Master GCSE Biology

MS1

- A community of organisms and their physical environment interacting as a system (1)

MS2

- An organism that feeds on producers (1)

- Example: Rabbit, cow, deer (1)

MS3

- Destruction of habitats, leading to loss of species (1)

- Reduction in ecosystem resilience, making it more vulnerable to environmental changes (1)

- Loss of medicinal plants, potentially impacting human health (1)

MS4

- Producers make their own food from inorganic matter (1)

- Decomposers break down dead organisms into inorganic matter (1)

MS5

- Carbon dioxide is used by producers during photosynthesis (1)

- Released by consumers during respiration (1)

MS6

- Food chain: Linear sequence showing feeding relationships (1)

- Food web: Interconnected food chains that show the flow of energy (1)

MS7

- Availability of resources (e.g., food, water, shelter) (1)

- Climate (e.g., temperature, precipitation) (1)

- Pollution and other environmental stressors (1)

MS8

- Managing forests in a way that ensures their long-term health while meeting human needs (1)

MS9

- High biodiversity provides resilience and adaptability to environmental changes (1)

- Different species can perform similar functions, ensuring ecosystem continuity (1)

- Genetic diversity provides a greater chance of adapting to new conditions (1)

- Loss of biodiversity can disrupt ecosystems and make them more vulnerable to collapse (1)

MS10

- Reduce energy consumption (e.g., using energy-efficient appliances, public transport) (1)

- Reduce waste and recycle (1)
