Why are plants considered as crucial in the maintenance of balance in the ecosystem?
serg [7]

Plants are very crucial for maintenance of balance of ecosytem as part of the equilibrium and the primary basis for the ecosystem as the producers.

Explanation:

The ecosystem consists of plants with animals and the environment surrounding it. The balance of all three elements is essential for the co existence of the ecosystem. devoid of any or excess of either factor will lead to destruction.

The imbalance so caused will lead to over production or over consumption of the strata in the ecosystem. Plants holds the producer level of the ecosystem which forms the basis to all, if dis-balanced all the factors relying on it will decline eventually and the world will fall.

HELP PLEASE

Answer:

1. Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local.. 2.Mining in the real world can affect society, ecosystems, and the environment of a specific  region because all the minerals that you are looking for won't be right where you want them to be. It is not going to be in the same area. Instead, it will be scattered throughout the mines and you will have to search for them. 3.Students act as mining engineers and simulate ore mining production by using chocolate chip cookies. They focus on the cost-benefit analysis of the chocolate ore production throughout the simulation, which helps them understand the cost of production. As students “mine” with tools such as paperclips and toothpicks, they keep records of their costs—land (cookie), equipment used, cookie size before and after production, and time spent. While the goal is to make as much profit as possible, other costs and goals are taken into consideration—as in real-world mining engineering. For example, mining engineers also consider the resulting amount of destruction to the lithosphere when deciding the best method to obtain ore. Thus, a line item for land reclamation cost is included from the beginning. A provided worksheet serves as a profit and loss statement. 4.Mine reclamation is the process of restoring land that has been mined to a natural or economically usable state. Although the process of mine reclamation occurs once mining is completed, the planning of mine reclamation activities occurs prior to a mine being permitted or started.
