Answer:
Because they lose most of the energy as heat when they perform metabolic activities
Explanation:
Cells of all living organisms require energy in form of ATP to perform their cellular functions. In an ecosystem, organisms obtain this energy by feeding on one another. However, these energy transfer starts from organisms capable of using sunlight called PRODUCERS e.g plants.
Herbivores, which are PRIMARY CONSUMERS get their energy by feeding on these plants. However, according to the PYRAMID OF ENERGY, which represents the flow of energy in an ecosystem, only a few portion of the energy (about 10%) derived by plants from the sun gets transferred to herbivores. This is because most of the energy (about 90%) is lost as heat when the plants undergo metabolic activities.
Answer:
Stephen is not his biological father.
Explanation:
DNA fingerprinting is a technique use to determine the DNA sequence of an individual organism. Short tandem repeats are unique among the individuals ans used to identify the individual in population.
The George DNA fingerprinting shows that he has STRs length of 6 and 7. Stephen's STRs does not match with his son George whereas Mary shows some similarities with George STRs. This indicates that Stephen is not the biological father of George because the biological father's STRs must match with the children STRs.
Thus, the correct answer is option (a).
The one that is being described above is MY PLATE. My Plate is actually established by the <span>USDA Center for Nutrition Policy and Promotion. This literally looks like a plate and is divided with the necessary food intake that the person should have which includes the five main groups. It is easy to follow most especially for parents who wanted to ensure and serve healthy meals for their children.</span>
