Question

What are the limitations in obtaining energy from (a) wind (b) wave and tidal energy?
What is the role of decomposers in the ecosystem?​

Answer 1

Answer:

The wind:

1. Wind energy farms can be established only at those places where wind blows for the greater part of a year. 2) The wind speed should also be higher than 15 km/h to maintain the required speed of the turbine.

3)Limitations of extracting waves energy: The waves are generated by strong winds blowing across the sea. Wave energy would be a viable proposition only where waves are very strong.

Answer 2

Answer:

Limitations in obtaining energy from both wind and wave and tidal energies are that they are limited to certain places.

Wind energy is commercially obtained in areas of high wind.

Wave and tidal energy is available in coastal areas only.

Decomposers are essential in decomposing the wastes and hence cleaning the ecosystem.
