A. Herbivores feeding on plants is an example of predation, as they consume the plant material for sustenance.
B. Mycorrhiza is a mutualistic association between fungi and plant roots, where the fungi provide nutrients to the plants
While benefiting from the carbohydrates produced by the plants.
C. Sheep and cattle (herbivores) competing for limited food can be considered an example of competition.
D. Orchids growing on trees without causing harm or benefiting the tree is an example of commensalism, where
one organism benefits (orchid) while the other is unaffected (tree).
