Problem: Living things need non-living matter as well as energy. What do you think matter is used for? One thing is to build bodies. They also need it to carry out the processes of life. Any non-living matter that living things need is called a nutrient. Carbon and nitrogen are examples of nutrients. Unlike energy, matter is recycled in ecosystems. You can see how in Figure 3.11. Decomposers release nutrients when they break down dead organisms. The nutrients are taken up by plants through their roots. The nutrients pass to primary consumers when they eat the plants. The nutrients pass to higher level consumers when they eat lower level consumers. When living things die, the cycle repeats.

Question: "What happens to nutrients when the decomposers use them to break down dead organisms?"

Answer: "The nutrients are taken up by plants through their roots, pass to primary consumers when they eat the plants, and pass to higher level consumers when they eat lower level consumers"

Question:
Among the early blows struck for independence was a rebellion in the town of Olhao. On 16 June 1808, the townsfolkarmed with little more than ancient swords, spears, and stonesattacked and captured the local French garrison. It's said that a party of local men then set sail from Olhao all the way to Brazil, without maps or navigational aids, to tell the king of the insurrection. The real battle, however, was waged under the leadership of the Duke of Wellington, whose coalition forces expelled the French after two years of bitter fighting. The war left Portugal further weakened, and in 1822 its major empire outpost, Brazil, declared independence. At the same time, a dispute over the crown continually raged between Pedro IV, the absentee monarch who preferred to reign as Emperor of Brazil rather than return to Portugal, and his brother Miguel. The power struggle, with strong overtones of absolutism versus liberalism, excited the interest and intervention of other powers. With British help, Pedro defeated Miguel off Cape St. Vincent in 1833, and his expeditionary force marched to Lisbon. Pedro took the throne, though armed struggle continued for months and the lingering bitterness long after that. By 1892 Portugal, racked by wars and the continuing expense of maintaining its African colonies (including those of Mozambique and Angola), declared itself bankrupt. The seeds of discontent with absolutist rule were sown. Kingdom's End Bloodshed would haunt the remaining years of the Portuguese monarchy. On 1 February 1908, the royal family was riding in an open carriage along the Lisbon river front plaza, Terreiro do Paco, when an assassin opened fire and killed King Carlos and the heir to the throne, Prince Luis Filipe. The prince's younger brother, Prince Manuel, was also hit, but he survived and was thus propelled to the throne at the tender age of 19. Amid republican agitation, a surprise uprising led by elements within the armed forces deposed Manuel in 1910. Having ruled for less than three years, Manuel died in exile in 1932 in England. The sudden end of more than seven centuries of monarchy brought confusion and crisis to the country. Presidents and prime ministers were ushered into and out of office an unbelievable 45 times between 1910 and 1926, until a military revolution suspended Portugal's problematic democracy. After reading the above, is "32" the correct answer to the question "How old was Prince Manuel when he died?"? OPTIONS:
- no
- yes

Answer:
no

Input: Fossils can be used to match up rock layers. As organisms change over time, they look different. Older fossils will look different than younger fossils. Some organisms only survived for a short time before going extinct. Knowing what organisms looked like at certain times also helps date rock layers. Some fossils are better than others for this use. The fossils that are very distinct at certain times of Earths history are called index fossils. Index fossils are commonly used to match rock layers. You can see how this works in Figure 2.30. If two rock layers have the same index fossils, then they're probably about the same age.
"How are index fossils useful?" is "They are used to identify extinct animals"?

OPTIONS:
- no
- yes
Output: no

Input: The new administration had already begun exploring possible diplomatic options, retracing many of the paths traveled by its predecessors.U.S. envoys again pressed the Taliban to turn Bin Laden "over to a country where he could face justice" and repeated, yet again, the warning that the Taliban would be held responsible for any al Qaeda attacks on U.S. interests. The Taliban's representatives repeated their old arguments. Deputy Secretary of State Richard Armitage told us that while U.S. diplomats were becoming more active on Afghanistan through the spring and summer of 2001, "it would be wrong for anyone to characterize this as a dramatic shift from the previous administration." In deputies meetings at the end of June, Tenet was tasked to assess the prospects forTaliban cooperation with the United States on al Qaeda. The NSC staff was tasked to flesh out options for dealing with the Taliban. Revisiting these issues tried the patience of some of the officials who felt they had already been down these roads and who found the NSC's procedures slow." We weren't going fast enough,"Armitage told us. Clarke kept arguing that moves against the Taliban and al Qaeda should not have to wait months for a larger review of U.S. policy in South Asia." For the government," Hadley said to us,"we moved it along as fast as we could move it along." As all hope in moving the Taliban faded, debate revived about giving covert assistance to the regime's opponents. Clarke and the CIA's Cofer Black renewed the push to aid the Northern Alliance. Clarke suggested starting with modest aid, just enough to keep the Northern Alliance in the fight and tie down al Qaeda terrorists, without aiming to overthrow the Taliban. Rice, Hadley, and the NSC staff member for Afghanistan, Zalmay Khalilzad, told us they opposed giving aid to the Northern Alliance alone. They argued that the program needed to have a big part for Pashtun opponents of theTaliban. They also thought the program should be conducted on a larger scale than had been suggested. Clarke concurred with the idea of a larger program, but he warned that delay risked the Northern Alliance's final defeat at the hands of the Taliban. During the spring, the CIA, at the NSC's request, had developed draft legal authorities-a presidential finding-to undertake a large-scale program of covert assistance to the Taliban's foes.
"Who thought the program should be larger?" is "Rice, Hadley, and Zalmay Khalilzad"?
