Question

Dense evergreen vegetation of broad sclerophyllous leaves and shrubs with fire resistant resinons plant is known as:
(A) chaparral vegetation
(B) savannah vegetation
(C) steppe grassland
(D) tundra vegetation

Answer 1

Hint: Every place has its own vegetation depending on the climates prevailing there. Vegetations are further divided into different categories as well. Based on the place of growth plants have adapted various morphological means.

Complete Step by Step Answer:
A vegetation community known as chaparral is typically made up of shrubs with stiff stems and leathery leaves. There might also be cacti. A large number of different plant and animal species are safeguarded when the Chaparral is preserved. Toyon, chamise, poison oak, scrub oak, Yucca, as well as various shrubs, trees, and cacti, are some examples of the flora that can be found in chaparral. Plants including myrtle, hawthorn, and broom grow in the maquis. Compared to these other varieties of chaparral, the Australian mallee is more open and primarily made up of dwarf eucalyptus trees.

Scrub, grasses, and sporadic trees make up the savanna vegetation, which is found near water sources such as aquifers, seasonal rivers, and water holes. Animals and plants must adjust to the extended dry spells. Many plants, such as the acacia tree with its tiny, waxy leaves and thorns, are xerophytic. Numerous varieties of short grasses that often grow in sparse bunches make up the typical steppe vegetation. All gradations of cover, from semidesert to woods, are present on the steppe, which also occasionally supports sporadic shrubs and small trees. Since there is typically little ground cover, a lot of soil is exposed. Dwarf shrubs, sedges, grasses, mosses, and lichens make up tundra vegetation. Some tundra environments support sporadic tree growth. The term "tree line" or "timberline" refers to the ecotone (or ecological boundary zone) that separates the tundra from the forest. Nitrogen and phosphorus are abundant in the tundra's soil.

The prevalent climatic conditions in a specific area heavily influence how plants are distributed. The varying climatic conditions have resulted in the establishment of numerous regions with distinct plant communities. A shrubland or heathland plant group known as chaparral is mostly found in Mexico. The chaparral biome is located below this region, which has a Mediterranean climate and a high risk of wildfires. Summer drought-tolerant plants with hard sclerophyllous evergreen leaves are found there, in contrast to the Coastal sage scrub community, which has soft, drought-deciduous leaves.

So, option (A) is correct.



Note: Grasslands are different from forests. Nearly half of all known species on Earth are found in forests, which make up about a third of the planet's surface. Grasslands, which are a mixture of various grass species, legumes, and herbs, are most common in areas where there is not enough regular rainfall to support the growth of forests but not so little as to cause desertification.
