This document discusses biotic and abiotic factors in ecosystems. It defines biotic factors as living components that directly or indirectly affect organisms, such as plants, animals, fungi and bacteria. Abiotic factors are defined as non-living components that affect living organisms, such as temperature, sunlight, rocks and water. The document emphasizes that biotic and abiotic factors interact with and influence each other within ecosystems.
