Answer:
1. Carbon is moving from the living things in the tank into the air when they respirate, and from the air back into plants via photosynthesis
2. The amount of carbon in living things is increasing as plants use the carbon in the atmosphere, and animals eat the plants.
Explanation:
According to the question, a well sealed tank contains air, plants and animals. Since light can get into the tank, plants can perform photosynthesis. Living things in the tank release carbon in form of carbondioxide (CO2) gas through respiration. Plants then make use of this carbondioxide (CO2) to synthesize carbon-containing food (glucose) in the presence of sunlight. This process is called PHOTOSYNTHESIS.
Animals eat those plants and the stored carbon in the plants gets transferred to them. The animals release this carbon into the air again in the form of carbondioxide when they respire. Hence, carbon in the tank moves from the living things (respiration) into the air and back into plants (photosynthesis).
2. Since the amount of carbon in the air is decreasing, the carbon is being used by the living things in the tank. Plants absorb the carbon in the atmosphere for photosynthesis, then animals eat the plants to get the carbon. Therefore, the amount of carbon in the living things is increasing.
1. Carbon is flowing from the living organisms in the tank into the air by the process of respiration and from the surrounding back into plants via photosynthesis.
The animals in the tank utilize the oxygen when they inhale while during exhalation carbon dioxide is liberated. The carbon dioxide in the tank is used by the aquatic plants to produce food and energy in this way the level of oxygen and carbon dioxide is maintained in the tank.2. The quantity of carbon in living, are expanding as plants use this carbon in the process of photosynthesis from the environment and animals consumes those plants.
The deposited carbon in the food gets spent by the animals and they release this carbon back via exhalation. Therefore the quantity of carbon in living things is increasing.To learn more about respiration and photosynthesis follow the link:

Identify the strengths and weaknesses of Mendel’s Law of Independent Assortment.
Answer:
Explanation:
Mendel propel two laws The law of inheritance and that of independent assortment of gene.
Independent assortment of gene explain that alleles of a gene assort independently and that different Allele can show different phenotypic effect and differences. This means that in a gene where we have 2 allele they can both show individual difference where one can have a dominant effect over the other and the other allele is recessive.
This law does not take care of linked gene where alleles don't separate after crossing over sister chromatids but are rather inherited together given rise to complex inheritance.

Archaea
Or
Plants
Or bacteria
Or fungi
Answer:
Archaea bacteria
Explanation:
just search each answer choice asking if its eukaryotic or prokaryotic and it will tell you
Bacteria and Archaea are groups of organisms that are prokaryotic, which means that their cells do not have cellular organelles or a delimited nucleus in the cytoplasm.
The prokaryotic cell is characterized by not having a cell nucleus, therefore its ribosomes are smaller and its genetic material simpler.
Prokaryotes are, in most cases, unicellular microorganisms.
The bacteria is a unicellular and prokaryotic microorganism, which means that it does not have a nucleus, they are a few micrometers long and various shapes including spheres (cocci), rods (bacilli) and helices (spirils).
A diversity of unicellular microorganisms that make up the archaea kingdom lacking nuclei (prokaryotes) is known as archaea.
Their cells are surrounded by a covering (cell wall) made of various materials that give them high resistance against antibiotics or other harmful substances.
Therefore, we can conclude that bacteria and archaea are groups of organisms that are prokaryotic, which do not have a defined nucleus and or organelles surrounded by a membrane.
