What do phylum oomycota mainly feed on?

Phylum Oomycota, commonly known as water molds, primarily feed on decaying organic matter and can also be pathogens of plants and animals. They absorb nutrients through their cell walls by secreting enzymes that break down complex organic materials. Some species are known to cause diseases in crops, such as late blight in potatoes. Overall, they play a crucial role in nutrient cycling in aquatic and terrestrial ecosystems.
