  • Note: Green plants can be subdivided into those with vascular tissues (xylem and phloem) and complex leaves with a waterproof cuticle, and those without .
  • This slide is the names of eight different organisms. Drag their name into the correct table depending on whether you think that they are a producer or a consumer.

    10. 10. Surviving in a habitat Organisms need to have special features which help them to survive in their habitat. These special features are called adaptations. For example, you have plenty of adaptations to survive in your habitat. Your fingers are an excellent adaptation. Without their ability to grip you would not be able to do all of that schoolwork! Some adaptations are obvious while others are not so obvious. Can you think of any other adaptations that you have?1 of 2010 of 25 © Boardworks Ltd 2004 2005

    13. 13. Feeding types Animals can be grouped in several ways. One way of doing this is based on how animals feed. Some organisms are producers. Producers make their own food. Plants produce their own food using light energy from the Sun. Some types of bacteria can also make their own food by using light or chemical reactions. Consumers cannot make their own food. They must consume other organisms to get the food that they need.1 of 2013 of 25 © Boardworks Ltd 2004 2005
    14. 14. Producer or consumer?1 of 2014 of 25 © Boardworks Ltd 2004 2005
    15. 15. Consumers Consumers can be grouped into different types: Herbivores These consumers eat producers. This means plants and possibly bacteria. Carnivores These consumers eat other consumers. They eat animals. Omnivores These consumers eat other consumers and producers. They eat animals and plants. Most humans are omnivores.1 of 2015 of 25 © Boardworks Ltd 2004 2005

    17. 17. Changes in food chain populations The organisms in a food chain are dependent on each other. Changes in the number of organisms in one part of the food chain can have dramatic effects on the rest of the food chain. grass rabbit fox What would happen to the number of rabbits and foxes if all the grass died out? Rabbit numbers would decrease because they would have less to eat and may starve or stop reproducing. Fox numbers would also fall as there would not be as many rabbits to eat.1 of 2017 of 25 © Boardworks Ltd 2004 2005
    18. 18. Food chain populations plankton shrimp tuna dolphin 1. It has been a very bad year for plankton. Due to the lack of food their numbers have dropped dramatically. Use the sliders to show how this will affect the numbers of the other members of the food chain.

    19. 19. Food chain populations plankton shrimp tuna dolphin 2. Dolphins are often killed by being caught in the driftnets of fisherman. More dolphins than ever have been killed in this particular year and so the number of dolphins is very low. Use the sliders to show how this will affect the numbers of the other members of the food chain.
