Answer:
c. Protons, electrons
Explanation:
The number of these electrons in a neutral atom is equivalent to the number of protons.
Since protons have positive charge, they balanace the negative charge of electrons. Electrons have same level of charge per particle as a proton.
Neutrons posses no charge, so in a "neutral atom" the number of proton is equal to that of electrons, othermeans it will not be neutral.
When a electron is removed by natural or artificaial means , an ion results which is an electrically charged particle. It also happens some atoms take additonal electrons once they were previously neutral. They can also lose electrons and become positively charged,

Answer:
The freshwater biome is defined as the biome that comprises the water bodies such as lake, pond, rivers and wetlands and where the concentration of salt is almost less than 1%. It occupies near about 20-25% of the total earth's surface.
Generally, the characteristics of the photic zone of a freshwater biome include-
- It forms the upper layer of the freshwater body, ranging from the surface of the water up to a certain depth.
- It is the layer where the sunlight can easily penetrate.
- The photosynthesis process is driven out extensively by the aquatic plants existing in this layer.
- The primary producers are present in this zone that provides the food to almost all the freshwater organisms.
- In this zone, the rate of respiration is equal to the rate of photosynthesis.
