Explanation:
To find the number of atoms in each specie, we consider the coefficient and the subscript of each of the given atoms.
1. NaCl:
Na = 1 atom
Cl = 1 atom
2. CO₂
C = 1 atom
O = 2 atom
3. O₂
O = 2 atoms
4. C₆H₁₂O₆
C = 6 atoms
H = 12 atoms
O = 6 atoms
For the second part;
1. 2NaCl
Na = 2 atoms
Cl = 2 atoms
2. 3CO₂
C = 3 atoms
O = 6 atoms
3. 4O₂
O = 8 atoms
4. 2C₆H₁₂O₆
C = 12 atoms
H = 24 atoms
O = 12 atoms
Answer:
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. (Draw a plant and this is tghe one you underline)
A heterotroph is an organism that eats other plants or animals for energy and nutrients. (You can draw a dog, cat, frog or a person)
Nitrogen is special because it is necessary for growth and reproduction. It's needed for plants and animals to survive. The main function for the atmosphere i believe is to give oxygen and nitrogen.
