The biodiversity and species richness has almost exclusively positive effects in every aspect, lot of which are of huge importance and benefit for the humans.
Explanation:
The biodiversity and species richness is basically the amount of species that inhabit a particular ecosystem, while on global level it represents all of the species on the planet. The more species there are on the planet, the better, and vice versa, the less species there are, the worse. The reason for this is that pretty much every species provides some benefits, which are good both for nature and for the humans. The befits can be seen from several different aspects, such as:
- economic
- agricultural
- medicinal
- ecological
The economic benefits are seen in the fact that lot of species are very interesting and attractive to the people, so some sectors, such as the tourism directly depends on the biodiversity in lot of parts in the world. For the agriculture, it is good that the biodiversity is high, as that means that the pests will be naturally regulated by their predators. The medicine is directly dependent on the biodiversity, as it relies on lot of species to produce the medicines, and if they are gone, this industry will crumble. From ecological aspect, the biodiversity and species richness is important because the communities of organisms will remain as they are, function without any problems, and be in prefect balance.

Answer:
C. plagioclase
Explanation:
From the magma silicate crystals are formed successively when the magma temperature reaches the typical melting temperature for each type of crystal. The first crystals formed at high temperatures can then change their composition or dissolve again. In this way the crystals already formed contribute their ions, molecules and atoms to magma and combine again forming new crystals whose melting temperature is lower than that of the first crystals formed. The new crystals are said to be stable at the lowest temperatures set now. These processes of change are called reactions. As several successive reactions occur as the magma temperature decreases the ordered series of reactions is called the BOWEN series in honor of the Canadian scientist who formulated this concept. There are two types of reactions, the continuous reaction and the discontinuous reaction.
<u>
By continuous reaction a crystal formed at high temperatures such as a plagioclase rich in the Ca2 +</u> component gradually varies its composition by replacing a portion of the Ca2 + ions with the Na + ions and a portion of the Al3 + ions with the Si4 + ions. To maintain its neutrality, the replacement of Ca2 + by Na + is coupled with the replacement of Al3 + by Si4 +. The series of continuous reaction starts from the plagioclase rich in Ca2 +, passes through several plagioclase of intermediate composition towards the plagioclase rich in Na +
Answer:
The essential element of geography called physical systems focuses on the study of the Earth’s natural environments and the systems that shape them.
<em>Physical geography studies the layers of the Earth and the connection between them. For example, the interaction between the anthroposphere and the biosphere - the way in which the protection of natural environments is achieved, but in which tourist routes, tourist activities are also integrated.</em>
The answer is - it can not be taken out of the atmosphere.
The nitrogen, even though makes for about 78% of our atmosphere, and is by far the most abundant gas in it, we can not use it because it can not be taken out of the atmosphere as it is. If we take nitrogen in the form as it is in the atmosphere it is useless for both, humans and plants. It has to go through a process of ''fixation'' first before we can actually use it in our food.
