Answer:
the process by which oxygen released into the atmosphere by photosynthetic organisms is taken up by aerobic organisms while the carbon dioxide released as a by-product of repiration is taken up for photosynthesis.
Explanation:
Plants use carbon dioxide in a process known as photosynthesis. During photosynthesis, plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant's leaves. Oxygen moves out of the plant leaf through these same openings
<u>Answer</u>:
This is due to the unequal resource distribution across the land and the distribution of resources depends upon the physical factors like the land and the climatic conditions. Some places are filled with more resources while some are filled with scare resources. The countries which have more resources are wealthy while the countries which do not have that much resources are not wealthy. The metals are also unevenly distributed on the earth’s crust and the most abundant metal is aluminum and silicon. Some of the distracted metals which are found deep in the earth’s crust and then extracted in the ore form from the mines. The most important reason for the uneven distribution of metals in Earth's crust are their physical factors like the climate, land and their topography.
Answer:
Geostrophic wind D) flows parallel to contour lines of upper-air pressure .
Explanation:
Geostrophic wind -
Air parcel generally moves from higher pressure to lower pressure due to pressure gradient force and left or right deflection due to coriolis force. When this deflection takes place a time comes when pressure gradient force and coriolis force becomes equal and the air parcel moves parallel to isobar then the winds are called geostrophic winds .
