Uses of Decomposition Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what’s on both sides.
  • Make sure you understand the information on each card. If something’s unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It’s useful to remember specific examples to understand these concepts better.

What is anaerobic decay?

Anaerobic decay is the decomposition of organic matter in the absence of oxygen, carried out by anaerobic bacteria and microorganisms.

Where does anaerobic decay typically occur?

Anaerobic decay usually happens in wet or submerged environments like swamps, marshes, and bodies of water where there is little or no oxygen.

What is biogas and how is it produced?

Biogas is a mixture of gases, primarily methane and carbon dioxide, produced by anaerobic respiration during the decomposition of organic matter without oxygen.

How are biogas generators used?

Biogas generators use anaerobic digestion to convert organic matter, like animal waste or crops, into renewable biogas, reducing waste sent to landfills and providing an alternative energy source.

How does decomposition benefit gardeners and farmers?

Decomposition enriches soil with nutrients, improves soil structure, reduces waste, and decreases the need for synthetic fertilisers. This increases soil fertility and plant growth.

What are the environmental benefits of decomposition?

Decomposition reduces waste, provides natural fertilisers, and lowers reliance on synthetic fertilisers, making it environmentally friendly and sustainable.
