Answer:
Chemical nutrients and energy tend to flow in the same direction for most of an ecosystem. The big difference is that the chemical nutrients are ultimately recycled in the ecosystem while the energy is ultimately lost from the ecosystem to the universe at large. Energy in any ecosystem ultimately comes from the Sun
Explanation:
The end products of electron transport chain are:
Water
Adenosine triphosphate (ATP)
Explanation:
- Most of the free energy released during the oxidation of glucose to CO₂ is retained in the reduced co-enzyme NADH and FADH₂, generated during the kreb's cycle.
- Electron are released from these co-enzymes and are eventually transferred to an oxygen molecule to form water.
- These transfer of electron from co-enzymes to oxygen molecule occurs through a series of protein complexes in the mitochondrial membrane. And the process is termed as Electron Transport Chain.
- The large amount of free energy is released during the oxidation of NADH and FADH₂ is used in the production of ATP
Answer: C. Microevolution is small scale change to the gene pool of a population while macroevolution is larger scale changes that lead to speciation.
Explanation:
Microevolution can be defined as a small change in the gene frequency within a gene pool of the species, these changes will be inherited by the organisms and there will not be any drastic change at the species level. But in case of macroevolution the large scale change occurs at the genetic level, which retain for long. This leads to development of new organisms or results in speciation.
