on flora and fauna.
This can take many forms. Marine life, for example, is influenced by tidal
patterns. Animals tend to be active or inactive depending on the position of the sun or
moon. Numerous creatures, humans included, are largely diurnal – that is, they like to
come out during the hours of sunlight. Nocturnal animals, such as bats and possums,
