How is decay useful to plants?

Decaying leaves are nature’s compost: they help to form organic matter in the soil, and they provide nutrients to plants and decomposers (such as invertebrates, bacteria and fungi) on land and in water (Webster, 2007). Biodiversity plays an important role in these processes.

What happens to dead organisms and waste products?

When a plant or animal dies, it leaves behind energy and matter in the form of the organic compounds that make up its remains. Decomposers are organisms that consume dead organisms and other organic waste. They recycle materials from the dead organisms and waste back into the ecosystem.

What do decaying plants and animals give out?

Back to the Beginning. When plants and animals die, they become food for decomposers like bacteria, fungi and earthworms. Decomposers or saprotrophs recycle dead plants and animals into chemical nutrients like carbon and nitrogen that are released back into the soil, air and water.

What type of living thing is the main organism involved in decay?

The main groups of decomposer organisms are bacteria and fungi. Bacteria are single-celled microscopic organisms. Fungi are often larger organisms that include moulds and mushrooms. They both cause decay by releasing enzymes which break down compounds in their food so it can be absorbed by their cells.

Which conditions are needed for decay?

There are five necessary conditions or factors for good decomposition:

  • Organic material: plant or animal material to decay.
  • Water: the right amount of moisture.
  • Oxygen: air must be able to get to the material.
  • Warmth: the temperature cannot be too hot or too cold.
  • Decomposers: bacteria or fungi are needed to do the job.

What conditions increase the rate of decay?

As the temperature increases, decomposers become more active and the rate of decay increases. When decomposers break compost down, the compost heap becomes warmer due to the respiration of the bacteria and fungi generating heat. At extremely high temperatures decomposers will be killed and decomposition will stop.

What is the main reason for mixing compost?

Once spread on the soil, compost is broken down into minerals by decomposing bacteria and fungi, as well as by other organisms, such as worms. Adding compost helps to recycle minerals so that they are absorbed by new plants and used in growth.

What is garden soil used for?

Garden soil is the cheapest way to enrich the soil in gardens and flower beds. You can also use garden soil as an ingredient in homemade potting soil. Yes, some people want soil in their potting soil. Just be sure to add nutrients and amendments to make the mix light and loose.
