Answer:
Primary producers
Explanation:
Phytoplankton belong to the <u><em>primary producers</em></u> trophic level. Beings of the other levels gain energy from phytoplankton. Phytoplankton are also capable of transforming inorganic carbon into protoplasm.
Answer:
An electron will jump to a higher energy level when excited by an external energy gain such as a large heat increase or the presence of an electrical field, or collision with another electron.

The C¬C bond in H₃C¬CF₃ (423 kJ/mol) stronger than that in H₃C¬CH₃ (376 kJ/mol) because of the strong negative inductive effect of fluorine atom
<h3>What is Inductive effect?</h3>
When an electron- withdrawing or an electron- releasing species is allow to introduce to a chain of atoms (generally a carbon chain), according to the species corresponding negative or positive charge is start relayed through the carbon chain by the atoms through which it attached. This makes a permanent dipole to arise in the molecule and is referred to as the inductive effect.
<h3>Types of
Inductive effect</h3>
+ inductive effect
- inductive effect
<h3>What is negative inductive effect?</h3>
Whenever an electronegative atom, like halogen, is introduced to a chain of carbon atoms (generally carbon atoms), this results in unequal sharing of electrons which generates a positive charge which is transmitted through the chain.
This make a permanent dipole to arise in the molecule whereas the electronegative atom get a negative charge and the effect is known as the electron-withdrawing inductive effect, or the -I effect.
Thus, we concluded that the C¬C bond in H₃C¬CF₃ (423 kJ/mol) stronger than that in H₃C¬CH₃ (376 kJ/mol) because of the strong negative inductive effect of fluorine atom.

Answer:
the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object.
