I found the exercise on the internet and these were the options:
"-Help
-Pelh
-Elhp
<span>-Pleh"
The letter "p" would be fastest recognised by an English speaker in "Help". Letters are more recognisable when they are in a context that's known. If any of the other words was given to an English speaker to memorise, he would probably memorise the letter by letter, while with "help", he would be able to know straight way what letters were contained in it without having to make a conscious effort to memorise them one by one. Because of this, the letter "p", for an English speaker would be the fastest recognised in the word "help" rather then in other unknown word.</span>
Answer: The correct answer is-
B. by mutating their DNA in response to environmental conditions to gain beneficial traits.
Antibiotic resistance in bacteria means the bacteria is not susceptible to the antibiotic that is the effectiveness of antibiotic against the bacteria is eliminated or reduced.
It occurs when bacteria undergoes mutation that is alteration in the genetic material ( for instance, in one mechanism of resistance, mutation changes the protein that was earlier target for the antibiotic).
Therefore, by mutating the DNA in response to environmental condition ( such as exposure to antibiotic in this condition), bacteria gains beneficial characters and become resistant.
Thus, option B) is the right answer.
In a typical energy pyramid, herbivores have more energy available to them than carnivores, tertiary consumers are fewer than secondary consumers, and soil organisms recycle nutrients.
<h3>Energy pyramid in the ecosystem</h3>
The producer forms the bases of the energy pyramid of any ecosystem. this is followed by the primary consumers, secondary consumers, tertiary consumers, and quaternary consumers respectively.
The population at each trophic level decreases as we move up, resulting in a form of a pyramid. Also, the amount of energy obtained at each trophic level decreases as we move upward.
Thus, one can effectively conclude that:
- Herbivores have more energy available to them than carnivores.
- There are fewer tertiary consumers than secondary consumers.
- Soil organisms recycle nutrients but not energy back into the ecosystem.

Answer:
Energy from the sun light
Explanation:
This happens directly or indirectly.
Producers use this energy directly to make organic material, via photosynthesis, that gets passed down the food chain. Herbivores and other organisms will get this energy indirectly by eating the organic material made by the producers using this light energy.
So all the organisms someway get their energy from the sun light.
