Answer: Carbon dioxide and also bring in more oxygen for supporting the aerobic metabolism
Explanation:
The aerobic metabolism is one of the type of process in which the body basically helps in creating the energy in our body by the process of combustion of the fats and carbohydrates in the oxygen presence.
According to the given scenario, when we doing exercise the breath become more faster and at that specific time it is very important to expel the carbon dioxide and then inhale more oxygen for supporting the aerobic metabolism in the our body system.
Therefore, The given answer is correct.
Answer:
drinking water after a long run
Explanation:
When there arises a change or shift in the state or action of any organism because of any external stimulus, the result is said to be the response to external stimulus. The response or reaction to the external stimulus arises when the organism experiences or senses the stimulus.
Drinking water after a long run is an example of the response to external stimulus. Here, the external stimulus is the loss of water in the water because of the action of running. This makes the individual drink water which is a response to the external stimulus.

Ecosystems maintain themselves by cycling energy and nutrients obtained from external sources. At the first trophic level<span>, </span>primary producers<span> (plants, algae, and some bacteria) use solar energy to produce organic plant material through photosynthesis. Herbivores—animals that feed solely on plants—make up the second trophic level. Predators that eat herbivores comprise the third trophic level; if larger predators are present, they represent still higher trophic levels. Organisms that feed at several trophic levels (for example, grizzly bears that eat berries and salmon) are classified at the highest of the trophic levels at which they feed. Decomposers, which include bacteria, fungi, molds, worms, and insects, break down wastes and dead organisms and return nutrients to the soil
