The primary role of the respiratory system in living organisms is B. TO OBTAIN OXYGEN.

Through the process of breathing, we inhale oxygen and exhale carbon dioxide. Oxygen is then transported by our blood to be distributed to the various parts of our body in order for these parts to function properly.

The absence of oxygen in the body will result to the gradual decline and death of our cells. When our respiratory system is compromised, it affects how our brain and heart function and may cause lasting damage if not quickly resolved.

Does anyone know what this is asking :)? And give an example of what I am supposed to put? BRAINLIEST
My name is Ann [436]

Answer:

Kinda Baboon

Dugong

Mara

Jaguarundi

Mountain Tapir

Red Wolf

Explanation:

You have to remember that phylogenic involves how a species is diverse or a specific feature of that species so the last two boxes are asking what features of this animal makes it unexpected or difficult to know for it's opponent. A quick example on the first fight, a baboon can climb and get to high places meaning the fruit bat is going to have a hard time getting away from it.

Hope this helps.
