Answer: A
Explanation:
Ecological succession is the process of change in the species structure of an ecological community over time. The time scale can be decades (for example, after a wildfire), or even millions of years after a mass extinction.
Answer: D - Eukaryotic
Explanation: Can not be A, B or C
- Prokaryotic cells can not make up multicellular organisms
- Bacterial cells are prokaryotes and unicellular
- Not all multicellular organisms are plants and are therefore not all made of plant cells
Answer:
Explanation:
A sequence of flowing lava, pyroclastic flows, volcanic eruptions, caldera-forming events, and earthquakes changed the landscape of Yellowstone forever. The pressure exerted by the magma chamber has resulted in measurable ground deformation in certain parts of Yellowstone known as resurgent pressure domes.
Fire Activity also causes the Yellowstone to change. As the number of very large wildfires and total acres burned annually increases, there is an increasing frequency of warm spring and summer temperatures, reduced winter precipitation, and early snowmelt in the Western United States during the last 20 years.
In 1995, the wolf population increased in Yellowstone, causing the deer population to decrease and to change their behavior. When threatened by wolves, deer graze less and move about to aerate the soil.
In the 70 years since the wolves left Yellowstone, the entire ecosystem had collapsed into chaos, with coyotes running riot, and elks overgrazing willows and aspens. Without those trees, songbirds declined, beavers could not build their dams, and riverbanks eroded.
Answer: Examples of prokaryotes are bacteria and archaea.
Explanation:
<em>At noon the sun is directly overhead the sun rays fall vertically on the body so the shadow is very short.</em>
<em>So the rays fall vertically on the body. in mornings and evenings the rays fall at inclined position. So shadows are long at mornings or evenings.</em>
