1Where do Minibeasts fit? Are little things in life as important as big things?Are caterpillars as important as eagles?Are snails as important as chickens?Are mosquitos as important as swans?
2Animals and plants in a habitat are involved in a feeding relationship Predators kill other animals for food. The animals that are eaten are usually called prey.Talk with your group about two examples of prey that a bird might eat?To understand why minibeasts are important we need to have some understanding of their role in food chains and more accurately in food webs.Common terms that students will need to know arefeeding relationships-the relationships between animals and plants in a habitatHabitat-the envrionment which provides
6A food chain shows us the relationship between animals and plants ProducersPlants are called producers because they produce their own food. They get their energy from the sun.Primary ConsumerAnimals that get their energy (food) from green plants are called herbivoresSecondary ConsumersAnimals that eat herbivores are called carnivoresTertiary ConsumersAnimals that eat secondary consumersTop ConsumerAnimals at the top of the food chain
7Suggestions:Have this slide in editable view so that students can arrange the animals with either a mouse or on an interactive whiteboard.Print out this slide and have students rearrange them.Talk with the others in your group about how you would arrange these plants and animals into a food chain.
8But food chains are actually much more complicated than this Can you explain this one?

Suggestions for discussion might be around what role the snail and cricket play in this web and the consequences of their removal.Secondary producerPrimary ProducerPrimary ProducerProducer
