what is meant by natural vegetation? how do temperature and rainfall affect its distribution?explain with examples.
Answers
Natural vegetations means plants growing on their own without any human interference such as mining/lumbering. A natural vegetation are refered to ground covered by grass and have plants/trees growing. Certain types of plants/trees have their own natural habitats, on different parts of earth plants/trees have a community grown accoding to their own habitat, which we refer to as ''natural vegetation''. It will also provide food for animals. Natural vegetation such as forests can regenerate after a long time which is called the ''secondary forest''. Natural vegetations are usually related to an ecosystem.
Climate impacts vegetation very directly.
Plants have evolved to fill particular climatic niches. Each species of plant has a range of conditions in which it thrives as well as environmental requirements that must be met if it will survive.
For example, mangoes are tropical plants. They do best in very warm climates which feature no freezes or frosts and high temperatures year-round as well as high moisture potential. You can’t expect to be successful cultivating this fruit in Siberia, for example. But a mango tree planted in Southern India will be quite happy.
Cacti enjoy semi-arid and arid environments and do well in sunny steppes and bright deserts where their drought adaptation allows them to survive where most other plants certainly would not. However, a cactus would drown in some locations too wet and rainy to allow the plant to grow effectively.
Some climates are hostile to plant growth altogether. Polar climates are too cold and frozen to permit the successful growth of any plant life. Other climates are harsh but have enough growing days to permit some amount of plant life. Subarctic climates, for instance, are inhabited by plants that are cold-tolerant.
Like other organisms, plants have adapted to live their lives under particular environmental conditions. Climates establish long-term meteorological regimes that determine the overall environmental conditions in which vegetation can grow.
