A producer is an organism that makes its own food.

Grains of pollen carry genetic material between flowers to enable flowering plants to reproduce.

Pollination is the process where pollen is transferred to the female organs of a plant, to enable seeds to be made.

Organisms are interdependent when they rely upon each other for their survival.

Food security is having enough food to feed the human population.

Food chains

Predator-prey relationships

Adaptations of predators and prey

Food webs

Ecosystems and habitats

Using chemicals in farming

Bioaccumulation

The importance of biodiversity

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.

This unit explores the interdependence of organisms in ecosystems, including food webs and insect-pollinated crops. It examines how organisms interact with their environment and the impact of toxic materials. It also highlights the importance of biodiversity and preserving genetic material.
