Terms in this set (67) What makes an ecosystem strong and another ecosystem weak in the face of change? … The volume of species, their genetic diversity, and the complexity of the ecosystem form such rich biodiversity in the forest that one species gap won’t cause the system to collapse.
What can cause an ecosystem to fail?
Important pressures contributing to current and future ecological collapse include habitat loss, degradation, and fragmentation, overgrazing, overexploitation of ecosystems by humans, human industrial growth and overpopulation, climate change, ocean acidification, pollution, and invasive species.
What makes one ecosystem strong and another weak in the face of change is the level or amount of <UNK>?
What makes one ecosystem strong and another weak in the face of change? Kim Preshoff details why the answer, to a large extent, is biodiversity.
What are the factors affecting ecosystem degradation and loss?
One of the main causes that contributes to the degradation of ecosystems is the deforestation due to the advance of the agriculture frontier and inappropriate forest exploitation. More lands are deforested for commercial agriculture and live-stock rearing, and due to overexploitation of forest for wood and energy.
Which one that destroys the balance of ecosystem?
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. These impacts every living thing on the planet, which includes us.
What makes an ecosystem strong?
A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). Healthy ecosystems have an energy source, usually the sun. … Decomposers break down dead plants and animals, returning vital nutrients to the soil.
What are the main factors in ecosystem diversity?
Broadly speaking, the diversity of an ecosystem is dependent on the physical characteristics of the environment, the diversity of species present, and the interactions that the species have with each other and with the environment.
What are some environmental factors that can cause changes in ecosystems?
Important direct drivers include habitat change, climate change, invasive species, overexploitation, and pollution. Most of the direct drivers of degradation in ecosystems and biodiversity currently remain constant or are growing in intensity in most ecosystems (see Figure 4.3).
What factors affect ecosystems?
They include factors such as light, radiation, temperature, water, chemicals, gases, wind and soil. In some environments, such as marine environments, pressure and sound can be important abiotic components.
What is depletion of ecosystem?
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution.
How is ecosystem disturbed?
Many ecosystems are influenced by disturbances such as e.g. land-use, fragmentation, fire, floods or storms. … In particular the interaction of different disturbances and between disturbances and other stress factors (such as habitat loss, pollution or temperature change) is not yet well understood and studied.
What happens if the ecosystem is not balanced?
Pollution (air, water and soil) Degradation of natural resources such as soil erosion, deforestation, depletion of wildlife, shortage of energy, degradation of marine ecosystems and depletion of mineral resources.
What happens if ecosystem is disturbed?
Whenever an ecosystem is affected by a substantial disturbance event, individuals and even entire species may be weakened or killed off. Other ecological damages can also occur, such as changes in hydrologic processes or soil contamination.
