Which of the following is not true about the mean length of utterance (mlu)? a. the mlu tracks the complexity of syntax usage. b. the mlu is measured in morphemes. c. the mlu refers to the length of spoken statements. d. the mlu increases as children mature.

The correct answer is option A, The MLU tracks the complexity of syntax usage.

Mean length of utterance (MLU) and Mean length of five longest utternaces(MLUL) are two measures used to determine the mosphology and syntax in a child's morphosyntactic development.  MLUL represents the general level of morphosyntactic development and thus is unable to measure the complexity with in one language or the multiple languages.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
