Ways to adapt to their

climatic environment. Equatorial rain forest

The forests are rich and luxurant. Because of the ideal climatic conditions. - with high temperatures aud abuudant rainfall throughout the year, the growth of trees is rapid. As there is no dry seasun, the trees are evergreen. The trees are tall and straight. The branches und leaves appear. near the crown so as to complete for light and air. The leaves are broad with driptips, or glossy or leathery, so ng to shed rain-water or to enable efficient photosynthesis, The height of the trees: requires the development of

for

support. Many of the tall trees are used by climbing

which are also plants, striving to win light or air, or are parasitic for nutrition. There is very little undergrowth except along river banks, because very little light can penitrate the thick foliage to reach the floor. In swampy area where the ground is boggy, the roots are strong and long to support the plants well above the water. In some cases, the roots are aerating for breathing purpose. There is a lack of undergrowth for the absence of light,

ii/ Desert vegetation

Because of the aridity in the desert, the plants are drought resistant known as xerophytes. The plants are usually low. Some of the plants have deep and branched roots to penetrate under- ground in search of water supplies, They develop waxy or thorny leaves, some with sunken stomata to reduce transpiration. Some of the plants have wax covered. fleshy atens to ature water. Some plants have widespread net-work of surface roots to absorb dew moisture. Some plants remain dormant for voting the infrequent rain showers, Their seeds are protected by an impervious coat. Immediately after rain, the seeds germinate and bloom, rapidly complete their life-cycle before dying down. Some planta, which are known as halophilous can thrive on areas of saline soils. iñ. Coniferous forest

The trees are usually conically shaped, with springy or downward sloping branches to prevent excessive accumulation of snow. Since there is low precipitation in the culd tenjerate region, the bark of the trees is usually thick, their leaves are needle shaped so that loss of moisture by transpiration can be reduced. Moreover, the leaves are usually covered by wax to protect against frost damage. Tree trunks

ks are flexible and slender, so that they can stand well against the strong winds. Roots are nвually shallow and widespread, that allow the trees to absorb water above the frozen suh-soil. The seeds are usually protected in cones to suit the severe coldnese, 3. Study the figure below

Answers:

B. Common features of

eitiea..

The cities marked on the map have the following · features in Čommon Location -- In geueral, they

have a coastal or esturine location, commanding the important world's shipping routes. The only exception is an Which is located 10 the uplands of western Java. Most of them have rich hinte; lande. "Origin -- Most of them have

long history of develop- ment started from the Colonial Period, many of them had been colonized by western ......... powers, with the only exccption of Bangkok. Despite the long history. of development, many of them experienced rapid development recently, which may also be resulted from rural-urban migration.

Function Jost of them are good ports, with the only exception at Bandung. Besides serving es good ports, most of them are multi-functional. A good example to be cited is Manila, which is a commercial centre, Industrial centre, route focus and administrative centre as well. Most of them are well-known as they are capital cities, except Bandung, and Surabaja.

Problems of such cities of the developing world.

Due to the rapid urban growth, overpopulation fa the major problem, Food ja not enough and malnutrition is common. Housing is unother problem. In such cities of the developing world, there are usually many squatters, and slums, over-crowding in urban areas forces the dwellers to live in unhygenic conditions.

Sanitation is poor not only because of over-crowdiness, but also because of the lack of water. supply and inadequate waste disposal. Residential land use is found mixed witli industrial ones, the': discharge of gas, sneg and other wastes by factories aud vehicles results in air pollution, water pollution and sound pollution. Such areas are also a safety hazard, fire is most likely to occur.

Since the narrow streets. of the cities constructed in the colonial periods are nut able to cove with the increased traffic flow, traffic congestion and. accidents pose another problem.

Problem of unemployment is also serious. The education of the people in usually low. Many of them are unemployed. Social problems: such as crimes arise. Owing to the aame -reason; administration is difficult,

are usually areas al unrest. There

ia also a lack of general utilities, e.g. schools, hospitals and recreational facilities.
