Answer: 2) secondary succession
Explanation:
Ecological succession is the change in the biotic community of the ecosystem due to the changes occurring in the abiotic components such as water, soil, atmosphere and others. These changes occur with respect to time until the ecosystem attains the stability.
A secondary succession can be define as the changes which occur after a catastrophic event or ecological disturbance. Such changes brings stability with the help of precursors of previously existing species at the same place.
According to the given situation, secondary succession could have occurred this is because of the fact that the forests fire can burn the vegetation in an area. The burn sites will regrow into a healthy forests because of some of the precursors of previously existing plant species like seeds, stem, roots and others which will help in regrowth of new plants.
Answer: 30 year
Explanation:
The normal high temperature for a given day determined by the temperature of a place averaged over a period of time, often 30 years. This is also described as climate information. Climate information includes the statistical weather information that tells us about the normal weather, and also the range of weather extremes for a location. Most weather forecasters rely of past weather to predict the normal high temperature of a given day.
The average high or low temperature is the normalized high or low temperature for at least a 30 year period. Therefore, an average high is a statistical average. Records need to be kept at least 30 years for an average high temperature, for the information to be statistically meaningful.
Answer:
The Niger River will be heavily exploited in the future so that it helps the economies in people in the region.
Explanation:
Most of the big rivers around the world are heavily exploited. They have huge dams built on them for multiple purposes, canals that connect places that don't come out on the rivers, transportation, and travel are well organized and on a high scale. The Niger River though is not that exploited despite having huge potential, but that will change in the near future for sure.
This river goes a long way in the interior of Western Africa and the outskirts of Central Africa. It can support boats, and it is the major factor that supports agriculture. Considering that this part of the world is in a dire situation but develops quickly, the Niger River will be used for sure. Huge dams will be made, and the water will be used for the production of electric power to feed the economies, but also for irrigation as the region is mostly semi-arid, for drinking, and for the industry. In order to boost the economy and help in the development of the large urban areas, canals will be made to the ones that are not located at the river's banks. Transportation through the river's waters will skyrocket as it will be fast, safe, and cheap.
Tourism is the LARGEST industry in the world.
