A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This gut flora is made up of cellulose-digesting protozoans or bacteria living in the herbivores' intestines. Coral reefs are the result of mutualisms between coral organisms and various types of algae that live inside them. Most land plants and land ecosystems rely on mutualisms between the plants, which fix carbon from the air, and mycorrhyzal fungi, which help in extracting water and minerals from the ground.

What type of fungus draws liquid and minerals out of the earth?
Answer: mycorrhyzal

With the six consistories, Paul VI continued the internationalization policies started by Pius XII in 1946 and continued by John XXIII. In his 1976 consistory, five of twenty cardinals originated from Africa, one of them a son of a tribal chief with fifty wives. Several prominent Latin Americans like Eduardo Francisco Pironio of Argentina; Luis Aponte Martinez of Puerto Rico and Eugênio de Araújo Sales and Aloisio Lorscheider from Brazil were also elevated by him. There were voices within the Church at the time saying that the European period of the Church was coming to a close, a view shared by Britain's Cardinal Basil Hume. At the same time, the members of the College of Cardinals lost some of their previous influences, after Paul VI decreed, that not only cardinals but also bishops too may participate in committees of the Roman Curia. The age limit of eighty years imposed by the Pope, a numerical increase of Cardinals by almost 100%, and a reform of the regal vestments of the "Princes of the Church" further contributed to a service-oriented perception of Cardinals under his pontificate. The increased number of Cardinals from the Third World and the papal emphasis on related issues was nevertheless welcomed by many in Western Europe.

What type of clothing did Paul VI enact reform on?
Answer: regal vestments

The evolution of the Greek economy during the 19th century (a period that transformed a large part of the world because of the Industrial Revolution) has been little researched. Recent research from 2006 examines the gradual development of industry and further development of shipping in a predominantly agricultural economy, calculating an average rate of per capita GDP growth between 1833 and 1911 that was only slightly lower than that of the other Western European nations. Industrial activity, (including heavy industry like shipbuilding) was evident, mainly in Ermoupolis and Piraeus. Nonetheless, Greece faced economic hardships and defaulted on its external loans in 1826, 1843, 1860 and 1894.

What did Greece do in 1826, 1843, 1860 and 1894?
Answer:
defaulted on its external loans
