CAIE IGCSE Biology 19.4.4 Factors affecting the rate
Practise explaining how food supply, competition, predation and disease alter population growth using organism data, graphs and real contexts.
How this is tested
- suggest limiting factors behind population changes shown in fish, plant or bacterial data
- explain how food supply, competition, predation or disease changes birth and death rates
