Which factor can disrupt nutrient cycling in an ecosystem?

Disruption of nutrient cycling in an ecosystem is significantly influenced by pollution and habitat destruction. These factors can lead to an imbalance in the nutrient dynamics that sustain ecosystems. Pollution, such as chemical runoff from agriculture, can introduce excess nutrients like nitrogen and phosphorus into water bodies. This can trigger problems such as algal blooms, which consume oxygen and can lead to dead zones, harming aquatic life and disrupting the natural cycling of nutrients.

Habitat destruction, such as deforestation or urbanization, alters the landscape and the organisms that live there. It can reduce biodiversity, which is essential for maintaining a balanced ecosystem. Decomposers, such as fungi and bacteria, play a crucial role in breaking down organic material and recycling nutrients back into the soil. If those organisms are diminished due to habitat loss or pollution, the entire nutrient cycling process can become impaired.

In contrast, regular rainfall, balanced ecosystem diversity, and natural decomposition processes all contribute positively to nutrient cycling. Regular rainfall helps to replenish water in the ecosystem, supporting plant growth and facilitating the movement of nutrients. A balanced ecosystem diversity ensures that all roles in the nutrient cycling process are filled, promoting resilience and stability. Natural decomposition processes are crucial for breaking down organic matter and returning essential nutrients to the soil, fostering
