Answer:
Producers
Explanation:
Organisms who make (or produce) their own food are called producers, <em>plants are capable of self-feed through the process of photosynthesis, therefore, they are producers.</em> These producers are the first energy source for primary consumers and the star of the living food chain. Consumers are animals that consume other organisms, they are divided into three categories: primary (herbivores), secondary (carnivores and omnivores), tertiary consumers (they consume energy from all other levels). The final link in this food chain is the decomposers, also known as detritivores, they eat decaying or dead matter including dead plants or animals, returning vital nutrients to the soil.
Biomagnifiers are organisms that tolerate increasing concentration of a substance at successively higher levels in a food chain. A bioaccummulator is an organism that suffers a net accumulation of a contaminant from all sources including water, air, and diet. Biomagnifiers and bioaccumulator can be from plants to animals all across the food chain.

Answer:
Fertility Rate
In the UK, the fertility rate has been below replacement levels since the early 1970s. The average fertility is presently 1.94 but there are regional differences within this, with Scotland’s fertility rate currently 1.77 compared with 2.04 in Northern Ireland. There is also a shift to higher mean pregnancy ages – women giving birth in 2009 were on average one year older (29.4) than those in 1999 (28.4).
There a lot of factors that have contributed to this change. These include improved availability and effectiveness of contraception; the rising costs of living; increasing female participation in the labour market; changing social attitudes; and the rise of individualism.
Work and Pensions
Longer retirement periods may lead to an increased level of pensioner poverty, especially amongst those who have not been able to pay into occupational schemes. Women are particularly vulnerable to this. They have a higher life expectancy than men and can lose their husband’s pension support if he dies first. They are also more likely to have taken time out of the labor market to raise children or care for others, meaning they may not have saved enough for their retirement.
In response to this, the UK government recently announced plans to remove the fixed retirement age meaning that employers can no longer force people to retire once they reach 65. They have also announced plans to increase the retirement age for women from 60 to 65 by 2018. It will then be raised to 66 for both men & women by 2020. Employers are also being encouraged to employ older workers and specialist initiatives are being put in place to support older people in returning to work.
Life Expectancy
As medicine advances and older populations are healthier, they will live longer and thus the population as a whole will age.

Answer:
Option D: Handel's Messiah is a sacred oratorio.
Explanation:
Oratorio is defined as a large-scale narrative musical work for orchestra and voices, especially on sacred theme. Handel composed Messiah in 1741 which is an English-language oratorio. Handel in early years of his work established himself for his work for Italian opera but later in 1730's he turned into English oratorio because of the change in public taste. Messiah was his sixth work which he had composed for modest vocal and instruments, however, after his death this work is adopted on much larger scale with giant orchestra and choirs.
Although natural resource consumption tends to e lower in developing nations there is often worse environmental degradation because there are weak environmental regulations in place to protect the environment. Additionally major industries fail to institutionalize environment saving policies. Also there is often ineffective waste management systems as well that create problems for the environment as well.
