Questions 10-19Social parasitism involves one species relying on another to (11) raise its young. Among vertebrates, the best known social parasites are such birds as (12) cuckoos and cowbirds; the female lays an egg in a nest belonging to another species and leaves (13) it for the host to rear.(14) The dulotic species of ants, however, are the supreme social parasites. Consider, for example, the unusual behavior of ants belonging to the genus Polyergus. All species of this ant have lost the ability to care for themselves. The workers do not forage for food. feed their brood or queen, or even dean their own nest. To compensate for these deficits, Polyergus has become specialized at obtaining workers from the related genus Formica to do these chores.In a raid, several thousand Polyergus workers will travel up to 500 feet in search of a Formica nest, penetrate it, drive off the queen and tier workers, capture the pupal brood, and transport it back to their nest. The captured brood is then reared by the resident Formica workers until the developing pupae emerge to add to the Formica population, which maintains the mixed-species nest The Formica workers forage for food and give it to colony members of both species. They also remove wastes and (16) excavate new chambers as the population increases.The true extent of the Polyergus ants' dependence on the Formica becomes apparent when the worker population grows too large for the existing nest. Formica scouts locate a new nesting site, return to the mixed-species colony, and (17) recruit additional Formica nest mates. During a period that may last seven days, the Formica workers carry to the new nest all the Polyergus eggs, larvae, and pupae, every Polyergus adult, and even the Polyergus queen.Of the approximately 8,000 species of ants in the world, all 5 species of Polyergus and some 200 species in other genera have evolved some degree of parasitic relationship with other ants.10. Which of the following statements best represents the main idea of the passage? Ants belonging to the genus Formica are incapable of performing certain tasks. The genus Polyergus is quite similar to the genus Formica. Ants belonging to the genus Polyergus have an unusual relationship with ants belonging to the genus Formica. Polyergus ants frequently leave their nests to build new colonies.11. The word raise in the text is closest in meaning to Rear Lift Collect Increase12. The author mentions cuckoos and cowbirds in the text because they Share their nests with each other Are closely related species Raise the young of other birds Are social parasites13. The word it in the text refers to Species Nest Egg Female14. What does the author mean by stating that The dulotic species of lifts... are die supreme social parasites (in the text) ? The Polyergus are more highly developed than die Formica. The Formica have developed specialized roles. The Polyergus are heavily dependent on the Formica. The Formica do not reproduce rapidly enough to care for themselves15. Which of the following is a task that an ant of the genus Polyergus might do? Look for food. Raid another nest Care for the young. Clean its own nest.16. The word excavate in the text is closest in meaning to Find Clean Repair Dig17. The word recruit in the text is closest in meaning Create Enlist Endure Capture18. What happens when a mixed colony of Polyergus and Formica ants becomes too large? The Polyergus workers enlarge the existing nest. The captured Formica workers return to their original nest. The Polyergus and the Formica build separate nests. The Polyergus and the Formica move to a new nest.19. According to the information in the passage, all of the following terms refer to ants belonging to the genus Formica EXCEPT the Dulotic species of ants (paragraph 2) Captured brood (paragraph 3) Developing pupae (paragraph 3) Worker population (paragraph 4)
