Correct answer: B) They produce most of the food that the ecosystem relies on
Decomposers are the organisms that break down the dead and decayed plants and animals. They also help in the breakdown of waste of other organism.
They are found to be very important for the ecosystem, if they were not present in the ecosystem them plant would not be able to get essential nutrients which are necessary for their growth. Because it the decomposers who help in the recycling of carbon and the nitrogen cycle.
Decomposers break down the dead and decayed material into simpler organic matter into carbon dioxide and nutrients.
Example: bacteria, fungi
Ribosomes are attached to<span> the </span>membrane<span> of the </span>ER, making it “rough<span>.” The RER is also </span>attached to<span> the nuclear envelope that surrounds the nucleus.</span>
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.
