the grass, acorns, and mushrooms should have the most abundant populations because they are on the bottom. the problem also states that this is a healthy ecosystem meaning that they should have the highest population because they supply energy for the next trophic level, which then the energy continues trvaling up to the next trophic level.

Answer:

a) Producers: grass, acorns

Primary consumers: squirrel, mouse, deer

Secondary consumers: coyote, cougar

Decomposers: mushrooms ( not a part of producers )

b) The organisms in first trophic level i.e. grass and acorns are going to have the highest population. They need to supply energy to the subsequent trophic levels. Since their biomass is less on individual level, their number needs to be high to be able to transfer enough energy to the next trophic level where the organisms have higher biomass.

Answer: Oxygen

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'.
