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.
1. Know the Difference Between Pronation and Supination. Both pronation and supination are issues signified by the way your foot hits the ground as you are running or walking. But while pronation involves and inward roll of your foot and ankle, supination is the outward rolling of your foot and ankle. In a pronated foot, the inside part of your foot and the arch absorb most of your weight as you land. A supinated foot, on the other hand, means that the outer edge (pinky-toe side) bears the majority of your weight. Neither foot position is healthy for your feet or ankles, as both can cause serious pain and injuries.
