The amount of total energy at each trophic level decreases as it moves through, so 90% is lost at each level. This means that only 10 percent of the energy at any trophic level is transferred to the next level; and the rest is lost as heat.
In this case, if a plant ecosystem has 3000000 kilocalories (kcal) of energy, about 300000 kcal will be transferred to primary consumers (for example grass hoppers). If the red-tailed hawks are tertiary consumers, they will get 3000 kcal of energy.
Answer:
Energy conversion, also termed as energy transformation, is the process of changing one form of energy into another. Energy conversion occurs everywhere and every minute of the day. There are numerous forms of energy like thermal energy, electrical energy, nuclear energy, electromagnetic energy, mechanical energy, chemical energy, sound energy, etc. On the other hand, the term Energy Transformation is used when energy changes forms from one form to another. Whether the energy is transferred or transformed, the total amount of energy doesn’t change and this is known as the Law of Conservation of Energy.
<h3><u>Answer</u>;</h3>
D. reproduce and increase the frequency of their genes in the population
<h3><u>Explanation;</u></h3>
- Natural selection refers to the process that occurs naturally by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment.
- <em><u>For example, a prey population consists of individuals with a variety of running speeds, will be better adapted to the environment as they will be able to run away from their predators and hence reproduce and increase the frequency of their genes in the population.</u></em>
