Heterotrophic, non motile, and multicellular organization. Not prokaryotic. If this helps, let me know!
4. They need to be able to sustain themselves using low amounts of water. Also depending on the animal it might be good for them to have less fur, be light colored, or be a similar color to the soil/sand.
Aerobic respiration is the process by which cells produce energy with the use of oxygen. In this analysis, we could suggest that compared to those organisms that are 1000m deep, those that are on the surface can produce energy more efficiently. Hence, they can greatly reproduce doubling their size within a small period of time.
The adaptation that best fit for those that are in 1000m deep is anaerobic respiration.
Producers! they are plants that all the animals feed off of, hence creating a food web/chain.
