Biodiversity is the range of different living species that live in a place.

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

Extinction is the permanent loss of a species.

Conservation is the process of protecting biodiversity and the environment.

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.

Biodiversity

The number of different organisms in a habitat.

True or False? Adaptations are physical features

Match the plant adaptation to its benefit for the plants survival.

 Leaves growing towards the light and roots growing downwards towards water are examples of {{}} adaptations.

Which of the following are the main human causes of biodiversity loss?

Which of the following could increase biodiversity?

It is the range of different living species that live in a place.

It's made up of all the living organisms in a place, interacting with each other

It's the place where an organism lives. It must provide food, water and shelter.

All the non-living things in an environment.

{{}} is the process of protecting biodiversity and the environment.

A high biodiversity helps to keep ecosystems healthy.

Humans need to grow large fields of single crops such as wheat to survive.

Organisms interact and rely on each other to meet their needs and survive.

Humans rely on lots of different species for food and medicines.
