The answer is Hydrologist
Answer:
Many species would eventually die off because they lack a food source.
Explanation:
<u>Photosynthesis can be defined simply as the biological process of using light to synthesize food (in the form of glucose). It is a process that takes place in plants and involves the synthesis of sugar using inorganic products such as water and carbon dioxide.</u>

The process consists of two stages namely;
- Light reaction
- Light independent reaction.
The products from the light reaction are utilized in the light-independent reaction.
<em>Hence, without light energy, the process of photosynthesis cannot proceed and plants will not be able to manufacture foods. Without foods, many plant species would die off. </em>
Answer;
- radiometric dating of rocks
- fossil evidence
- gradual processes of rock
Explanation;
Radiometric dating confirms that Earth is ancient and explains how extremely slow processes can result in major changes to Earth’s surface. Evidence from radiometric dating indicates that Earth is about 4.54 billion years old. The geology or deep time of Earth's past has been organized into various units according to events which took place.
-The ages of Earth, Moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and the age and duration of a wide variety of other geological events and processes.
