Why is decomposition of vegetable matter considered exothermic?

This is exothermic because the pile releases heat as the microbes in the pile release energy as heat when they compost the matter. -Super Llama


Why does compost give off heat?

The byproduct of the compostable materials being broken down into the elements from which they're made is the reason for the heat in a compost pile. The breakdown of compostable materials into compost is brought about by the food that these materials represent to microbes. The microbes give off heat in digesting their food.The situation is similar to human body temperature rising due to the change from stored to motion energy when human muscles are exercised. Human sweat helps regulate human heat. There's no such equivalent for microbes.So microbes warm up, and may even do so to the extent that the compost pile catches on fire. You don't want the compost pile on fire. But you do want it at a maximum temperature of 140 degrees F/60 degrees Celsius. The heat keeps weed seeds and pathogens from growing.


Can yeast go into compost?

Yes, yeast can go into your compost pile.


How is heat generated within a compost heap?

Air trapped by the compose material is continually heated by the sun, which over time elevates the temperature of the compose pile


Can you compost honey?

Yes. You can add honey to a compost pile. However, one of the reasons for a compost pile is to encourage the natural bacteria to decompose the organic material. Since honey is a natural antibiotic and anti-bacterial agent, adding too much honey may not have the results you desire.

Where does the energy in a compost pile come from?

Carbon is the source of energy in a compost pile. Compost piles need to have brown and green materials, which are respectively carbon- and nitrogen-rich. Green materials provide the pile's decomposition-friendly micro-organisms with proteins.


What is the process of a compost heat?

The process of compost heat is to breack down the material.


What type of heat energy does a compost pile release?

Chemical, microbial, physical, and solar sources are behind the type of heat energy which a compost pile releases. A compost pile's carbon- and nitrogen-rich recyclables interact with environmental oxygen and sunlight. Potential or stored energy is released by the temperature-coded feedings of macro- and micro-organisms within the pile, with chemical decomposition effected by actinomycetes and aerobic bacteria and fungi and physical by ants, beetles, centipedes, earthworms, flatworms, flies, millipedes, nematodes, rotifers, slugs, snails, sowbugs, spiders, and springtails.

What is the difference between compost pile and compost pit?

A compost pile is compost in a pile or heap. a compost pit is compost in a pit or hole in the ground.


Bad for compost?

Plastic is bad for compost because it throws the heat of in the pile and can cause a spot to spoil


Why would the mitochondria be a compost pile in your house?

They wouldn't, a mitochondria provides energy for the cell, whereas a compost pile doesn't do anything besides provide fertilizer for your garden


Why is a compost pile an analogy for the mitrochondria?

The creation of energy is a reason for why a compost pile is an analogy for the mitochondria. A compost pile makes dark-colored, fresh-smelling, nutrient-rich organic matter by breaking down carbon- and nitrogen-rich recyclables through the interactions of air, heat, macro- and micro-organisms, and moisture. The mitochondria turns nutrients in animal and plant food into adrenosine triphosphate (ATP) to generate the chemical energy for sustaining life.


What is the difference between a compost heap and a compost pit?

A compost heap is a pile of composting material that is in a pile on the ground. A compost pit is dug into the ground and the composting material is placed in it.
