Part II: MUTUALISM Be able to: Distinguish a mutualistic interaction from other types of species interactions. Distinguish between more facultative and more obligate mutualisms. Distinguish between nutritional and protection mutualisms. Identify the two types of organisms that form a mycorrhizal association. Identify the main commodities that each of these organisms provides to, and receives from, the other. Distinguish between arbuscular mycorrhizal fungi and ectomycorrizal fungi. Predict how the net benefit of mycorrhizal fungi to a plant would vary based on soil fertility.

Unformatted text preview: Identify the group of organisms that provide photosynthate to corals. Identify the main commodities that zooxanthellae and corals each provide to, and receive from, the other. Identify the main commodities that ants and ant-defended plants each provide to, and receive from, the other. Identify the main commodities that corals and crustaceans each provide to, and receive from, the other. Predict how the net benefit of a protective mutualist would depend on the abundance of the predators or herbivores against which it provides protection. Predict generally how the net benefit from an organism to a partner mutualist would depend on environmental conditions. Explain linkages among the above. Reading: Chapter 15. Introduction. Required .
