Basically, the rhizosphere effect is a grouping of soil properties that change when in the effective vicinity of roots. Some of these effects are increased number of organisms (mostly bacteria and fungi) and decomposition rates.
greenhouse effect
Effect - The heavy rainstorm hitting the farm is the effect.
the greenhouse effect is a global phenomenon.
The greenhouse effect is the natural way that the Earth keeps warm. Too many extra greenhouse gases turn the greenhouse effect into an enhanced greenhouse effect. The enhanced, or accelerated, greenhouse effect is causing global warming.
This effect is called the Coriolis effect. It influences the path of winds and ocean currents, causing them to curve to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

rhizozhere is region of soil around the roots of the plants
--"it is a plant root" not really A rhizoid is a "root-like" structure found on non-vascular plants like mosses and liverworts. A rhizome is the bundle of stems that is partially underground and the roots form on in a vascular seedless plant like a fern. A rhizome absorbs water and minerals by producing rhizoids, which are unicellular hair-like structures grown off the rhizome, which absorb these.

The rhizosphere contains many bacteria that obtain nutrients (proteins and sugars released by the roots)and food from sloughed off plant cells (rhizodepositation).
The term "Rhizosphere" was introduced in 1904 by the German scientist L. Hiltner to denote the region of soil, which is under the influence of plant roots.Rhizosphere is defined as the region of the soil immediately surrounding the roots of a plant together with the root surfaces.Plant roots receive between 30-60% of the net photosynthesized carbon. Of this, an estimated 40-90% enters the soil as a wide variety of materials including alcohols, ethylene, sugars, amino acids and organic acids, vitamins, nucleotides, polysaccharides, and enzymes. These materials create a unique environment for soil microorganisms, called the rhizosphere. The plant root surface, termed rhizoplane, also provides a unique environment for microorganisms, as these gaseous, soluble, and particulate materials move from the plant plant to soil.The rhizosphere effect is beneficial to the plants in two ways, firstly it helps in providing nutrients to the plants and secondly, it helps the plants in combating root diseases;Here, soil environment may be aerobic or anaerobic. And here Bacteria predominate rather than fungi.Mainly soil bacteria present:Achromobacter, Pseudomonas, Bacillus, Clostridium etc.Fungi such as: Aspergillus flavus, A. niger, Cladosporium herburum, Fusarium oxysporum, and F. solani.Rhizosphere microorganisms are directly associate with root system, i.e, no vector is needed.- Tathagata Bhattacharjee.student of M.Sc -1st year,B.R.S.N College,West Bengal State University.

Yes, plants roots release weak organic acids that can help dissolve minerals in rocks. This process, known as rhizosphere acidification, can contribute to the weathering of rocks and release of nutrients that plants can then absorb.
Yes, Price effect = substitution effect + income effect
