How are animals and plants involved in physical and chemical weathering?

Many living organisms are involved in the weathering process. This is especially true for microscopic organisms and plants, although some animals also take part. For example, lichens (made up of fungi and algae) attach themselves to stones and decompose their surface. The root system of plants breaks up the breed, penetrating into it. Fungi can grow in the pores of rocks and dissolve them. And animals participate in this process when they dig nests and tunnels (like moles, worms, etc.), trample the soil, etc.
