A neuron (also known as nerve cell) is an electrically excitable cell that takes up, processes and transmits information through electrical and chemical signals. It is one of the basic elements of the nervous system. In order that a human being can react to his environment, neurons transport stimuli.
The answer that is not caused by a gravitational pull is two atoms come together to form a molecule because atoms form molecules because of the electrons, and not gravitational pull.
Therefore the correct answer would be,
Two atoms come together to form a molecule.
I hope that this has satisfied you.

Answer: Eating.
Explanation:
Animals obtain energy by eating plants or animals. The only form of energy a cell can use is a molecule called adenosine triphosphate (ATP). Chemical energy is stored in the bonds that hold the molecule together. ADP can be recycled into ATP when more energy becomes available.
The major difference between the flow of matter and of energy is that the flow of matter occurs in a cyclic manner i.e. it is recycled, however, the flow of energy in an ecosystem is unidirectional which means, it is not recycled. The flow of matter follows the following path
1) Decomposers release nutrients when they break down dead organisms
2) The nutrients are taken up by plants through their roots
3) The nutrients pass to primary consumers when they eat the plants
4) The nutrients pass to higher-level consumers when they eat lower-level consumers
5) When living things die, the cycle repeats
In case of flow of energy, the energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life. This loss of usable energy occurs because each energy transfer results in the dissipation of some energy into the environment as heat
