Answer:

Options (A), (B) and (C)

Explanation:

In an ecosystem, the transfer of nutrients takes place from one place o another. This input and output of nutrients continuously takes place in the ecosystem.

  • The rainwater is also essential as it carries a certain amount of valuable nutrients such as calcium, fluoride, magnesium, and iron that are mixed with water, and this enriches the fertility of the soil and the water is taken up by the roots of the plants for the growth and expansion of plants.
  • The nitrogen-fixing bacteria refers to those micro-organisms that are present in the soil and helps in the conversion of the atmospheric nitrogen into nitrogen compounds, which are helpful for the enhancement of the soil fertility.  
  • Chemical weathering usually refers to the process by which the rocks disintegrates due to the effect of chemical reactions. The micro-organisms and the plant roots release some acids sometimes that react with the rocks and help in breakdown releasing the nutrients that are stored in the rocks. This eventually mixes up with the soil and increases the quality of the soil.

Thus, the correct answers are options (A), (B) and (C).
