Does soil require energy for metabolism?
The short answer is: No, soil is never metabolized so energy is not required for its metabolism. More specifically: By definition, only living organisms metabolize anything. And, when they do, energy is always required. But the metabolism of soil never occurs as soil itself contains no nutrient and remains undigested and is excreted unchanged when a living organism ingests it. Two examples of ingesting soil come to mind among higher organisms: Earthworms do eat some wet soil so as to extract vegetable matter from it, but they metabolize only the latter and excrete the soil unchanged and therefore not metabolized. Elephants are also known to eat some soil from which their organism selects useful bacteria to keep but excretes the soil undigested and therefore not metabolized. Among lower organisms, plants do not ingest soil but extract soluble minerals and electrolytes from it through their roots and metabolize these using energy.
How does soil structure affect the characteristics of soil?
Soil structure affects the characteristics of soil in many ways. Some soil is not good for farming if it is too rocky. Other soil is perfect for farming and needs little more than regular tending to yield good crops. Different soils yield different organisms as well.
What happens to dead plants and animals?
It is recycled by organisms known as decomposers
What are some vocabulary words for soil?
A Horizon, B Horizon, C horizon, bedrock, decomposers, earthworms, fertile soil, gardeners horizon, insect larvae, litter, moles, northern forest soils, organisms, plant roots, soil horizon, texture, weathered rock
What is the organic layer of soil?
So far this is what I think organic soil means. The soils are chemically fetilized and ammonia and other synthetics are harming the soil. Organic soil is chemical-free, not harming the soil nor the environment.
What factors affect the thickness of the horizons and the composition of the soil?
I think this is the answer: Some soil organisms mix the soil and make spaces in it for air and water. Other soil organisms make humus, The material that makes soil fertile.
What provides minerals for plant growth and a habitat for some organisms?
the soil or earth
What is the importance of the organisms found in soil?
actually they create some spaces in between the particles of the soil so that air can pass in and out through the particles ans thus maintains the fertility of the soil. Ex- Earthworm.
How do you kill soil organisms?
Heat is often used to sterilize soil. For small amounts it can be heated in an oven. For larger opererations there are large steamers that heat the soil and kill off weed seeds as well as micro-organisms. Chemical methods, such as fumigation, are also used in some agricultural practices. Heat is often used to sterilize soil. For small amounts it can be heated in an oven.

Which organisms are included in the genus of Fusarium?
In the Fusarium genus, the organisms are mostly branching fungi. They are plentiful in soil. Some of these fungi are pathogens, while others are used in production of food.
Which layer of earth contains humus?
It's the layer of organic matter in soil. The organic matter largely is built up by the death and decay of organisms that live in soil. Some such organisms include bacteria, beetles, earthworms, and moles.

Which decomposers are key decomposers in the soil?
The FOUR soil decomposers are.. -Bacteria -Worms -Organisms -Fungi
How do animals affect each other in the soil?
Some soil organisms mix the soil and make spaces in it for air and water. Other soil organisms make humus, the material that makes soil fertile. As for plants, the roots of flowers, a tree, weeds, grass etc. all break up the soil and hold it into place.

What are the components of the valley ecosystem?
Some of the components of the valley ecosystem includes water, soil and the rocks.
You are a fouth grader please list some nonliving organisms that you can Understand?
For something to be an organism, it needs to have been alive at some point... There is no such thing as a non-living organism (except if you count viruses, but it is debatable whether they are organisms or not).
