A city is supplied by water from local wells. The city discharges its treated wastewater into the ocean.The city uses 25,000 liters of water per person per year. Precipitation falls in the amount of 25,000 liters per person per year.



Is the city using its water supply in a sustainable manner?

A)yes
B)no

Answers

Answer:

B)no

Explanation:

Sustainable use of water means use of water to fulfil various human needs for water without having any negative impact on the environment.

The sustainable use of water allows a minimum of 20 to 50 litres of daily water per person to fulfil their water needs, that means 600 litres maximum per person per year but in the given situation the city uses 25,000 litres of water per person per year.

This shows that people in the city are not using water sustainably which is causing a fall in precipitation.

Hence, the correct answer is "No".

What is the role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem

Answers

Answer:Cellular respiration in plants and animals involve chemical reactions with oxygen that release stored energy. ... Plants, algae, and many microorganisms use the energy from light, carbon dioxide from the atmosphere, and water to make sugars (food) through the process of photosynthesis, which also releases oxygen.

Explanation:

hope it helps :)

The role of photosynthesis and cellular respiration in the cycling of matter and the flow of energy through the ecosystem is the following:

The fundamental energy source of all ecosystems is the Sun, which sends a large amount of energy to Earth in the form of light and heat.

The various green plants use energy from the sun, water and nutrients from the soil, and carbon dioxide from the air to produce organic matter.

The process by which light is used as an energy source to transform CO2 into organic compounds essential for life is called photosynthesis.

The manufactured organic matter is used by the photosynthetic organisms themselves for the maintenance of their vital processes through cellular respiration.

Energy, once solar energy is transformed by producers into chemical energy by making organic matter in photosynthesis, is transmitted along with matter.

In each transfer of energy, between the different types of organisms there is a release of energy to the environment, in the form of heat.

On the contrary, matter flows cyclically, chemical elements are transferred between living beings and in the physical environment of each ecosystem.

Therefore, we can conclude that the role of photosynthesis in the cycling of matter and the flow of energy through the ecosystem is to produce the transformation not only of inorganic into organic matter, but also of light energy into chemical binding energy, oxygen is released as a waste product and is used by most organisms for cellular respiration.

Use hydrogen bonding to explain how the unique properties of water you observed emerge.

Answers

Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.

Due to the existence of hydrogen bonding between the hydrogen atom and an oxygen atom of a water molecule, it shows the following unique properties.

It is polar in nature.It has a high heat of vaporization and high specific heat.Its solid form is less dense as compared to its liquid form.It illustrates other properties like cohesion and adhesion.It acts as a universal solvent.

How the charges are distributed in a water molecule?

The distribution of charge is determined by the fact that the oxygen atom attracts electrons a bit more strongly than the hydrogen atom. This is due to the unequal sharing of electrons between the two different atoms.

This unequal sharing of electrons is responsible for obtaining a slight negative charge near the oxygen atom, while a slight positive charge near the hydrogen atom.

Therefore, it is well described above.
