Moving up trophic levels there is an increase in energy, entropy, and biomass.
a. true
b. false

The given statement is false.

Explanation:

There is loss of energy taking place when one moves up in the trophic level because of the activities like respiration and movement. It is known that approximately 90 percent of the energy is lost in between each of the trophic level. The concentration of energy level at each of the trophic level diminishes as one moves through an ecosystem, about 10 percent of the energy at any of the trophic level is conducted towards the next level, and the remaining of the energy is lost due to certain metabolic procedures.

What is the "Scientific Method"? A method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.

Explanation:

The Scientic Method works, The process of the scientific method involves making conjectures which in other words is a hypothiese , deriving predictions from them as logical consequences, and then carrying out experiments or empirical observations based on those predictions.Scientists then test hypotheses by conducting experiments or studies. Scientists use this method on many experents to collect data easier and to collect measurable, empirical evidence in an experiment related to a "Hypothesis".
