Ecosystems with simple structures must have high resilience and stability?

Ecosystem. Due to its self-regulating ability, it has a certain stability. There are two kinds of stability in ecosystems, one is resistance stability and the other is resilience stability, generally speaking, the strength of the two types of stability is negatively correlated, when an ecosystem has a more complex trophic structure, it contains biological communities.

The higher the species richness, the stronger the stability of resistance and the weaker the stability of resilience. Just like forests and farmland, forests have stronger resistance stability than farmland, and resilience stability is weaker than farmland. Once the forest and farmland are destroyed, it becomes a wasteland, thus beginning secondary succession.

From the wasteland reenactment to herbaceous plants.

The stages are used for a short period of time; It takes quite a long time to go from wasteland to forest communities. Because the more complex the nutrient structure of an ecosystem, the more time and difficulty it will take to recover to its original level after being damaged, so the less stable its resilience will be.

When discussing resilience and stability, we need to consider environmental factors, not simply the trophic structure of ecosystems.

For example, in tundra ecosystems in summer and winter, tundra resilience is more stable in summer than in winter because of the right environmental conditions such as moisture and sunlight in summer.

Another example is desert ecosystem and grassland ecosystem, the trophic structure of desert ecosystem is simpler than that of grassland, but due to the harsh environmental conditions of desert, it will take longer to recover even if the components are simple, so its resilience stability is lower than that of grassland.

3.Resilience and resilience stability of ecosystems.

Here's how to improve the stability of the ecosystem:

1. Control the degree of disturbance to the ecosystem, and the use of the ecosystem should be moderate, and should not exceed the self-regulation capacity of the ecosystem.

2. Cutting down trees in the forest in an appropriate amount will not destroy the structure and function of the forest, and can also promote the renewal of the forest.

3. The scientific and reasonable livestock carrying capacity will not destroy the grassland, and stable livestock products can be obtained.

4. Moderate fishing of adult fish in the marine system can not only promote the renewal of marine fish resources, but also continuously obtain various products.

5. For ecosystems with high human utilization intensity, corresponding material and energy inputs should be implemented to ensure the coordination of the internal structure and function of the ecosystem.

The components of ecosystems: abiotic matter and energy, producers, consumers, decomposers. Among them, the producer is the main ingredient.

Different ecosystems are divided into forest ecosystems, grassland ecosystems, marine ecosystems, freshwater ecosystems (divided into lake ecosystems, pond ecosystems, river ecosystems, etc.), farmland ecosystems, tundra ecosystems, wetland ecosystems, and urban ecosystems.

Among them, the inorganic environment is the foundation of an ecosystem, and its conditions directly determine the complexity of the ecosystem and the richness of the biological communities in it. The biome reacts to the inorganic environment, and the biome in the ecosystem is not only adapting to the environment, but also changing the appearance of the surrounding environment, various basic substances closely link the biome with the inorganic environment, and the primary succession of the biome can even turn a desolate bare land into an oasis with abundant water and grass.

The various components of the ecosystem are closely linked, which makes the ecosystem an organic whole with certain functions.

Resilience refers to the ability of an ecosystem to return to its original state after being damaged by external disturbances. For example, when rivers are heavily polluted, a large number of aquatic organisms are killed, and the structure and function of river ecosystems are destroyed.

"Resistance stability" is a professional term in biology and ecology, which is proposed to qualitatively describe the resistance of an ecosystem to external changes, and is related to the "resilience stability" of Sakura. Resistance stability refers to the ability of an ecosystem to resist external disturbances and keep its structure and spinal functions intact.

Influencing factors: Resistance stability is related to resilience stability, and ecosystems with high resistance stability have low resilience stability. Generally speaking, the more complex the constituent species, the stronger the biological chain, and the tighter the ecosystem, the higher the stability of resistance and the lower the stability of resilience.

Summary. Hello, it is a pleasure to serve you. The ability of ecosystems to resist disturbance and maintain the original state of system structure and function is one of the important ways to maintain the stability of ecosystems.

The stability of resistance is related to the status of the development stage of the ecosystem, and the more mature its development, the more complex the trophic structure, and the stronger the ability to resist disturbance.

Hello, it is a pleasure to serve you. The ability of ecosystems to resist disturbance and maintain the original state of system structure and function is one of the important ways to maintain the stability of ecosystems. The stability of resistance is related to the chaotic stage of ecological Suixun phylogenetic development, and the more mature its development and the more complex the trophic structure, the stronger the ability to resist interference.

Fellow, I really didn't understand, I can be more specific.

Good. There are certain differences in the performance of the stability of the two ecosystems in Tuansheng. In general, the more components in the ecosystem, the more complex the food web, the stronger its self-regulation ability, and the higher the stability of resistance.

Conversely, the less stable or wanton it is. To improve the stability of the ecosystem, on the one hand, it is necessary to control the degree of disturbance to the ecosystem, and the utilization of the ecosystem should be moderate, and should not exceed the self-regulating capacity of the ecosystem; On the other hand, for ecosystems with high human utilization intensity, corresponding material and energy inputs should be implemented to ensure the coordination of the internal structure and function of the ecosystem. Hope it helps, thank you!

Ways to improve ecosystem stability: increase system complexity, increase species populations, and avoid species homogenization and degradation of system production capacity caused by unconstrained species (producers and primary consumers without natural enemies).

System stability refers to the ability of an ecosystem to resist changes and disturbances in the external environment and to maintain system balance.

The more complex the species composition, the more stable the structure, the more complete the function, and the higher the production capacity of an ecosystem, the higher its self-regulation ability. This is because the decline of species often leads to a decrease in the productivity of the high-friendly system, and a decrease in the ability to resist natural disasters, invasive alien species and other disturbances.

In ecosystems with high species diversity, there are species with similar ecological functions but different responses to the environment, so as to ensure that the entire ecosystem can adjust itself to maintain various functions due to environmental changes. Therefore, species-rich tropical rainforest ecosystems are more self-regulating than species-rich cropland ecosystems.

Characteristics of the ecological balance:

1. The input and output of energy and matter are basically equal, and the types and quantities in the biological community remain relatively stable.

2. Producers, consumers, and decomposers form a complete nutritional structure.

3. Henghuai has a typical food chain and a pyramid-shaped trophic level that conforms to the law.

Ecosystems have the ability to self-regulate, which is the basis for ecosystem stability. The stability of an ecosystem refers to the ability of an ecosystem to maintain its own structure and function relatively stable, as well as the ability to return to its original equilibrium state after a certain amount of disturbance.

Ecosystems have the ability to self-regulate, which is the basis for ecosystem stability.

Biodiversity plays an important role in maintaining the stability of ecosystems and reflects its indirect value.

The coordination of the internal structure and function of the ecosystem can improve the stability of the ecosystem.

The self-regulating capacity of an ecosystem depends on the diversity of components, i.e., diversity leads to stability. Generally speaking, the more complex the composition of the ecosystem, the more species of organisms, and the stronger the self-regulation ability, the higher the stability of the ecosystem. Therefore, forest ecosystems are more self-regulating than desert ecosystems.

However, there is a limit to the self-regulating capacity of ecosystems, and if human intervention or changes in natural factors exceed this limit, the stable state of the ecosystem will be disrupted.

Characteristics of ecosystems in a stable state (characteristics of ecological balance) 1) The types and quantities of producers, consumers, and decomposers in the ecosystem remain relatively stable.

2) Have a relatively stable food chain and food web.

3) The input and output of materials and energy among the components of the ecosystem should be relatively balanced.

3.The stability of the ecosystem includes aspects such as resistance stability and resilience stability.

4.The size of the ecosystem's ability to self-regulate.
