Verified step by step guidance

1. Begin by understanding the concept of biotic and abiotic factors. Biotic factors are living components in an ecosystem, such as plants, animals, and microorganisms. Abiotic factors are non-living components, like sunlight, temperature, and water availability.
2. Review the options provided: Sunlight, Temperature, Plants, and Water availability. Identify which of these are living organisms.
3. Recognize that plants are living organisms, making them a biotic factor. Sunlight, temperature, and water availability are non-living, thus abiotic factors.
4. Consider the role of plants in a biome. They contribute to the ecosystem by providing oxygen, food, and habitat for other organisms, which are key characteristics of biotic factors.
5. Conclude that among the given options, plants are the correct answer as they are the living component, or biotic factor, in a biome.
