Explain how the increased flammability of chaparral shrubs is a beneficial adaptation.

Trees will compete with shrubs for light and space so by adapting for increased flammability, chaparral scrubs promote natural wildfires to eliminate their competitors. While these fires destroy the trees, the shrubs are still able to germinate afterwards.

As explained below.

Explanation:

Fire plays a crucial role in the development and perpetuation of the chaparral community and the flammability of the chaparral species increases over time through the deposition of the leaf matters and the leat litter. That is impregnated with volatile oils.

It's lithogenous i believe of course i looked it up.
