Does this planet have an atmosphere? How can you tell?

Large creatures can fly through the air. What does this tell us about the density of the air?

 

  
 

We also see trees and vegetation similar to that on Earth. What can you say about the composition of the atmosphere?
Is this planet near a star?
Assuming the colour of the vegetation is due to the presence of chlorophyl what does this indicate about the planet's ecosystems?

What types of creatures suggest that a complex ecosystem exists on the planet?
 
 
Large creatures such as the one pictured on the right are shown to exist. Where abouts are these creatures in the food chain? Explain.
 
 

We are shown huge creatures, in what appears to be cold conditions. These creatures are slow moving and have, what appears to be heavy,large structures on their feet. Suggest reasons why.

What does this say about the planet?
