Which of the following decreases during ecological succession? ? species diversity, biomass, niche specialisation, humus, net community productivity?

Question

Answer

Humus because it is the garbage produced by the plants and when more area covered by plants then less humus is produced

Answer

Net Community Productivity decrease during ecological succession......!

Answer

Can u pls explain. .??

Answer

Ecological Succession

Ecological succession refers to the gradual change in the structure and composition of an ecosystem over time. It occurs in response to disturbances or the natural progression of ecological communities. As succession progresses, several factors change, including species diversity, biomass, niche specialization, humus, and net community productivity.

Species Diversity

During ecological succession, species diversity typically increases. In the early stages of succession, pioneer species, which are often adapted to harsh environmental conditions, colonize the area. As succession progresses, new species, such as shrubs and trees, begin to establish themselves. This leads to an increase in the number of species present in the ecosystem. However, as the succession reaches a climax community, the species diversity may stabilize or even decrease as dominant species outcompete others.

Biomass

Biomass refers to the total mass of living organisms in an ecosystem. During ecological succession, biomass generally increases. In the early stages of succession, pioneer species with rapid growth rates and high reproductive capacities dominate. As succession progresses, larger and more complex organisms, such as trees, replace the early colonizers. These larger organisms contribute significantly to the overall biomass of the ecosystem.

Niche Specialization

Niche specialization refers to the adaptation of species to specific ecological niches or roles within an ecosystem. During ecological succession, niche specialization tends to increase. In the early stages, pioneer species often have broad ecological tolerances and can occupy a wide range of niches. However, as succession progresses, different species develop specific adaptations and become more specialized in their resource requirements and ecological roles.

Humus

Humus refers to the organic component of soil formed by the decomposition of organic matter. During ecological succession, the accumulation of humus generally increases. As pioneer species grow and die, their organic matter contributes to the development of soil. Over time, the continuous input of organic material from decomposing plants and animals enriches the soil with humus, improving its fertility and nutrient content.

Net Community Productivity

Net community productivity (NCP) refers to the overall rate of biomass production in an ecosystem. During ecological succession, NCP typically increases initially and then stabilizes. In the early stages, pioneer species rapidly colonize and establish themselves, leading to a higher rate of biomass production. However, as succession progresses and the ecosystem becomes more mature, the rate of biomass production may reach a plateau or decline as the system approaches a climax community.

Conclusion

During ecological succession, species diversity generally increases, biomass accumulates, niche specialization becomes more pronounced, humus accumulates in the soil, and net community productivity initially increases and then stabilizes. These changes reflect the dynamic nature of ecosystems as they progress from disturbance to a more stable state.
