Some thunderstorms can cause a lot of rain to fall over a short period of time. too much rainfall can affect abiotic resources in the soil
a reducing the nutrients in the soil
b increasing the minerals in the soil
c reducing the oxygen level of the soil
d increasing the temperature of the soil

A reducing the nutrients in the soil

An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.
