Answer:
b. Yes, the average efficiency is 10%
Explanation:
The average efficiency at each trophic level is 10% because there is about 10% of energy is transferred from one trophic level to another. In some trophic levels the efficiency of organisms is 20% but in most of the trophic level has 10% efficiency so that's why the average efficiency is 10%. Yes, this ecosystem obeys the Lindeman's Law for ecological efficiency due to its 10% of ecological efficiency.
It helps us survive. We can survive more time without food than without water
The best answer is "foreshocks before the quake and aftershocks after the quake".
These terms are used to characterise the events of an earthquake over time. Foreshocks are small shocks that can occur before the main seismic event. Aftershocks, like foreshocks, are smaller seismic events that can occur after the main seismic event.
Answer:
Tundra
Permafrost
Only plants with shallow root systems grow in the Arctic tundra because the permafrost prevents plants from sending their roots down past the active layer of soil. ... Some of the plants that live in the Arctic tundra include mosses, lichens, low-growing shrubs, and grasses--but no trees.
The cold climate of the alpine tundra is caused by the low air temperatures, and is similar to polar climate. Alpine tundra is distinguished from arctic tundra in that alpine tundra typically does not have permafrost, and alpine soils are generally better drained than arctic soils.
The tree line is the edge of the habitat at which trees are capable of growing. It is found at high elevations and high latitudes. Beyond the tree line, trees cannot tolerate the environmental conditions.
