When the rocks are removed from a desert's ecosystem, the animals that depend on those rocks for homes would be in trouble. If these animals died due to predators and a lack of homes, then the other animals (predators) that depend on them for food would start to need other sources of food. This would cut into another predator's food supply and so on.
<u>Reasons for the presence of a high amount of water in the human body:</u>
Options A, B, E
Water is the main component for any living being, especially humans.
The structure of cells uses water as a building component. Water is responsible for the transportation of nutrients within a cell. It plays a vital role in the regulation of our body temperature. The internal temperature of the body is maintained by water as per the external temperature.
Hence, humans sweat in hot weather conditions to prevent overheating of the body.
Water also helps in removing the waste materials from our body. The waste is excreted mainly in the form of urine. Apart from that, water also makes it easy to pass solid waste material from our bodies.
The United Nations Conventions on the Law of the Sea (UNCLOS) declares that seabed area, which does not fall under the jurisdiction of a particular country, is a common natural heritage. The minerals of this area can be usd by anyone. Due to vast presence of sea area, and conflicting boundaries, as well as illegal mininig practices, the imposition of such laws is difficult. The very large sea areas which should not be mined, should be restrained under non mining region. But, mineral-greedy nations are not following such instructions.
The envrionmental implications of ilegal seabed mining includes, destabilisation of oceanic systems, effect on microbial systems of the sea, and danger to the creatures living in the hydrothermal vents, which are not used to light exposure.
