Explanation:
Large animals have a specialized organs for exhalation and inhalation of gases due to the requirement of large amount of oxygen for cellular respiration. Respiration is a process in which energy is released in the form of Adenine tri phosphate (ATP) in the mitochondria of the cell with the addition of oxygen. The waste product such as carbondioxide is produced which is removed from the body body through lungs.

Bacteria provides vitamins to humans
Explanation:
The correct answer would be that bacteria provides vitamins to humans.
<u>By definition, mutualism is a type of symbiotic relationship between two organisms in which both benefit from each other.</u>
Bacteria in the gut of humans that provides vitamins to humans also benefit by making the human gut their shelter. While the vitamins represent an important nutrient to humans for their proper functioning, the shelter is also necessary for the bacteria for their safety.
<em>Hence, the observation that bacteria provide vitamins to humans is consistent with the argument of researchers that some bacteria found in the human gut are in a mutually beneficial relationship with humans.</em>
The greenhouse effect is the trapping of a stars warmth in the lower atmosphere of a planet by gasses in the air trapping the energy. This is similar to what actual greenhouses do, where they trap the warmth and humidity of the air inside it so plants can flourish. Farm animals produce a huge amount of the greenhouse gasses required for our planet to trap the suns warmth.
