Verified step by step guidance1
Step 1: Understand the concept of biotic and abiotic factors. Biotic factors refer to living components of an ecosystem, such as plants, animals, and microorganisms, while abiotic factors refer to non-living components like sunlight, water, soil, and temperature.
Step 2: Analyze the interaction described in each statement. Determine whether the interaction involves living organisms (biotic factors) or non-living components (abiotic factors).
Step 3: Evaluate the first statement: 'A population of deer grazing on grass in a meadow.' This involves deer (a living organism) interacting with grass (another living organism), which is a biotic interaction.
Step 4: Evaluate the other statements: 'Sunlight warming the surface of a lake,' 'Water evaporating from the soil after rainfall,' and 'Rocks being weathered by wind and rain.' These interactions involve non-living components (abiotic factors) and do not include living organisms interacting with each other.
Step 5: Conclude that the correct statement describing a biotic factor interacting with the environment is 'A population of deer grazing on grass in a meadow,' as it involves living organisms interacting with each other.
