Commensalism is a situation in nature where there is an association between two organisms that benefits one but does not help nor harm the other.
Let's go through each example in order to find one with commensalism.
A). Honey bees that feed on the pollen of cornflowers and help the flowers reproduce.
This is not a form of commensalism as both organisms mutually benefit from the association.
B). Barnacles ride on a gray whale's back to obtain food, and the whale is not harmed.
This is a form of commensalism. The barnacles benefit from riding on the whale's back as they obtain food. The whale is also unharmed in the process.
C). Squirrels and chipmunks eat the same nuts in a forest where food is scarce.
This is not a form of commensalism as neither organism benefits. There is an increased competition for food that harms both of the organisms.
D). Prairie dogs often collect and eat food in groups so they are better protected from enemies.
This is not a form of commensalism as the interaction of the organisms is within the same species. In order for commensalism to take place, two different species must interact.
The best example of commensalism is B.
The prevailing theory is that sexual reproduction, which requires two genders, allows genetic intermingling that overall is very good for both the individuals and the species as a whole. Asexual reproduction, on the other hand, is largely static, where each offspring is genetically identical to every other.
The answer is mean!
mean is the average of a group of numbers; therefore, it is the most efficient and accurate!
Hope this helps!! :)
Answer:
Step 1
The plant takes in carbon dioxide in the atmosphere through the stomata on its leaves. It is worth noting that there are some stomata on the stems as well.
Step 2
Water gets into the plant mainly through the roots and finds its way to the leaves, where photosynthesis occurs. Plant roots are specially designed to draw water from the ground and transport it to the plant leaves through the stem.
Step 3
Chlorophyll, the green coloring matter of the leaf, traps the energy from sunlight as it shines on the leaf. It is worth noting that it is chlorophyll that gives the leaf its green color.
Step 4
The solar energy is used to break water down into hydrogen and oxygen. Then hydrogen is combined with carbon dioxide to make sugar, which is food for the plant. Oxygen is released as a byproduct through the stomata.
Chemical reactions occur with the help of protons from the water molecules and electrons from the chlorophyll molecules to produce Adenosine Triphosphate (ATP). ATP provides energy for cellular reactions and Nicotinamide Adenine Dinucleotide Diphosphate (NADP), which is integral in plant metabolism.
