Answer: Two hydrogen nuclei come together to produce one helium nucleus and two protons, and energy is released.
Explanation:
All stars (including the Sun) at birth begin to fuse two hydrogen nuclei to form helium through nuclear fusion.
In this sense, nuclear fusion is the union of two light atoms, releasing energy in the process, which is the cause of the great luminosity of a star. Especifically, the hydrogen nuclei will begin to fuse, generating helium nuclei in the process and releasing huge amounts of energy.
To unerstand it better:
To shine, the stars transform their hydrogen into helium by means of nuclear fusion. When at half of its life a star is without hydrogen, the nucleus becomes entirely helium and the star declines, becoming colder and brighter due to the energy generated by the nuclear reactions, then the star begins to contract.
Nevertheless, if the star is bigger, this helium will be also consumed and the nucleus transformed in Carbon, then in Oxigen, and so on. Being the last transformation Iron until the star delivers all its energy.
Answer:
Explanation:
Ecology: It is the discipline of biology. It studies the interaction between the organisms and their interaction with their non-living physical environment. It suggests that what factors influence the distribution and abundance of organisms.
Ecosystem: It is a biotic community in which living beings interact with their non-living physical environment. In other words the ecosystem is a place where living beings (biotic factors) interact with the non-living beings (abiotic factor).
Organism: An organism is an individual which belongs to a particular species or life form. An organism perform functions necessary to survive. It exhibit features of living being. The example of organism includes the plants, animals, fungi, and others.
Population: It is a group of members of the same species which are capable of reproducing and producing viable fertile offsprings. The population may vary in functional and morphological forms.
Community: A community is a group of two or more distinct species. These species interact among themselves so as to survive and performing functional roles in the ecosystem. For example, plants provide food to animals in return the animals disperse the seeds of the animals.
