1. Both objects have mass and therefore have a gravitational force.
2. Lower mass objects have less gravitational force.
3. Higher mass objects have stronger gravitational force.
Explanation:
To solve this problem, we need a recap of the newton's law of universal gravitation:
The law states that "the gravitational force of attraction between two object is directly proportional to the product of their masses and inversely proportional to the square of the distances between them."
F =
}{
}[/tex]
G = universal gravitational constant
m₁ = mass of object 1
m₂ = mass of object 2
r² = distances between the two masses
From this we can infer that, for gravitational force to exists, both objects must have mass.
Since mass is directly proportional the gravitational force, the lower the mass the less the gravitational force and the higher the mass the stronger the gravitational force.

Cause living things can not directly use most of matter which they found in nature. For example carbon, all organism use carbon in complex structure, that is in compound or macromolecule(glucose,fructose,amino acid). we can not directly earn ATP from C which we found in soil/other sources.
