Abiotic components are non-living physical and chemical factors of an ecosystem, including soil, water, temperature, light, and minerals.

Soil provides nutrients and a medium for plant growth.

Explanation:
Chlorophyll a is the primary photosynthetic pigment, essential for converting light energy into chemical energy. It directly participates in the light reactions. Chlorophyll b, carotenes, and xanthophylls are accessory pigments that capture additional wavelengths and transfer energy to chlorophyll a. These accessory pigments also protect chlorophyll from photo-oxidation.
