Question

A scientist is studying an aquarium ecosystem that contains water, plants, and fish that eat those plants. The aquarium has glass walls so light can get in, but it is sealed so no material can move into or out of the tank. When the scientist turned the aquarium's light on, carbon in the water started decreasing. How is carbon moving and what is happening to the amount of carbon in the living things inside the aquarium? Explain your thinking as completely as possible.

Answer 1

Answer:

Carbon moves from the plant to the fish when it feeds on them. Carbon in form of carbondioxide is used by plants during photosynthesis.

The amount of carbon is decreasing due to the photosynthetic action of the plants in the aquarium

Explanation:

According to this question, the aquarium contains water, plants and fish. The glass of the aquarium is transparent and allows the passage of light. Plants are unique set of organisms that have the ability to produce their own food (organic molecule) using the energy from light which they absorb via the Chlorophyll pigment in their Chloroplast. This process carried out by plants is called PHOTOSYNTHESIS.

Carbondioxide, which is a compound of carbon, is an important component needed for photosynthesis. It is released when living organisms undergo respiration. The released CO2 is then absorbed by plants to produce their food (glucose) during photosynthesis. The fish in the aquarium is an heterotroph that relies on the plants for its carbon source. It feeds on the plants to get carbon compounds. Therefore, carbon moves from the plants to the fish in the aquarium.

The amount of carbon in form of carbondioxide (CO2) decreases when the light was switched on in the aquarium due to the process of photosynthesis carried out by the plants.

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

Answer 2

It feeds on the plants to urge carbon compounds.

• Therefore, carbon moves from the plants to the fish within the fish tank.

• the quantity of carbon in kind of carbondioxide (CO2) decreases once the sunshine was switched on within the fish tank because of the method of chemical change administered by the plants.

• During the daytime, once chemical change takes place, the plant releases O (O2), that is employed by the fish and different creatures in your fish tank.

• At night, once no lightweight is obtainable, the plant respires in reverse, manufacturing carbonic acid gas and mistreatment O

• In a perfect gas exchange cycle between plants and fish within the fish tank, the fish draw O contained in water, remodel it and unharness greenhouse emission (CO2).

• Then, plants below the influence of sunshine (in the method of photosynthesis) absorb this greenhouse emission and convert it into pure O (O2).

• In the water aquariums plants use carbonic acid gas to grow throughout the day throughout a method known as chemical change.

• the method of chemical change in plants additionally needs lightweight, carbonic acid gas and water.
