What is an abiotic factor?

The amount of sunlight available
The interactions between different species
The amount of carbon dioxide in the atmosphere
The behavior of a single organism

The correct answer is: The amount of sunlight available

An abiotic factor is a non-living component of an ecosystem. It refers to physical or chemical factors such as sunlight, temperature, water, and nutrients. Option B is incorrect because it describes biotic factors, which are living things such as different species. Option C is incorrect because it only specifies one abiotic factor (carbon dioxide) and does not encompass all possible abiotic factors. Option D is incorrect because it refers to the behavior of a single organism, which is a biotic factor and not an abiotic one. Option A, the correct answer, is the most comprehensive and accurate description of an abiotic factor.
