Sunlight is the source of energy because producers such as grass and trees use photosynthesis to make energy from sunlight. Grass and trees are then eaten by animals like cows, chickens, and pigs. The animal takes in the energy it receives from the foliage, and humans in turn, receive energy from eating the livestock.

Answer:
Principles of Geology
Explanation:
J. Henslow gifted Darwin the first volume of Principles of Geology, written by Charles Lyell. The book explains about the old age of the earth. Accordingly, the slow rate of several geological processes suggests that the earth is very old.
Darwin read the book as the ship was crossing the Atlantic and learned about geological processes occurring over the millions of years. For example, he learned that the earth's surface was not formed by some catastrophic event.
In his book, Lyell explained the slow and gradual geological processes like erosion gave rise to the vast landscapes present on the earth's surface.
Darwin compared the time taken by geological processes to form the earth's surface and reasoned if these millions of years were enough to support the evolution of species.
The answer is do all of these organisms use chemosynthesis.
Chemosynthesis is a process in which some bacteria produce sugar, similarly to photosynthetic process. But, while in photosynthesis the energy of Sunlight is used to convert carbon dioxide and water into sugar and oxygen, in chemosynthesis, carbon dioxide, oxygen, and hydrogen sulfide are used to produce sugar, along to water and sulfur. This process is preferable when there is no light and the environment is rich in sulfide or methane, such in deep sea vents.
Thus, to asses the variety of organisms found around deep sea vents, it should be researched if all organisms use chemosynthesis, or maybe some other process.
