In lakes and ponds there is a whole ecosystem, with its animals and plants. Between them they are in charge of maintaining the entire habitat in favorable conditions for living. The fish tank does not have that cleaning system.
Everything on earth is made up of a fundamental particles that is impossible to see with the naked eye this particle is called the atom. There a over a 100 atoms or more in science. At the center of the atom is the nucleus which contains protons and neutrons. Electrons can be found moving around the orbitals or energy levels , while most of the area outside the nucleus is empty space .
Most of the mass of an atom is concentrated at the center of the nucleus.
Atoms are made up of three subatomic particles called
1. Protons
2. Neurons
3. Electrons
protons - has positively charge particles with a charge
of +1
Neutrons- has no charge it is neutral, 0 charge.
Electrons- has a negative charge particles with an charge of -1.
Relative mass of a particle is the mass compared to the mass of a proton
Relative charge of a particle is the charge compared to the charge on a proton.
Wow this is phrased rather difficult.
My answer would definitely would probably be "C".
Remember that the 10% rule only applies towards energy. Since energy is no indication of healthiness all trophic levels are healthy in their own way.
