Plants use light energy to produce food molecules during photosynthesis and obtain cellular energy from the bonds of these food molecules during cellular respiration.
The chlorophyll pigment in plants harnesses light energy to ‘manufacture’ glucose/carbohydrates which are later used by the plant for cellular respiration to power cell activities.
Explanation:
The energy from sunlight is used by the chlorophyll pigments to make ATPs through a process called photophosphorylation. In addition, the light energy is used to split water molecules into H⁺ and O²⁻. The H⁺ is then captured by NADP+ which is reduced to NADPH, while O²⁻ is evolved as oxygen. This occurs in the light stage of photosynthesis.
The NADPH is used to reduce carbon dioxide into glucose in the dark stage (Calvin cycle) of photosynthesis. Remember since this is an anabolic process ATPs (the one created through photophosphorylation) are used to power this cycle.
Excess glucose can be converted to starch and stored. Otherwise, the energy captured in the chemical bonds of the glucose are again utilized to make ATPs in cellular respiration.

Explanation:
obviously being a biologist a person would choose to research and perform tasks related to bios I.e something which is living
The answer is that they have traits that enabled them to survive in a changing environment.
During the evolution of the Earth, and later during the evolution of life, the environment was not constant. Change in the environment could lead to an extinction of some species. But, some species were able to adapt or could tolerate a wide range of environmental factors. One of the explanation, why unicellular organisms did not evolve into complex multicellular organisms is because they have traits that help them to tolerate the wide range of factors, and thus, survive in changing environment.
