There is self-regulation within the ecosystem. The more complex the structure and the greater the number of species, the stronger the self-regulation ability. As a result, tropical rainforest ecosystems are more self-regulating.
-
Forest ecosystems and rainforest ecosystems are two different systems that grow in different environments and maintain different biological systems, which are not comparable. Both systems are equally vulnerable to human destruction.
-
The biological chain of tropical rainforest is complex, the animals and plants are relatively intact, and the factors that suffer the least from human disturbance. It is more self-regulating.

The more complex the composition of the ecosystem, the stronger the stability of resistance and the weaker the stability of resilience.

Tropical rainforest. There are two types of ecosystem stability: resistance stability and resilience stability.
The more ecosystem components, the more complex the food web, and the more complex the flow of energy and the more complex the flow of energy, the less the impact of a single change in the natural environment or human factors of the same degree will be on it, because the upstream of the affected person's food chain will be restricted by other organisms of the same level, and the downstream can be compensated by other ways, that is, the resistance is stable. This represents the tropical rainforest ecosystem.
Conversely, the fewer components in an ecosystem, the more homogeneous the food web (sometimes as simple as a food chain), the more significant and potentially devastating the impact on one of its components. The destruction of a component will cause a disconnect between the upstream and downstream, and the upstream may over-reproduce, and the downstream may cause population decline due to the lack of food**. That is, its resistance stability is weak.
The representative ecosystem is the grassland ecosystem.
I guess the ability to adjust probably refers to the stability of resistance

Is your ability to regulate a bit vague? At least there has to be a condition to compare.

Tropical rainforests are one of the most biologically productive ecosystems in the world, and their biological productivity varies due to differences in the geographical location, soil properties, rainfall, and other conditions of each tropical rainforest. In general, tropical rainforests use about 70% and 80% of the assimilated energy for self-sustainment (respiratory metabolism) and about 20% and 30% of the assimilated energy for net production, with an average annual net production of about 22 mtn ha, which is equivalent to a multiple of the annual net production of temperate forests (13 mtn ha) and a double of the annual net production of boreal coniferous forests (8 mtn ha). Tropical rainforests have about the same timber productivity as warm hardwood forests, but can convert more of the purified production into foliage and fruit.
Tropical rainforests are balanced by their internal circulation. Nutrients leached from leaf clusters and epiphytes are quickly absorbed and re-introduced into the plant, while unabsorbed nutrients are also captured by fungal cords and mycorrhizal fungi. In the tropical rainforests of the Ivory Coast in Africa, more than 60% of potassium and 15% of 56% of other nutrients are recycled by the rain that falls on the ground.
After the dry season, when the leaching intensity reaches its maximum, the soil roots will absorb nutrients such as potassium, calcium, magnesium and nitrogen from the rainwater leached from the plant body and leaves.
Soil roots are highly dependent on mycorrhizal fungi, which can transport nutrients from dead organic matter directly to living roots, minimizing the possibility of nutrients being leached into the soil. This allows mineral nutrients to be trapped in both living and dead organic matter. The concentration and rapid recycling of nutrients in the uppermost soil explains why, when forests are cleared for agricultural land, the soils are generally poorer and harvested only in a few years.
Climatic characteristics. Areas where tropical rainforests are distributed have high annual rainfall, usually above 1,800 mm and in some places as much as 3,500 mm. The rainfall is evenly distributed throughout the year, and it is humid all year round, and the relative humidity of the air is more than 95%.
The average precipitation is more than 2032 mm per year, which is more than the annual evaporation. There is no significant seasonal variation, with temperatures generally around 30 during the day and about 20 at night.
Geographical location. Tropical rainforests are mainly found in the jungle areas of South America, Asia, and Africa, and most of them are located between the northern and southern latitudes (i.e., the area between the Tropic of Cancer and the Tropic of Cancer). In tropical rainforests, there are usually three to five layers of vegetation with trees up to 150-180 feet high that are covered like tents.
The density of the vegetation in the lower layers depends on how much sunlight penetrates the trees in the upper layers, and the more sunlight that comes in, the greater the density.
Topography. The topography of the rainforest region is complex and varied, from lowland plains with rocky hills to highland canyons with streams. The landscape creates a rainforest landscape with many forms.
In the forest, quiet ponds, rushing streams, and cascading waterfalls are everywhere; Towering trees, tangled vines, and lush flowers and plants are intertwined into a green labyrinth.

An evergreen forest biome rich in thick-stemmed vines, woody and grassy epiphytes that occur naturally in the warm and rainy tropics. The superior and stable environment provides the best conditions for the survival and development of tens of thousands of biological species. Tropical rainforests grow mainly in the humid tropical lowlands with an average annual temperature of 24 or more, or the coldest month with an average temperature of 18 or more.
The temperature is generally around 30 degrees Celsius during the day and about 20 degrees Celsius at night.
In terms of climate type, a certain amount of tropical rainforest can be formed under tropical rainforest climate, tropical oceanic climate and tropical monsoon climate, and the tropical rainforest formed under tropical rainforest climate is the most typical.
Because the conditions for the formation of tropical rainforests are high temperature and rainfall, in addition to the equatorial region to meet the conditions, there are also non-zonal factors:
The causes of the tropical rainforest on the eastern side of the island of Madagascar are: the eastern side is located on the windward slope, and the abundant precipitation brought by the southeast trade winds; Mozambique's warm current warms and humidifies.
The tropical monsoon forests in southwestern China and the Indochina Peninsula are caused by precipitation from the southwest monsoon from the northern Indian Ocean and the southeast monsoon from the western Pacific.

A habitat for a variety of animals, in addition, tropical rainforests also have a material use to provide timber for production and life.
The rise and fall of tropical rainforests is not only related to the future of biological resources, but also closely related to global climate change. At present, the indiscriminate deforestation of tropical rainforests is becoming more and more intense, which has aroused great concern among the people of all countries. The most pressing issue for the protection of the biosphere, or the protection of nature, is the protection of tropical forests, especially tropical rainforests.
The stability of the ecosystem includes resistance stability and resilience stability. The simpler the trophic structure of the ecosystem, the lower the stability of resistance and the higher the stability of resilience, and the more complex the nutrient structure of the ecosystem, the stronger the stability of resistance and the weaker the stability of resilience. >>>More
