Explanation:
The watermelon fruit when is covered by the molds, a type of fungus which can grow on the moistened substances. The molds can be characterized by their black, green and white spores.
The molds grow on the moistened surface by growing their hyphae which can form mycelium. These hyphae continuously produce enzymes which can breakdown the organic matter present in the watermelon.
Therefore, the matter and energy of the watermelon are transferred to the molds as it forms the next trophic level in the food chain.
