Microorganisms are tiny living things that cannot be seen with the naked eye. Some microorganisms are useful, like those that help make bread rise, while others are harmful and can cause illness. Animals and plants have various survival strategies to ensure their species continue, such as caring for offspring or having mechanisms to disperse seeds. Food chains show the feeding relationships between organisms in an ecosystem, and food webs illustrate the complex interactions between multiple food chains.

- 7. 3.1 Food Chain Animalsand the food they eat Classify animals into herbivore, carnivore and omnivore. Producer ConsumerConstruct food chain Green plant obtain energy from the sun to make food. Green Plant as a producer Herbivore : Animals that eat plants only. e.g.: cow, goat, deer Carnivore: Animals that eat other animals. e.g.: tiger, lion Omnivore: Animals that eat plants and other animals Animals that eat plant or other animals are called consumers. The food relationship among living things can be shown by a food chain. To construct food chain It must start with plant as a producer. In a food chain the arrow means ‘eaten by’ All living things need food to survive. Green plant can make their own food. However animals cannot make their own make their own food.
