environment.
  4. 4. Animal Adaptation• All living things have to be suited to their environment if they are to survive.• Penguins have wings they use for swimming, not flying. They have two layers of feathers to keep them warm and dry, and they have heavy bones to help them swim.• Stick insects imitate the shape and colour of plants to protect themselves from predators.
  5. 5. How is the seal adapted to its environment? Streamlined shape. Forward-facing eyes for clear vision ahead.Strong teeth tocatch fish. Flippers to help it swim. Thick layer of bodyHind legs have evolved fat to keep it warm.into a a strong rudder-like tail.
  6. 6. Homes and Habitats• The place where an animal lives is called its habitat.• An animal lives where it can find food, water and shelter.
  7. 7. Living things• All living things (organisms) need food (nourishment) to live.• Living things in a habitat depend on each other for food.
  8. 8. Consumers• “Consume” means “eat”.• Animals are consumers because they “eat” (consume) food provided by plants or other animals.
  9. 9. Producers• Plants are living organisms. They need nourishment to survive.• But…• Plants do not eat other plants or animals.• Plants are called producers, because they make their own food.
  10. 10. Predator A predator eats other animals.Cats eat fish So do bears!
  11. 11. Predator• The cat is a predator, because it eats other animals.• The bear is a predator, because it eats other animals.• People are predators too!
  12. 12. Prey• Any animal which is hunted and killed by another animal for food is prey. Predator Prey
  13. 13. Predators and PreySome animals are predators, some are prey - some areboth.The predator eats the prey, and the prey gets eatenby the predator.
  14. 14. Food ChainsA food chain shows what is eaten. The fly is eaten by the bird.
  15. 15. Food ChainsA food chain shows what is eaten. The lettuce is eaten by the rabbit.
  16. 16. Food chains start with a plant. The lettuce is eaten by the slug, the slug is eaten by the bird.
  17. 17. Food Chains - a Reminder• A food chain shows which animals eat other animals or plants.• Plants don’t eat things.• A food chain starts with what gets eaten and the arrows point towards what does the eating.• Food chains only go in one direction.
  18. 18. Where do the arrows point?
  19. 19. The top of the food chain.Some animals are at the top of the food chain.This is because they are not hunted by otheranimals. No other animal hunts the lion. The lion is at the top of the food chain.
  20. 20. Caring for the Environment• It is in our own best interests to look after the world we live in.• If a habitat is lost or damaged, it has an effect on everything else, even if we do not see or understand it straight away.• Remember - once something becomes extinct, it’s gone forever!
