The elimination of an organism in an ecosystem takes out all balance. There may be an overpopulation of some organisms, and an underpopulation of others. For an example, if rabbits were taken out of the food chain, there would be an overpopulation of grass, and underpopulation of what eats rabbits.
Many impacts can be brought by global warming, here I would introduce two impact each on the aspect on ecosystem and agriculture.
On ecosystem:
1. Shift in distribution of plants:
The changes in climate brought by global warming will alter the natural distribution limits for vegetation. For example, forests are moving north into the ;and that was once Arctic tundra, while the growing season increased in northern high latitudes.
2. Extinction or endangerment of species
Species may not be able to cope with climate change unlike human, hence intolerance of the increasing temperature may led to the extinction of spices. For example, coral reef cannot survive under temperature over 30 degree Celsius hence facing the danger of extinction.
On agriculture:
3.Farm production lowered
A warmer climate would lead to a loss of soil moisture hence increasing the erosion rate, and the dry soil will lower the land productivity as crops cannot grow on these barren land, especially water thirsty crops such as rice.
4.Farm production destroyed
Pests may become more active given the shorter and warmer winter, while floods may be present more often given the rapidly rising sea level and the instability of the climate.

Answer:
root wedging
Explanation:
Due the tropical climate, there will be presence of trees which will aid rooting wedging in Weathering of rocks
<span>During
the flow of the river, water force gets remains alongside the riverbanks. As
the water hits a larger body of water, the force in its flow became slow and
the sediments it picks up settled on the lowest point of the riverbed. During
the time Mississippi River and the Gulf of Mexico hits each other, sediments
are deposited and it created the South Louisiana land. In order to use this process
to rebuilt wetlands, dredged material from the Mississippi River must be used
to create alteration pipelines of sediments. This process replicates the building
process of original land and sediments deposition. </span>
