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.

The ultimate souce of energy for the food chain is solar energy from the sun. It allows plants to convert the solar energy to chemical energy for growth. The growing plants in turn allow heterotropic animals to consume them to obtain energy of their own.
Answer: elastic fibers
Explanation:
Elastic fibres are the essential durable component present in mammalian connective tissueand functions to provide proper pulmonary, cardiovascular and intestinal system structure and function. Their structural function is to provide elastic recoil and resilience for the tissues.
Elastin fibers ahve two main including microfibrils and elastin containing fibrillin play a mechanical and structural role in the arteries, and their important function is to provide the tissues with resilience and elasticity.
Hence, elastic fibers helps arteries to adapt to changes in blood pressures that accompany the heartbeat.
