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.
Vitamin B Complex. The vitamin B complex consists of eight water soluble vitamins. The B vitamins work together to boost metabolism, enhance the immune system and nervous system, keep the skin and muscles healthy, encourage cell growth and division, and other benefits to your body. Brewer's yeast is one of the best sources of the B vitamins.
