What has high inertia but low resilience?
* Tropical forests have high species richness/high inertia but once severely damaged has low resilience. * Grasslands are much less diverse than most forests, and consequently they have low inertia and can burn easily.
How are inertia and resilience related?
Inertia refers to the resistance to dis- turbance of an object or system, whereas the remaining four terms are properties of resilience, which refer to ways in which the disturbed system responds.
What is an example of resilience and inertia in an ecosystem?
Give an example of an ecosystem with high inertia and explain why this is so. Grasslands have high resilience because most of their plant matter is stored in underground root systems, which repair themselves and recover after destruction such as burning. Grasslands can only be destroyed if their roots are removed.
What are the 4 ecosystem services?
The Millennium Ecosystem Assessment (MA), a major UN-sponsored effort to analyze the impact of human actions on ecosystems and human well-being, identified four major categories of ecosystem services: provisioning, regulating, cultural and supporting services.
Does Rainforest have high resilience?
“[L]ooking across different climate models, there is evidence that tropical rainforests may be more resilient to carbon dioxide-induced climate change than previously believed.”
Which biome has very high resilience?
Primary forests are generally more resilient (and stable, resistant, and adaptive) than modified natural forests or plantations.
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.
What keeps ecosystem stable?
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. First is to maintain a diversity of plants and animals in an ecosystem. Humans have a tendency to simplify ecosystems to maximize one particular output.
What is the difference between inertia and resilience in terms of changing ecosystems?
Inertia, the resistance of an ecosystem property to change under stress, is distinguished from resilience, which refers to the degree, manner, and pace of change or recovery in ecosystem properties following disturbance.
What human activities affect the ecosystem?
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
What are the facts about high resilience foam?
Additional High Resilience Foam Facts. How It’s Made. High resilience foam is a polymer created during a chemical reaction between polyol and diisocyanate (two chemicals created from organic compounds).
What is the difference between high and low inertia?
If the inertia is not well matched, the motor’s motion will be very unstable. The low inertia means that the motor is relatively flat and the spindle inertia is small. When the motor is repeatedly operated with high frequency, the inertia is small and the heat is small.
Why are low inertia motors good for reciprocating motion?
The low inertia means that the motor is relatively flat and the spindle inertia is small. When the motor is repeatedly operated with high frequency, the inertia is small and the heat is small. Therefore, low inertia motors are suitable for high frequency reciprocating motion. But the general torque is relatively small.
How does foam affect the lifespan of a seat cushion?
Another important factor is whether the foam is HR (High Resiliency) which recovers its shape better after use. The frequency of use and the size of the people using the cushion will also affect a seat cushion’s lifespan. A foam cushion’s “firmness” has very little effect on the expected lifespan.
