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.
Excessive Pronation. Excessive Pronation. Normally when you walk, your foot lands on the outer side of the heel first. Your weight then passes along the inner edge of the sole (normal pronation) and then back to the outside of the foot. In excessive pronation, the body weight stays on the inner edge of the sole.
