Plants serve as the main source of nutrition for humans as well as provide many products for human use, such as firewood, timber, fibers, medicines, dyes, oils, and rubber.
Plants are multicellular eukaryotic organisms whose mode of nutrition is mainly autotrophic.
Plants play many important roles in life more especially that of producing food on which many other organisms depend on.
Some of the important ways by which plants support human life include:
- Provision of food: plants trap the energy of the sunlight and through the process of photosynthesis produce food on which other living organisms such as animals depend on.
- Provision of oxygen: during the process of photosynthesis, plant release oxygen into the atmosphere which is needed by animals for respiration.
- Recycling of water: through the process of transpiration occurring in leaves of plants, water is recycled in nature.
- Provision of other products such as timber, fibers, medicines, dyes, oils, and rubber.
Therefore, plants serve as the main source of nutrition for humans as well as provide many products for human use, such as timber, fibers, medicines, dyes, oils, and rubber.

When the balanced equation for this reaction is:
2SO3 → 2SO2 + O2 so, by using ICE table:
initial 0.391 0 0.125m
change -X +2X +X
Equ (0.391-X) 2X 0.125+X
when Keq = concentration of products / concentration of reactants
so, by substitution
4.34 = [2X]^2 * [0.125+X] / [0.391-X]^2 by solving for X
∴ X = 0.357 m
∴ the concentration of SO2 = 2x = 2 * 0.357
= 0.714 m
Answer:
The binding energy present in the atomic nucleus that holds the protons and the neutrons together and its magnitude is one million times stronger than the electron binding energy in small atoms
Explanation:
The minimum required force to dismember an atomic nucleus into its constituent components, of protons and nucleus (collectively called nucleons) in known as the nuclear binding energy.
Energy is required in separating the nucleons hence the binding energy of a nucleus is always positive
According to Einstein's Energy and light relation E = mc², when a nucleus is formed from the number of free protons and neutrons, the sum of their individual masses is more than the mass of the formed atomic nucleus. The mass deficit of the neutron, also known as the 'missing mass' or mass defect indicates the amount of energy released in forming of the nucleus which therefore has different characteristics from its constituents as mentioned above
The amount of mass that is equivalent to the binding energy of the nucleus as shown in the Einstein's equation (E=mc²) is represented by the missing mass or mass defect of the formed nucleus or the difference in mass between the nuclear mass and that of the sum of the individual masses of its constituent protons and neutrons
