They are found to be very important for the ecosystem, if they were not present in the ecosystem them plant would not be able to get essential nutrients which are necessary for their growth. Because it the decomposers who help in the recycling of carbon and the nitrogen cycle.
Decomposers break down the dead and decayed material into simpler organic matter into carbon dioxide and nutrients.
Example: bacteria, fungi
Answer:
The correct answer will be option-C

Louse-bourne relapsing fever is a disease which is characterised by having the muscle aches and the episodes of fever.
The disease is a vector-borne disease in which the pathogen spirochete <em>Borrelia recurrentis</em> which lives in the gut of the body louse- <em>Pediculus humanus humanus </em>completes its life cycle and when body louse is crushed gets released on to the human skin and thus penetrates the humans. The disease could prove fatal if no treatment is provided at the right time.
Thus, Option-C is the correct answer.

Answer:
b. passive solar heating
Explanation:
Passive solar heating is a system designed to use solar energy (energy from the sun) for the purpose of providing electricity or heat. This system is used in households and offices to absorb, retain and supply heat to the desired location.
This system is termed "passive" because it does not require any external device for conversion of solar energy rather it exploits sun's energy directly. Hence, according to this question, PASSIVE SOLAR HEATING is the form of renewable energy that uses the sun's energy most directly.
