What event can disrupt a stable ecosystem?
A disturbance can also occur over a long period of time and can impact the biodiversity within an ecosystem. Major ecological disturbances may include fires, flooding, storms, insect outbreaks and trampling.
What makes a stable ecosystem to change?
Stability Important The two key components of ecosystem stability are resilience and resistance. Resistance is an ecosystem’s ability to remain stable when confronted with a disturbance. Resilience is the speed at which an ecosystem recovers from a disturbance.
What are some natural events that could alter an ecosystem?
Earthquakes, landslides, volcanic eruptions and natural bush fires all affect the many different ecosystems on our planet. Initially, these disasters negatively affect the biodiversity of wetlands, forests and coastal systems by causing the spread of invasive species, mass species mortality and loss of habitat.
What are the three main ways ecosystems can be altered?
Humans change ecosystems in many ways, such as habitat destruction, pollution, introduction of invasive species, and overexploitation of species.
Which event might disrupt a stable ecosystem quizlet?
Occurs when a stable and balanced ecosystem (climax community) is disturbed. This disturbance could be in the form a forest fire, flood, change in climate, volcanic eruption, or another disaster.
What type of ecosystem is most stable?
The ocean
The ocean is the most stable ecosystem. It is stable due to its natural liquid nature (saline), dissolved oxygen, light and temperature. Note: An environment is considered to be stable when its structure and function remain unchanged for a long period of time.
What are the two factors that affect ecosystem stability?
Factors influencing ecosystem stability are biotic potential and environmental resistance. This could be in the form of: positive and negative factors of population growth either abiotic or biotic, species diversity that is highly correlated with stability, as well as climate.
How has the environment changed over the years?
1.1 Virtually all of Earth’s ecosystems have been significantly transformed through human actions. Changes have been especially rapid in the last 50 years and today the fastest changes are taking place in developing countries. Ecosystems are particularly affected by large-scale fishing, freshwater use, and agriculture. More…
Are diverse ecosystems more stable?
If diverse ecosystems were, as a consequence, more stable, the answer would be yes. However, stability is not one, simple property of an ecosystem and there is no one, simple relationship between diversity and stability, say ecologists Tony Ives and Steve Carpenter of the University of Wisconsin at Madison.
What are the changes in the terrestrial ecosystem?
In terrestrial ecosystems: land cover change, mainly by conversion to cropland, and the application of new technologies contributing to the increased supply of food, timber, and fiber. Only areas unsuited to crop plants, such as deserts, boreal forests, and tundra, remain largely untransformed by human action.
