The answer is 50 kcal by the formula of 10% - 500kcal x .1 = 50 kcal it is the approximately chemical energy that can contain by the secondary consumers.
1%- 500,000 kcal x .01 = 5,000 kcal for producers.
10%- 5,000 kcal x .1 = 500 kcal for primary consumers.
10%- 500 kcal x .1 = 50 kcal for secondary consumers.
10%- 50 kcal x .1 = 5 kcal for tertiary consumers.
Each trophic level receives less and less energy, so fewer organisms can be supported at higher levels.
10% of energy gets passed to next level in form of chemical bonds and 1 decimal place.
Answer:
Atoms are composed of extremely small particles that are too small to be seen with an optical microscope.
Size at the atomic level is measured on the nanoscale.
Atoms are made of three subatomic particles - protons, neutrons, and electrons.
Protons:
- positively charge
- located in the nucleus
Neutrons:
- no charge (neutraly charge)
- located in the nucleus
Electrons:
- negatively charged
- located around the nucleus
Atomic number (Z) = the number of protons in the nucleus of an atom.
(i apologize, i don't understand the last part...)
Answer:
Metals are thermal conductor.
A mixture can be separated. Everything in a mixture keeps it's own properties and are not chemically joined together. I am not completely sure about the compound. Although with the cake example, the ingredients have been mixed and kind of "fused" together upon baking. Hope this helps a little. (P.S. trail mix is a good example of a mixture.)
