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.
Most people walk with their toes and feet pointing straight ahead. Some children's feet turn in when they walk. This can be called intoeing or pigeon-toed. There are many reasons why a child may walk with their feet pointing in, but most cases are corrected on their own as the child grows up. This is why there aren't many pigeon-toed adults.
