13. With the massive amount of plant life, ample rainfall and favorable temperatures, you might think
that tropical rainforests would be large net producers of oxygen, and yet surprisingly, they are not! With
your knowledge of photosynthesis and cellular respiration, can you explain why this might be true?
Think about what happens when a leaf drops or fruit from a tree is eaten.

Answers

Answer:

Tropical rainforests such as the Amazon have been said to produce so much of Earth's oxygen when in fact this is not necessarily true.

Plants do indeed use Carbon dioxide during photosynthesis and the end product is Oxygen. The amount of oxygen produced however is more or less equivalent to the amount of Carbon dioxide taken in as atoms cannot be multiplied. With Carbon dioxide comprising only 0.04% of air, the oxygen produced is not as much as one would think.

After these trees produce Oxygen, they will also use it during respiration to produce energy which means that they would be sucking in most of the oxygen that they created. This would therefore reduce the net oxygen coming from these trees.

Another thing is that when plant life dies and is decomposed, the carbon dioxide that it stored from will be released back into the atmosphere. Leaves falling and fruits eaten will have this effect as well and since this happens a lot in tropical rainforests, their net oxygen production decreases.

1. Drowning, suffocation and carbon monoxide poisoning can lead to death because they all prevent
oxygen from reaching our cells. Explain how this lack of oxygen can lead to death; be specific about how
this lack of oxygen can affect cellular metabolic processes.

Answers

Answer: Lack of energy

Explanation:

Oxygen is needed in a process known as Respiration where it is used to produce energy from glucose. This energy is what the cell uses to continue whatever functions that it carries out which are needed for the body to survive. If the cells don't get oxygen, they can't make energy and if they can't make energy, they die.

Some cells are more important than others and so will need a constant supply of oxygen. The brain for instance requires 20% of the oxygen used in the body. If the body suffers from a lack of oxygen for whatever reason, brain cells begin to die within about 4 minutes.

The brain is extremely important as it directs the body. If the cells there begin to die, the body deteriorates and the body stops engaging in certain processes due to a lack of direction from the brain. This coupled with the other cells dying around the body will lead to even more deterioration till the body dies.

Volcanoes eruption when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts.

When Melting takes place?

Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another. Volcanoes are the large volcanic buildings with long, and generally the conical shape, usually with a small crater on the summit and the steep flanks, that constructed by the interleaving of lava flows and the pyroclastic products emitted by one or more conduits.

Compound volcanoes are present in all regions of the volcanism, but it has in the plate convergence zones, where the tectonic plate subdows plunges toward the earth's mantle beneath another tectonic plate, that these volcanic buildings are the most abundant.

The magmatic expression of a converging plate margin environment is usually a series of sub-regularly spaced Compound Volcanoes, forming a sub-parallel volcanic arch to the tectonic fossa.
