Why are some ecosystems more fragile than others?
High rates of species turnover or population fluctuations characterize fragile ecosystems, and vice versa. The diversity of ecological processes related to these changes makes ecosystem fragility a central evaluation criterion in conservation management.
What are the two factors affecting the ecosystem?
The environment includes two types of factors: abiotic and biotic.
- Abiotic factors are the nonliving aspects of the environment. They include factors such as sunlight, soil, temperature, and water.
- Biotic factors are the living aspects of the environment.
What are the cause of destruction?
Once the land is scarred by mining efforts it is left vulnerable to massive erosion. Other events and issues such as natural disasters, war, the construction of dams, and poverty in developing countries also contribute to the destruction of tropical rainforests.
What destroys the balance of an ecosystem?
In an ecosystem, each organism has its role and purpose. … When we introduce external factors such as too much carbon dioxide or methane, it destroys the balance of the ecosystem which in turn affects those who live in it. The result is global warming, water shortage, extinction of species, etc.
Are all ecosystems fragile?
The only observable fragility is that displayed as a result of disturbances, natural as well as human-caused, operating in the ecosystem. … The diversity of ecological processes related to these changes makes ecosystem fragility a central evaluation criterion in conservation management.
Which of the following ecosystem is most fragile?
Coral reefs are one of the most diverse ecosystems on our planet, but they are also one of the most fragile. Susceptible to coral bleaching, climate change, and other forms of pollution, all we can do now is watch and hope for a miracle. Protecting our oceans has become a more common trend than we think.
Why island ecosystems are very fragile?
island ecosystems are especially vulnerable to climate change because island species populations tend to be small, localized, and highly specialized, and thus can easily be driven to extinction ; Coral reefs, which provide a number of services to island people, are highly sensitive to temperature and chemical changes …
What are biotic factors that affect an ecosystem?
The biotic factors in an ecosystem are the other organisms that exist in that ecosystem. How they affect an individual organism depends on what type of organism it is. The other organisms (biotic factors) can include predators, parasites, prey, symbionts, or competitors.
What are some environmental factors that can cause changes in ecosystems?
Some environmental factors that can cause changes in ecosystems are extreme weather, disease, land use change, invasive species, and pollution. Explain how changes in land use can impact an ecosystem.
