  1. Segregation

  2. Dumping

  3. Composting

  4. Drainage
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Organic waste is broken down by microbes (bacteria) into simpler substances. It is a multi-step process which is closely monitored with measured inputs of water, carbon and nitrogen rich compounds.

In ________ process, solid wastes are dumped in a low lying area and as a result of bacterial action, refuse decreases considerably in volume and are converted gradually into humus.

  1. Segregation

  2. Dumping

  3. Composting

  4. Drainage
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Dumping in low-lying areas involves the decomposition of solid waste through bacterial action, which reduces its volume and turns it into humus over time.

The composting process is carried out by __________.

  1. Psychrophiles - low-temperature microbes

  2. Mesophiles - medium temperature microbes

  3. Thermophiles - high-temperature microbes

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The three types of bacteria work at different temperatures to decompose the organic matter. Psychrophiles work at lowest temperature, around 55-70 degrees Fahrenheit to break down the organic matter. They give off small heat in the process which is sufficient enough for Mesophilic bacteria to begin composting. They prefer temperatures from 70-100 degrees Fahrenheit and give off heat while decomposing. They die when the temperature goes beyond 100 degrees and this is when thermophiles (heat loving bacteria) begin working.
