actually the soil tropical rainforests is very poor there are several reasons for the poor soil of tropical rainforests:

• The soil is highly acidic. The roots of plants rely on an acidity difference between the roots and the soil in order to absorb nutrients. When the soil is acidic, there is little difference and therefore little absorption of nutrient from the soil.
• The type of clay particles present in tropical rainforest soil has poor ability to trap nutrients and stop them from washing away even if human artificially add nutrients to the soil. The nutrients mostly wash away and are not absorbed by the plants
• The high temperature and moisture of tropical rainforests causes dead organic matter in the soil decompose more quickly than in other climates, thus releasing and loosing its nutrients rapidly
• The high volume of rain in tropical rain forests washes nutrients out of soil more quickly than in other climates.

In photosynthesis the carbon dioxide is absorbs by the plants and the oxygen is released. It does not add carbon dioxide to the carbon cycle. In respiration oxygen is converted to tissues and cells and the oxidation products, carbon dioxide and water are given off. The most abundant gas typically released into the atmosphere from volcanic systems is water vapour, followed by carbon dioxide and sulfur dioxide. A composting process convert organic matters into stable compost that is odor and pathogen free, and a poor breeding substrate for flies and other insects and releases carbon dioxide.
