<u>Biodiversity</u> is the biological variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.
Biodiversity is important to humans for ecological life support, biodiversity gives a functioning ecosystem that provides oxygen, clear air and water, plant pollutions, pest control, wastewater treatment and lots of ecosystem services.
Answer:
The big number of people fleeing from Syria may have very negative demographic and economic implications for the country.
Explanation:
Syria is a country in war, both with armed forces inside and with armed forces from other countries. The war is going on for quite some time now, and it has led to the devastation of most of the country. Being afraid for their lives and seeing that there wouldn't be good conditions for living in the country for decades to come, millions of people have been on the move.
With millions of people already gone and millions trying to migrate out of the country, Syria will face a very big problem in the future. It is rapidly losing the young and middle aged population, which is the population that is able to have children and it is the population that has the biggest economic contribution. Also, the highly qualified labor force has almost entirely left the country. Apart from the sharp decline in the population, this will also result in a dramatic drop in birthrates, aging population, lack of labor force, brain drain, and the economy will suffer badly, which in turn will result in more people moving out of the country.
Answer:
Option (C)
Explanation:
Coquina is usually defined as a sedimentary limestone rock that is found to be present in the freshwater zones and in the coastal areas. This rock is made up of broken shells that are smaller in size. The rocks can be easily broken down by the constant flowing of sea waves.
This rock is commonly formed in the same way as the other sedimentary rocks, i.e. it is formed by the deposition of sediments carrying these organic remains and eventually undergoes the process of compaction and lithification on the seafloor.
Thus, the correct answer is option (C).
Answer:
It is a simplified view of the earth's rotation because the tilt of the earth's axis with respect to the plane of the earth's orbit means that sometimes sunrise occurs slightly earlier or later along the same longitude.
