Large mammals, such as Roosevelt elk, black-tail deer, black bear, and coyote, use grasslands as foraging areas and/or travel routes to adjacent lands. Smaller mammals, such as voles and mice, thrive in grasslands. These smaller mammals serve as prey for raptors such as red-tailed hawks, northern harriers, American kestrels, and various species of owls, all of which use open grasslands as hunting grounds. Songbird and shorebird species use grasslands to rest, nest and feed.
Vitamins D, E and the Bs. The B vitamins support energy production and protein metabolism, both of which are key to muscle building. You usually get enough B vitamins through your diet, but vitamin B-12 may be lacking in vegans and vegetarians, so check with your doctor to see if you might need a supplement.
Red blood cell formation also depends on B vitamins. Thiamin, niacin, riboflavin and pantothenic acid are among the B vitamins that your body loses during each workout. The B vitamins work closely together so rather than singling one out, you should take a B vitamin complex. A B-complex contains multiple B vitamins, to support your work out, particularly if your diet does not include natural sources of B vitamins, such as animal proteins, leafy green vegetables, beans and peas.
