GCSE Biology - Abiotic & Biotic Factors (2027/28 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. Understanding Biotic Factors Definition of biotic factors as the living components of an ecosystem that affect other organisms or shape the environment. Examples including predation, competition for resources or habitat, the prevalence of disease, and the availability of food. 2. Understanding Abiotic Factors Definition of abiotic factors as the non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. Examples such as light intensity, temperature, carbon dioxide concentration, moisture levels, wind intensity and direction, and soil pH and mineral content. 3. Impacts and Interactions in Ecosystems How changes in abiotic factors (e.g., temperature) can influence biological processes like photosynthesis and the behaviour or energy expenditure of organisms. Consideration of how organisms are affected by the interplay of various biotic and abiotic factors, including direct and indirect effects. 4. Analysing Factors in a Specific Ecosystem Application of concepts to identify relevant biotic and abiotic factors for a particular organism, using a clownfish and its sea anemone habitat as a case study. ** CHAPTERS ** 0:00 Introduction 0:20 Biotic Factors 1:13 Abiotic Factors 1:50 How Changes in Abiotic Factors Affect Organisms 2:18 Analysing Factors in Ecosystems ** PLAYLISTS **    • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Biology #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
