The correct answer is cha.

Types in the ecosystem.

Topic: Analysis: Forest ecosystems are distributed in humid areas, with a wide variety of flora and fauna Forests play an important role in conserving water sources, maintaining water and soil, preventing wind and fixing sand, regulating climate, purifying the air, eliminating pollution, etc

Answer: Solution: A:

Wetland ecosystems Wetlands are widely distributed around the world and are ecosystems with rich biodiversity and high productivity on the earth Wetlands are ecosystems with multiple functions on the earth, which can precipitate, eliminate, absorb and degrade toxic substances in advance, so they are known as the "kidneys of the earth". b. Grassland ecosystems are distributed in arid areas, where annual rainfall is very small Compared with forest ecosystems, grassland ecosystems have much fewer species of flora and fauna, and the structure of communities is not as complex as the former. c. Forest ecosystems are distributed in humid areas, with a wide variety of animals and plants Forests play an important role in conserving water sources, maintaining water and soil, preventing wind and fixing sand, regulating climate, purifying the air, eliminating pollution, etc., and are known as "green reservoirs" and "lungs of the earth". d. Lake ecosystem refers to the composition of aquatic organisms in the lake and their living environment, and the lake boundary is obvious; The area is smaller; The phenomenon of water temperature stratification is obvious. The amount of water varies greatly; Succession, slow development, d wrong so chosen: c

Comments: Mastering the characteristics of forest ecosystems is the key to solving the problem.

Forest ecology. The forest bush side state system is distributed in the humid area, and there are many kinds of animals and plants The forest plays an important role in conserving water sources, preserving water and soil, preventing wind and fixing sand, regulating climate, purifying the air, and eliminating pollution, and is known as "green reservoir" and "lungs of the earth".

d test question analysis: the biosphere is a unified whole composed of organisms and the environment, it includes all the organisms on the earth and the entire environment in which they live, so it is the largest ecosystem, it provides nutrients, sunlight, air, water, suitable temperature and a certain living space and other basic conditions for the survival of organisms, suitable for the survival of organisms, is the only home for humans and other organisms The biosphere includes the bottom of the atmosphere, most of the hydrosphere and the surface of the lithosphere Therefore d is correct

The biosphere is a unified whole composed of organisms and the environment, it includes all the organisms on the earth and the entire environment in which they live, so it is the largest ecosystem, and the biosphere is the common home for the survival of human beings and other organisms

Therefore, the front with the selection: d

Question 1: (1 point) (points can be scored if the writing is correct, standardized, neat, and the layout is reasonable, points will be deducted for one wrong word, and no points will be given for two wrong words).
