Which of the following best explains this difference? a) Fungi, like mushrooms, do not rely on photosynthesis and hence do not need to attract or warn herbivores with bright colors. Plants have a symbiotic relationship with herbivores, which is not the case for mushrooms. Mushrooms are typically more toxic than plants, so there is no need for them to develop warning colors. Most of a fungus's body is the mycelium which exists underground, hence consumption of the above-ground mushroom cap represents a comparatively smaller fitness cost than for plants, whose vital photosynthetic structures can be consumed by herbivores.arrow_forward6.)

Loss of habitat 8.) Cocolisap infestation outbreak has been declared in some parts of the Philippines. The cocolisap feeds on the sap of the coconut tree and injects toxic enzymes, resulting in discolored leaves and deformed plant tissues that retard its growth of coconut tree. This, results in a decrease of the survival rate of coconut trees. Which of the following factors limits the population of coconut trees? a.) Diseases and parasites b.) Competition for resources c.)
