Answer:

Metabolism

Explanation:

The energy flow in food webs and chains begins at the producers and goes to the decomposers, who turn organic into inorganic matter, which will be reused by the producers.

Throughout them, only 10% of the energy is passed from one trophic level to another, as some is lost in the form of heat, and is largely used for vital metabolic functions or the reproduction of living things.

For these reasons, as energy moves from one organism to another, more food will be needed to meet the energy needs of consumers.

What are “cones” in the eye and what do they do?
dusya [7]

Answer:

Cone cells, or cones, are photoreceptor cells in the retinas of vertebrate eyes (e.g. the human eye). They respond differently to light of different or color vision and function best in relatively bright light, as opposed to rod cells, which work better in dim light. Cones are mostly in the center of your retina. They help you see color and fine detail.

Who discovered that dna was the genetic material or transforming factor that could convert nonvirulent r-type streptococcus pneu
KatRina [158]
Discovery
               In 1928 it was discovered by Frederick Griffith in an experiment generally known as transformation.

Experiment
                 
 In his experiment he considered two strains of <em>streptococus pneumonia,</em> one was R-type which was non-virulent and cause no disease in mice, other was virulent and S-type which cause disease and at last death of mice.
This experiment was comprised of four steps which are as follow:

 Step 1:
           First he injected living strain of S into mice, after sometime mouce died.

Step 2:
          He injected living strain of R into mice, the mice alive as he did not got any disease.

Step 3:
         He injected heat killed strain of S into mice and mice remain alive.

Step 4:
           He mixed living R strain with heat killed S strain and then inject into mice. As a result the mice died.

Conclusion:
                  It was found that genetic material from heat killed S stain were transferred to living R (non-virulent) strain, as a result R become virulent and cause the death of mice.
