Go into the forest and read the answer.

① The forest is a biological community composed of many organisms with trees as the main body. Forest is rich in resources, which can be divided into biological resources and abiotic resources according to their natural attributes. Among them, biological resources can be divided into three categories: plant resources, animal resources and microbial resources. Plant resources include forest resources (trees, shrubs and bamboo) and forest resources in Hefei (algae, lichens, mosses, extinct species and other seed plants, etc.); Animal resources mainly include mammals, reptiles, forest insects, birds and fish. Microbial resources mainly include various fungi, mycoplasma, chlamydia and so on. Abiotic resources mainly refer to forest soil, water and other resources that support forest biological resources. It can be seen that the forest is a rich and colorful resource pool on the earth, and its main part, the forest biological resources, is a renewable resource that can be used continuously.

② Forest resources are the basic resources for human survival. At the same time, the forest also has the ecological value of maintaining life on earth and improving human living environment.

③ Forests can provide wood products and forest by-products to human beings continuously. Wood products mainly include logs, sawn timber, paper pulp, artificial boards, etc. Forest by-products mainly include leaves, flowers, fruits, stems, barks, resins, gums and sap of forest plants, as well as various products provided by economic forests and forest animals and microorganisms. Providing these products for human beings is undoubtedly an important function of forests.

④ Forest is the main regulator of ecological balance. Forests can convert solar energy into chemical energy, inorganic matter into organic matter, an important (Ni incarnation) zone for material and energy exchange between living things and non-living things, and play a central and leverage role in maintaining the overall function of the ecosystem. It can be said that there is no ecological balance without forests.

⑤ forests can effectively conserve water and prevent soil erosion. With its huge canopy, deep litter and developed roots, forests can play a good role in water and soil conservation and reduce surface erosion. According to estimates, the water storage capacity of 5, mu of forest is about 1 million cubic meters. In areas where forests are destroyed or there are no forests, soil erosion is serious, and many rivers and water conservancy facilities are constantly silted up, which often causes floods.

⑥ forests can effectively protect biodiversity. At present, more than half of the 5-3 million species of living things on the earth thrive in forests.

⑦ forests can effectively alleviate the "greenhouse effect". Due to the extensive use of fossil fuels in modern times, the concentration of greenhouse gases such as carbon dioxide and methane in the atmosphere has been rising continuously, causing the "greenhouse effect" on the earth. Each hectare of forest can absorb 2-4 tons of flower beds and release 15-3 tons of oxygen every year.

⑧ 。 According to the research of relevant experts, a forest can absorb more than 7 kilograms of sulfur dioxide every year on average, which can reduce the harm of industrial acid rain; The roadside forest belt in the city can stop the dust, and the dust retention rate is as high as 7%~9%. At the same time, the forest belt can also reduce the noise, and the noise can be reduced by 6~8 decibels after passing through the 3-meter-wide forest belt.

pet-name ruby forests can produce direct economic benefits, and at the same time have huge ecological and environmental effects, which can't be replaced by anything else.

Among them, biological resources can be divided into three categories: plant resources, animal resources and microbial resources. Plant resources include forest resources (trees, shrubs and bamboo) and non-forest resources (algae, lichens, mosses, ferns and other seed plants, etc.); Animal resources mainly include mammals, reptiles, forest insects, birds and fish. Microbial resources mainly include various fungi, mycoplasma, chlamydia and so on. Abiotic resources mainly refer to forest soil, water and other resources that support forest organisms.
