AQA GCSE Science – Combined science foundation Ecology GCSE Biology – Biotic and abiotic factors

Learning Objectives

-I can describe what an organism needs to survive and reproduce
-I can describe what different organisms compete for
-I can define the term abiotic factor and biotic factor
-I can recall a list of abiotic factors including; light intensity, temperature, water levels, pH, ion content, wind, carbon dioxide and oxygen levels. I can recall a list of biotic factors including; food, predators and pathogens
-I can describe how a change in abiotic and biotic factors could affect a community
