Abiotic factors refer to non-living environmental conditions such as sunlight, temperature, rainfall, and soil composition. Biotic factors refer to living organisms such as plants, animals, and other organisms that inhabit an environment. Examples of biotic factors include grass providing energy for cows and abiotic factors including sunlight affecting whether plants can grow. The document discusses the difference between abiotic and biotic factors and provides homework questions about examples of each, definitions of populations and communities, and whether certain atmospheric gases are abiotic factors.

1. Abiotic and Biotic Factors8 Science

2. What is the difference?Abiotic and biotic factors are features of the environment Biotic factors:‘bio’ = livingLiving or once-living organismsExample: grass is a living thing and is part of the school environment, gives cows in the fields energy

3. What is the difference?Abiotic factors:‘a’ = notabiotic = non-living thingsThese factors help determine whether a species can survive in an areaExample: sunlight affects whether a plant can grow

4. ABIOTIC or BIOTIC?

5. HOMEWORK QUESTIONS: do not need to copy the question, just the answers in FULL SENTENCESWhat is the difference between an abiotic and a biotic factor? Give at least 5 examples of each (that we have NOT already used today)What is the difference between a population and a community?
