An adaptation is a feature that organisms have to help them live in a particular place.

Extinction is the permanent loss of a species.

Conserving biodiversity

Pupils will learn about biotic and abiotic components of an ecosystem, measuring population size, interdependence and competition in ecosystems, how changes in biotic and abiotic factors affect communities, the cycling of carbon and water, and the role of microorganisms in cycling materials through ecosystems.

Pupils learnt about interdependence in ecosystems, covering food webs and food chains along with predator-prey relationships. The effect of the use of pesticides on organisms such as pollinating insects and top predators through bioaccumulation.

This unit examines environmental changes and their impact on species' survival and adaptation, potentially leading to extinction. It also develops skills for interpreting data and observations, evaluating errors, and using SI units and IUPAC chemical nomenclature in scientific contexts.
