Fungi compete with bacteria for resources
Explanation:
Alexander Fleming discovered the Fungi called Penicillium notatum. He discovered that his culture was contaminated by a Fungi mold and the Bacteria in the culture were dying.
He figured out the mold as the cause and found it to be Penicillium. He also discovered the death was caused by the competition of fungi and bacteria for available resources and the fungi’s interference with the cell wall(cell lysis) of the bacteria.Several years later after technological advancements and researches , the fungi was extracted and isolated and produced in large quantities as a potent antibiotic.

Explanation:
A mold or cast fossil is the shape of the animal's body that displaced dirt and sand. Meanwhile, a true form fossil would only show the animal's appearances. Trace fossils are fossils such as footprints that help identify an animal's behavior.
