Answer:
Photosynthesis is a process in which energy is produced in the plants with the help of sunlight. In photosynthesis, carbondioxide react with water forming oxygen and food material in the form of glucose. It occurs only in plants.
Respiration is energy releasing process in which energy is released due to the breakdown of glucose molecules with the help of oxygen produces water, carbondioxide and energy in the form of Adenine tri phosphate (ATP). It occurs in all living organisms.

Hope this helps :)
Living systems follow the laws of conservation of mass and energy by <span>stating that </span>matter<span> is not created nor destroyed as a result of chemical reaction.
I REALLY hope this has helped you!!! :)

They play huge role in organisms, every living organism needs proteins.
- enzymatic role ( they build enzymes which lower an activation energy in reactions and increase reaction speed)
- hormonal role (they build hormons)
- structural role (for example keratin)
- transport role ( for example hemoglobin)
- energetic role ( for example aleurone grains in plant cells or they are used to gain energy in human organism when it's out of lipids and carbohydrates)
Answer:
The correct answer is - d. gradualism.
Explanation:
Gradualism is a model of evolution that explains that the smaller variation in an individual organism that is occurring over a period of the time is to the betterment of the organism in their environment.
These changes or variations allow them to thrive and survive with a slow successive change in an evolutionary line or the whole population. It is a consistent process.
Thus, the correct answer is - D. gradualism.
