Master GCSE Biology

MS1

- Biodiversity is the variety of living organisms within a particular habitat, ecosystem, or the planet as a whole. (1)

MS2

- Reduced habitat size can lead to fewer resources and increased competition for food and shelter. (1)

- Animals may have to travel further to find resources, increasing their risk of predation. (1)

MS3

- Producers (e.g., grasses) convert sunlight energy into chemical energy through photosynthesis. (1)

- They are the foundation of the food chain, providing food for consumers. (1)

- Grasslands provide essential habitats for diverse wildlife. (1)

MS4

- A food web is a complex network of interconnected food chains within an ecosystem. (1)

MS5

- Deforestation reduces the number of trees, which absorb carbon dioxide during photosynthesis. (1)

- It increases the release of carbon dioxide into the atmosphere, contributing to climate change. (1)

MS6

- Abiotic factors (e.g., temperature, water availability, pH) influence where organisms can live. (1)

- Organisms are adapted to specific environmental conditions and require suitable abiotic factors to survive. (1)

- Abiotic factors can create different niches within a habitat, supporting specialized communities.(1)

MS7

- One example of a biotic factor is competition between organisms for food or resources. (1)

MS8

- Sustainable farming practices minimize the use of chemicals and promote biodiversity. (1)

- They create wildlife-friendly habitats, reducing the impact on animal populations. (1)

MS9

- Decomposition is the breakdown of dead organisms by decomposers (e.g., bacteria and fungi). (1)

- Decomposers release nutrients back into the soil or water, making them available to producers. (1)

- Decomposition is essential for the maintenance of nutrient cycles and ecosystem stability. (1)

MS10

- One example of a primary consumer is a rabbit. (1)
