What is most likely to result immediately after a rainforest Brainly? The answer would most likely be secondary succession, because primary succession already occurred the first time things moved in.
What is most likely to result immediately after a rainforest in Brazil is clear cut quizlet?
What is most likely to result immediately after a rainforest in Brazil is clear-cut? secondary succession. The number of rhinoceroses has decreased to near extinction. How are rhinoceroses classified under the Endangered Species Act? endangered.
Which type of process first occurred in the ecosystem around Mount Saint Helens after it erupted?
At Mount St. Helens, erosion cut through the new volcanic deposits and exposed soil where plants could sprout. Thus in this disturbance, erosion was a positive process for plants, improving habitat. Lakes, streams, and forests responded at different rates after the 1980 eruption.
What would result in primary succession?
Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier.
Why is clear cut more damaging than forest fire?
Why is a clear cut (every tree has been cut down and removed) more damaging to a community than a forest fire? Forest fires leave some species behind as well as topsoil & seeds. With clear cutting, soil can be lost/microclimate can be changed causing original community to not regroup.
What is most likely to result immediately after a rainforest?
What is most likely to result immediately after a rainforest Brainly? The answer would most likely be secondary succession, because primary succession already occurred the first time things moved in.
What factors might result in a primary succession quizlet?
Occurs when an organisms colonizes a lifeless habitat. The development of plant and animal life in an area where NO ecosystem previously existed. Eventually primary succession will lead to equilibrium. Primary occurs on lava flow, rocks, cliffs and Sand dunes.
What type of vegetation would you expect to find on newly formed volcanic islands *?
On newly created volcanic islands, for example, after the rock cools, seeds blown by the wind may lodge in crevices, germinate, and take root. Often these first colonizing plants are weedy species, such as fast-growing grasses and lichens, that do not grow tall but do reproduce quickly.
What was the aftermath of Mt St Helens?
57 people lost their lives and hundreds of homes, buildings and structures were destroyed. After the eruption, the summit of Mount St. Helens was gone, forests were obliterated and rivers followed new courses. More than 150 new lakes and ponds were formed, and existing lakes filled with sediment, flooding their banks.
What caused the destruction of the Mount St Helen ecosystem?
Forty years ago, after two months of earthquakes and small explosions, Mount St. Helens cataclysmically erupted. A high-speed blast leveled millions of trees and ripped soil from bedrock. The eruption fed a towering plume of ash for more than nine hours, and winds carried the ash hundreds of miles away.
What kind of ecological succession would wildfires result to?
secondary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals recolonize a habitat after a major disturbance—such as a devastating flood, wildfire, landslide, lava flow, or human activity (e.g., farming or road or building construction)—
What does secondary succession start with?
Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site. Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession.
Which organism was the first to colonize the area after the eruption?
Primary succession occurs after a volcanic eruption or earthquake; it involves the breakdown of rocks by lichens to create new, nutrient -rich soils. The first species to colonize an area after a major disturbance are called pioneer species; they help to form the new environment.
What can live on bare rocks?
Lichens — a combo of fungus and algae — can grow on bare rocks, so scientists thought that lichens were some of the first organisms to make their way onto land from the water, changing the planet’s atmosphere and paving the way for modern plants.
Can a plant really grow in hardened lava?
Can a plant really grow in hardened lava? It can if it is very hardy and tenacious. It begins with a plant that must be able to grow on new land with minimal soil or nutrients.
Which cause results in the most extinctions?
There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption.
Which of the following disturbances would result in primary succession?
Examples of disturbances that cause primary succession include retreating glaciers, volcanic eruption and the erosion of sand dunes. Human activity can also be a cause of primary succession, such as the creation of a paved surface. These types of disturbances leave bare rock exposed or otherwise accessible.
What is the main role of pioneer species during primary succession?
In primary succession, pioneer species must be organisms that can live on bare rock. … Along with wind and water, the pioneer species help weather the rock and form soil. Once soil begins to form, plants can move in. The first plants are usually grasses and other small plants that can grow in thin, poor soil.
Which factors involving the activities of people are a threat to biodiversity?
The human population requires resources to survive and grow, and those resources are being removed unsustainably from the environment. The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and the introduction of exotic species.
