We observe that land becomes barren soon after monsoon but next monsoon it flourishes again with varieties we observe in season earlier?
Answers
Answer:
The first organism that appear on the barren land is lichen and moss that require moist soil for their growth which is found in the rainy season.
These plants grow in moist soil but they need water for reproduction which is only possible in monsoon.
The primary succession is then undertaken by the help of small plants and trees which is favored by the rain.
Then when the monsoon goes the plants die due to lack of water and then comes only when the next monsoon comes.
Explanation:
The soil fertility depends on the rainfall of the season because the outer layer of the soil is washed by the rain during one season.
After one season the nutrients present in the external layer of the harvesting soil washed away by the huge rainfall. But in the next season, the external layer of the soil again accumulated by the rainwater layer by layer so the vegetation will take place for the present year.
