A species of malaria-carrying mosquito lives in a forest in which two species of monkeys, A and B, coexist. Species A is immune to malaria, but species B is not. The malaria-carrying mosquito is the chief food for a particular kind of bird in the forest.

Textbook Question

Truffles (the fungi, not the chocolates) are the reproductive bodies of ascomycetes that form mycorrhizae with certain tree species. They are highly prized by gourmets for the delicious scent they add to food. Because truffles grow underground, they are difficult to find—human noses are not sensitive enough to locate them. Many animals, however, are excellent truffle hunters and eagerly consume the fungi. Why would these fungi produce a scent that attracts fungus-eating animals?

Textbook Question

SCIENTIFIC THINKING As you learned in symbiotic relationships with mycorrhizal fungi are found in almost all present-day plant lineages. Mosses are a major exception—most mosses lack mycorrhizal associations. Assuming that mycorrhizae were a key factor in the colonization of land by plants, propose an explanation for the absence of mycorrhizae in present-day moss lineages.

Textbook Question

The carnivorous plant Nepenthes bicalcarata ('fanged pitcher plant') has a unique relationship with a species of ant—Camponotus schmitzi ('diving ant'). The diving ants are not digested by the pitcher plants, but instead live on the plants and consume nectar. Diving ants also dive into the digestive juices in the pitcher, swim to the bottom, and capture and consume trapped insects, leaving uneaten body parts and ant feces behind. What nutritional impact do the ants have on fanged pitcher plants? Do the pitcher plants derive any nutritional benefit from this relationship?
