Which Of The Following Is An Example Of Secondary Succession?

After a successful start up of our original nature preserve, it was struck with a natural disaster. The natural disaster killed off all of the animals that live in the preserve. Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. An example of secondary succession is a volcanic eruption, an area where a volcano erupts, lava may cause some damage to the plant and tree life. Over a span of years, however, if there was land that had been affected by the eruption but not necessarily covered in new volcanic rock, the seeds and plant parts and roots in the soil could renew. This change is due to shifts in the presence and relative abundance of different species as …show more content…
This needs to happen fairly quickly because there is only a thin layer of soil that’s called the active layer, thaws and refreezes each year. This makes the nutrient cycle possible, the nutrients move from the environment to a living organism and then back to the environment. Eventually small animals such as the arctic hare will eventually come into the area and eat the grass that is available for them. In the next step of succession the hares will be eating by wondering animals such as arctic foxes and snow owls that are looking for food in the nearby area and they would find potential mates in the area and reproduce. In the step after that the animals would be eaten by a number of animals that are wandering in the area for food and for shelter some of those animals are polar bears and wolves. The animals would eventually find mates and reproduce in the area. the area's population would continue to grow and …show more content…
one of the ways carbon goes from the geosphere to the atmosphere is by fossil carbon. This is because people burned up the fossil carbon which then reaches the atmosphere. Then it leaves the atmosphere by plant respiration and bacteria. Then it is mixed with marine and land ecosystems through organisms. In the biosphere all land living organisms contain organic carbon. Also microorganisms single celled algae and chemoautotrophic bacteria make an importance of converting atmospheric CO2 into terrestrial carbon. Carbon is associated in some way with organic carbon by photosynthesis or by a living organism that eats plants and algae. And some carbon is released by respiration while the rest stays in the tissue. When an organism dies the bacteria breaks down the tissue and releases CO2 back to the atmosphere and into the dirt.
Nitrogen in the nutrient cycle starts with the element nitrogen in the air. Two nitrogen oxides are found in the air as a result of interactions with oxygen. Nitrogen in the air becomes a part of biological matter mostly through the actions of bacteria and algae in a process known as nitrogen fixation. Water erosion of the earth will carry the nitrogen into the hydrosphere. Nitrogen moves through the geosphere by animals dying and decomposing into the
