***Birth is actually a kind of agglomerative group living, a tendency to optimize the state of existence, towards the group nature of the higher and higher with the stage of evolution, ****Birth union is more like a conscious rationalization of the phenomenon. Such as family union, group union, intergroup union, racial union, national union. Convergent living reduces physical energy expenditure.

This opens up the possibility of intellectual evolution (- the brain consumes a lot of energy, and without saving energy it cannot dominate the development of the brain), and the natural consciousness of the tendency to conformity is impressed with the group moral nature. ***Biological properties are essential properties of human beings, and the roots of human thought and morality come from them.

. p>The most typical examples are lichens formed by mycorrhizal ****growth, in which fungi such as ascomycetes ****growth with green algae, and ****growth of fungi with cyanobacteria (formerly known as blue-green algae or cyanobacteria). The green algae or cyanobacteria carry out autotrophic photosynthesis to provide organic nutrients for the fungi, while the fungi carry out heterotrophic life, decomposing rocks with the organic acids they produce, thus providing mineral elements for the algae or cyanobacteria.

Rhizobium-plant ****life. Includes many common species of rhizobacteria and leguminous plants, as well as other non-leguminous plants (Alder, Prunus, Tea, etc.) and Frankia actinomycetes, etc.

These are the most common species of rhizobacteria.

Mycorrhizal fungi and plants. Most plants in nature have mycorrhizae, which have the function of improving plant nutrition, regulating plant metabolism and enhancing plant disease resistance.

Some plants, such as the seeds of orchids will not germinate without mycorrhizal fungi, and seedlings of azaleas will not survive without mycorrhizal fungi. Mycorrhiza has two major categories, ectomycorrhiza and endomycorrhiza, the latter can be divided into six major subtypes, but the most important is the cotyledonary mycorrhiza.
