Answer:
Air,water,land,these are the A-biotic factors of the environment and are associated with life in many ways and life is totally defendant on these A-biotic factors of the life
Explanation:
Life is basically dependent on two components the biotic (living things) and A-biotic (non living) components of life.Living component are inked to each other with food chain and the energy is transferred between the food chains and the energy is made by the producer with the help of a biotic factors associated with the life. By using A-boitic component the producers the primary component of the food chain make the food and is consumed by the consumers and then the same way the energy is transferred from on level to the next level and energy is consumed up to 10 percent in each level of the food chain.

<u>Evolution is sometimes a controversial:</u>
Evolution is the most scientific explanation about how the life forms of earth originated and turned into the form that we see today.
I don’t think there should be a controversy because there is no other explanation that proves to be more logical than the theory of evolution. Evolution is a theory that has several supporting proofs and the theory itself was formed after several years of detailed study and observation.
I don’t think alternatives to evolution should be taught at schools. Alternative theories to evolution are based on various religious beliefs which lack a scientific basis.
Schools should be a place that enables students to do productive scientific thinking and teaching alternatives to evolution wouldn’t be a good idea.
