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: "How are nutrients recycled?"

- no

Problem: To protect its seagoing interests and trade routes, Portugal established strategic garrisons in Goa (India), Malacca (East Indies), and Hormuz in the Persian Gulf. Portuguese explorers then embarked upon Macau (now Macao), the Congo, and various other parts of Africa, including the Sudan. The Portuguese policy was to avoid armed strife and to develop a trade empire, rather than to conquer nations. To this end it succeeded with relatively few blood-soaked episodes in its colonial history. Adventures abroad, however, proved disastrous during the second half of the 16th century. In 1557 the 14-year-old boy-king Sebastiao ascended the throne, the beginning of a calamitous reign that was to end at the battle of Alcacer-Quiber (Morocco) in pursuit of a vain crusade. Sebastiao's untimely demise, alongside some 18,000 ill-prepared, badly led followers, set the stage for a crisis of succession. For many years afterwards, legends and rumors bizarrely insisted that the king was still alive, and imposters turned up from time to time claiming the throne; those who were plausible enough to be deemed a threat were summarily executed. In fact, the only rightful claimant to the crown was the elderly Prince Henry. But after two years of alternating between the throne and his sickbed, he died, heirless. Surveying the situation and smelling an opportunity, Spain occupied the power vacuum, and Portugal's neighbor and long-time antagonist became its master. Spanish rule dictated Portugal's inadvertent involvement in Spain's ongoing wars. In 1587 a squadron of British ships commanded by Francis Drake attacked the Algarve (now a "legitimate target" as Spanish territory) and sacked Sagres, thus depriving the world of the relics of Henry the Navigator. Nine years later Faro was torched. The 1386 Treaty of Windsor, by which Britain and Portugal had pledged eternal friendship, seemed a distant memory. Portugal's empire was gradually eroded, and many of its trading posts (with the notable exception of Brazil) were picked off by the British and Dutch. Finally, after 60 years of Spanish rule, Portuguese noblemen (aided by the French, then at war with Spain) organized a palace coup and restored independence. The Great Disaster Portugal's greatest misfortune struck on All Saint's Day, 1 November 1755.

Question: "Before the restoration of Portuguese control, what Portuguese holdings were taken over by the British and the Dutch?"

Answer: "Goa (India)"

OPTIONS:
- no
- yes
Answer: no

Question:
When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison. After reading the above, is "Wet lands, and prairies" the correct answer to the question "What types of land have been lost to agriculture?"? OPTIONS:
- no
- yes

Answer:
yes
