Explanation:I hope it helps . i have breifly explained it .

Oxygen gas is one of the products of photosynthesis.

Which reactant is the source for oxygen gas and how is it released?

A .

Water, released when sunlight splits it into oxygen and hydrogen ions

B .

Glucose, released when glucose is broken down into carbon dioxide gas, oxygen gas and water

C .

Carbon dioxide, released when sunlight splits it into carbon and oxygen gas

D .

Electrons, released when they strike the chloroplasts

Green plants capture energy and convert it into chemical energy by the process known as photosynthesis. During photosynthesis, carbon dioxide and water are transformed into simple carbohydrates and oxygen is liberated into the atmosphere.

light

6CO2 + 12H2O ----------------> C6H12O6 + 6O2

chlorophyll

Water is also used as a source of hydrogen required for reduction of carbon dioxide to form carbohydrate.

Water is oxidised in presence of light and chlorophyll. Hydrogen is removed from water and oxygen is released as follows:

light

4‎H20 ---------------> 2‎H20 + 4H+ + 4e− + O2

chlorophyll

or,

2‎H2O ----------------> 4H+ + 4e− + O2

Hence the source for oxygen gas is water and it is released when water splits in the presence of sunlight into oxygen and hydrogen ions.

So, the correct answer is 'Water, released when sunlight splits it into oxygen and hydrogen ions'.

What does a pyramid of biomass represent? A. Range of food webs found in one trophic level B. Percentage of energy that's passed

Klio2033 [76]

The pyramid of biomass represents a range of food webs found in one trophic level

A pyramid of biomass refers to graphical representation of biomass that is present per unit area of all the various trophic levels of the ecosystem.

<h2>Further Explanation</h2>

The graphical representation shows the relationship between biomass and trophic level that quantify the biomass that is present in each trophic level of energy community at a given period of time.

There are two types of pyramid of biomass, they include

Inverted pyramid of biomass
The upright pyramid of biomass

Inverted pyramid of biomass: a very good example of inverted pyramid can be seen in a case of pond ecosystem, where major producers in the ecosystem (mass of phytoplankton) will be lower than the mass of heterotrophs, such as insects.

The upright pyramid: The first thing on the upright pyramid is the producers, such as plants. The plants are present at the bottom level of the pyramid and followed by consumers.

Within the pyramid, the highest level is occupied by the carnivores; they are the lowest quantified amount of biomass. In upright pyramid the total weight of the producers is far more than when the weights of all the consumers are combined.

However, the main issues with the pyramid of biomass are that every trophic level of the pyramid seems to have more energy than it does.
