Energy is always transferred from [(autotrophs to heterotrophs) (heterotrophs to autotrophs)]. 3. An ecological efficiency of 10% in a marine ecosystem means that [(10%) (80%) (90%)] of the energy consumed at onetrophic level is not passed on to the next higher trophic level.
In-Toeing (Pigeon Toes) Babies may have a natural turning in of the legs at about 8 to 15 months of age, when they begin standing. As they get older, parents may notice their children walking with feet turn inward, also called in-toeing, or walking pigeon-toed. Intoeing can have a few different causes that are normal variations in the way the legs and feet line up.
Hallux varus is a condition in which the big toe points inward, away from the other toes on the foot. The deformity can be caused by a congenital defect, an injury to the foot, or as a complication of bunion surgery. A person who has hallux varus is likely to have trouble walking and wearing shoes, tenderness, and slight swelling.
