Biodiversity and interdependence
Photosynthesis
Plant and animal cells have similarities and differences and each have important roles to play in the biodiversity of the planet's ecosystem.
Biodiversity and distribution
Sampling helps us to estimate numbers of organisms in an area and build up an accurate picture of that area;s biodiversity.
Food production and fertilisers
When plants are harvested, nutrients are removed from the soil. These can be replaced by natural fertilisers such as manure or by NPK fertilisers containing nitrogen, phosphorous and potassium.
