dangina [55]

b. 10% of energy is transferred from the first to the second trophic level.

Explanation:

In trophic level flow of energy is one way, only a small amount of energy get transferred with the organism. A large amount of energy gets dissipated in life processes like respiration, reproduction and digestion. The energy is also released as waste product. Thus, only ten per-cent of the total energy is present in the organism.

The energy transfer does not depend on the number of trophic levels.

Each trophic level receives the 10% energy from the previous trophic level as when algae is eaten by flagship.

Lisa had 20 grams of water. She poured out 15 grams. Which of the following physical properties of the water changes? (4 points)
Black_prince [1.1K]

Answer:

Volume

Explanation:

The boiling point and density of water never changes, no matter how much you add

So the answer CAN'T be Boiling point or Density

Electrical Conductivity changes <em>only when the number of ions in a solution changes</em>

So it CAN'T be Electrical Conductivity

It has to be VOLUME because volume is the only physical property that changes when you add or take away liquid from a liquidous mixture
