Not a lot besides the fact that they are both mixtures in water, because a solution is a mixture in which the solutes ( solids) dissolve, and suspension is a mixture in which the solutes don't dissolve.
Some examples of important nonliving things in an ecosystem are sunlight, temperature, water, air, wind, rocks, and soil. Living things grow, change, produce waste, reproduce, and die.

Yes, they ate the only mammals which could fly because flying squirrels, possums or etc. could only glide for a short distance and time, unlike bats. There are no reptiles who could fly, but there are reptiles who could glide which I think is completely different. But they said that Pterosaur existed which they believed it is a flying reptile dinosaur. Just look it up. :)
Biological Organisms: Living things that are capable of reacting to stimuli, reproduction, growth, and homeostasis. Organisms are classified by taxonomy into specified groups such as the multicellular animals, plants, and fungi; or unicellular microorganisms such as a protists, bacteria, and archaea.
