"Three little birds" by Bob Marley
The only thing these three quite different species have in common is that they are all vertebrates.
The same thing that consumers eat, the producers produce, adn the decomposers get rid of. That's the only common thing between the three
Themselves - it's a natural thing all birds do
"Don't worry about a thing, 'Cause every little thing gonna be all right. Singin': "Don't worry about a thing, 'Cause every little thing gonna be all right!" Rise up this mornin', Smiled with the risin' sun, Three little birds Pitch by my doorstep Singin' sweet songs Of melodies pure and true, Sayin', ("This is my message to you-ou-ou:") Singin': "Don't worry 'bout a thing, 'Cause every little thing gonna be all right." Singin': "Don't worry (don't worry) 'bout a thing, 'Cause every little thing gonna be all right!"
The amino acid that is most common in all three animals (humans, dogs, and birds) is glycine. Glycine is the simplest amino acid with a hydrogen atom as its side chain, making it a versatile component of proteins.
Level 9-13 is in "The Big Setup." There are three birds, and all of them are big red birds.
They are all animals. That is about it.
All three are considered animals.
The only thing in common with these three birds is that... ...all are birds. The Moa and the Dodo were both flightless birds, and booth are extinct. The Auk is neither extinct nor is a flightless bird.
Think of it as the same thing as land mammals versus water mammals. Marine mammals first evolved to life on land and then adapted to return to the water, but not all mammals did that. Similar thing with birds. All birds evolved from common flying ancestors, whereas flying mammals evolved from land mammals at a much later point in evolutionary history. Hope that helps.
Common foods that birds eat are: worms, seeds, corn and all of the stuff that is in bird feed.
