Question

Identify the relationships given in the scenarios below. Choose from: Mutualism, Commensalism, Parasitism, Competition 1. The saguaro cactus is a very large species of cactus that lives in the Sonora Desert of Arizona. Its white flowers are pollenated at night by the Mexican long-tongued bat. The bat licks the nectar from the flowers, getting nourishment. It also spread pollen as it moves from one plant to the next. 2. Certain species of orchids can grow on trees. The orchid is called an epiphyte (plant growing on another plant). When growing on the tree, the orchid gets better access to sunlight and moisture. However, the orchid has specialized roots which can absorb moisture from and nutrients from humid air without taking these away from the host plan. 3. Cattle in Florida are often seen with a white bird sitting on their backs. The bird is a cattle egret and it eats the ticks which are common in grazing herbivores. 4. Black walnut trees store toxic compounds in their leaves, buds, roots and the hulls of the nuts. The compound is called juglone and this builds up in the soil about the tree. This compound will inhibit the growth of pine trees, tomatoes, potatoes and a number of other plants. 5. A lichen is an association between a certain species of fungus and a certain species of algae. The fungus absorbs water and minerals; the algae provide food through photosynthesis.
