A producer is an organism that makes its own food.

A consumer is an organism that eats other organisms for food.

A food chain diagram shows how food is transferred from one population of organisms to another.

A group of organisms of the same type in the same place is called a population.

Scientists use models as simpler representations of complex things and ideas.

Science

Pupils will move on to construct and interpret pyramids of number and biomass from food chains data. Pupils will learn about how plants and animals are adapted to survive and the impact of changes to the environment on biodiversity. The importance of biodiversity and the importance of gene banks. How to sample plant and animal populations to aid our understanding and monitoring of populations. 

In Y4 pupils learnt about their local environment and to recognise that environments can change. Pupils also explored examples of human impact (both positive and negative) on environments. Pupils looked at a variety of food chains to identify producers, predators and prey.
