What is true of the energy that is passed from one trophic level to the next in a food chain?

Answers

Answer 1
Answer:

Answer:

The real answer to this question is about 10% of the stored energy of one level becomes stored energy at the next level higher.

Think about it, when a consumer eats the producer it also consumes the energy the producer stored and as the food chain grows the energy is passed through all. The only time the energy is released into heat is when a consumer dies and decomposes, and even then all of the energy isn't released.

Imagine that you are the scientist who discovered cells. If you were to give a speech to a group of fellow scientists, what key points would you include that describe your accomplishments?

Answers

The key points about cell theory are as follows:
1. All living organisms are made up of cells; the organisms may be unicellular or multi cellular.
2. The cell is the basic unit of life.
3. New cells are derived from pre-existing cells.
4. All cells maintain homeostasis.
Some new facts have been added to these basic facts; the new facts added include the following:
(A). Energy flow occur withing all living cells.
(B). Hereditary information derived from DNA is passed from cell to cell.
(C).  All living cells are made up of the same basic chemical compositions.

- cells are basic units of structure and function in living things

- microscope made it possible for people to discover and learn about cells

- all living things are composed of cells

Rob measures the solubility of three different salts in water at 22°C. Which type of graph should he use to display his data?

Answers

The correct answer to this question is a line graph. If Rob needs to create a graph that is able to display the combination of two different values - in this case, level to which the salt has dissolved and time taken - and he needs to have more than one result included, then a line graph is the way to present this.
