Global challenges

Ecologists study the distribution of living organisms in habitats to find out how healthy it is. They use many different sampling methods to provide quantitative data which is then analysed.

Biodiversity is a measure of how many different species live in an ecosystem. Human activities like changing land use, deforestation and peat bog destruction reduce this.

This interactive quiz is suitable for GCSE Biology (single science) students studying biodiversity and the impact human activity has on it.

Factors such as the increase in population, new pathogens and overhunting can result in food scarcity. Improved farming techniques, sustainable fisheries and biotechnology can help increase supply.

This interactive quiz is suitable for GCSE Biology (single science) students studying food production and how various factors affect productivity.

Health is the state of physical and mental well-being. Factors can work together to both physical and mental health. A disease is a disorder that affects an organism’s body, organs, tissues or cells.

This interactive quiz is suitable for GCSE Biology (single science) students studying communicable diseases, including the viruses, bacteria and protists that can cause them.

Pathogens are everywhere. The body has evolved defences that act to prevent pathogens entering it. If a pathogen does enter the body then the immune system helps to fight it off.

This interactive quiz is suitable for GCSE Biology (single science) students studying communicable diseases and how the body and medicine work to prevent them.

This interactive quiz is suitable for GCSE Biology (single science) students studying treating and preventing diseases - through the provision of vaccinations and antibiotics.

Monoclonal antibodies are identical copies of one type of antibody. They are incredibly useful in medicine for diagnosis and treatment of diseases.

This interactive quiz is suitable for GCSE Biology (single science) students studying bacterial growth and how medicines have been developed to fight illness.

Pathogens are disease-causing viruses, bacteria, fungi or protists, which attack plants as well as animals. Plants have physical and chemical defences against pathogens.

This interactive quiz is suitable for GCSE Biology (single science) students studying the physical and chemical defences plants have to combat diseases.

The chance of developing a non-communicable disease can be increased or decreased depending upon a person’s lifestyle or the genes they inherit. Two common types are cancer & cardiovascular disease.

This interactive quiz is suitable for GCSE Biology (single science) students studying non-communicable diseases such as Type 2 diabetes and tumours.

Scientists find links between diseases and their causes. The information is used to reduce the number of people with the disease by giving lifestyle advice or developing new ways to fight the disease.

This interactive quiz is suitable for GCSE Biology (single science) students studying non-communicable diseases and the role data analysis plays in reporting statistics.

Understanding how to approach exam questions helps to boost exam performance. Question types will include multiple choice, structured, mathematical and practical questions.
