Answer

Answer:

a rainstorm

Brief Explanations:

Abiotic factors are non-living components of an ecosystem. A rainstorm is a non-living environmental event, while a prickly pear seed, fallen palo verde leaf, and wolf spider are all living (or once-living, organic) components of the ecosystem, making them biotic factors.
