The four causes of ecosystem disturbance include natural events, such as wildfires, floods, and storms; human activities, such as deforestation, urbanization, and pollution; invasive species that disrupt local flora and fauna; and climate change, which alters habitat conditions and species interactions. These disturbances can lead to significant changes in biodiversity, ecosystem function, and resilience. Understanding these causes is crucial for effective conservation and management strategies.
Catastrophic disturbance refers to a sudden and severe event that causes significant disruption or damage to an ecosystem, resulting in long-lasting consequences for the plant and animal populations within that ecosystem. Examples include hurricanes, wildfires, volcanic eruptions, and tsunamis.

The original climax community in an ecosystem is more likely to be restored after a natural disturbance, as it allows for the ecosystem to recover and return to its pre-disturbance state through natural processes. Human-caused disturbances often result in more significant and long-lasting impacts that may prevent the restoration of the original climax community.
A disturbance that harms some organisms but does not significantly impact the overall ecosystem is known as a "sublethal disturbance." This type of disturbance may affect individual species or populations without causing long-term ecological changes or degradation to the habitat as a whole. Examples include localized pollution events or specific predation pressures that impact certain species but allow the ecosystem to maintain its structure and function.

Decomposition is not a disturbance of the ecosystem. This is because it is a natural process in harmony with the ecosystem rather than an outside force is interfering.

Small disturbance
secondary disturbance
A landslide or volcanic eruption is a kind of primary disturbance. It causes a very drastic and sudden change in the landscape.

A primary ecological disturbance will be the one which will directly affect the ecosystem. For example flood, volcanic eruption, earthquake. A secondary ecological disturbance will be the one which will indirectly affect the ecosystem.

The term for this disturbance is "habitat destruction" or "ecosystem degradation". It can result from factors such as deforestation, pollution, urbanization, or natural disasters, leading to a decline in biodiversity and ecosystem health.
