The answer is that it means that the oxygen would be difficult to carry throughout the body, which happens that ATP would be lacking.  Because to create energy there’s a need for respiration and it requires an oxygen.  Also, other body systems will slow down because anaerobic respiration doesn't create enough ATP for the entire body.
 
        
             
        
        
        
Environments likely to be characterized by the presence of dry scrubs and frequent wildfires are those that lack the presence of rain and suffer high sunlight hours.
When referring to the terrestrial biomes that meet the characteristics described, we can include:
- <u>Temperate grasslands</u>
- <u>Cold deserts</u>
The temperate grassland/cold desert biomes have: 
- cold and dry winters 
- hot, dry summers
- Extended sunlight hours
This biome is very dry, and the harsh weather makes it difficult for plants to grow, leading to their <em>dry scrub</em> characteristic. This biome also experiences frequent wildfires due to the <u>intense sunlight and lack of rain to which it is exposed.</u>
