The three types of symbiotic relationships are commensalism, mutualism, and parasitism.
Commensalism: One organism benefits from the symbiotic relationship while the other remains unaffected. Example: Barnacles and whales.
Mutualism: Both organisms benefit in the symbiotic relationship. Example: Humans and the bacteria in their digestive tract.
Parasitism: One organism in the symbiotic relationship benefits at the other organism's expense. Example: Fleas and dogs.
Interaction between species is called parasitism, as option D shows.
<h3>What is parasitism?</h3>
- It is a disharmonious relationship between two living beings.
- It is a relationship where only one of the individuals benefits while the other suffers harm.
A parasite is a living being that takes advantage of another living being's resources, stealing them completely. An example of this is the strangler fig which uses the structure of another plant to get sunlight and nutrients.
The strangler fig does not supply the host plant with anything, but absorbs its nutrients and prevents it from receiving sunlight, causing it to slowly die.
In this case, we can see a clear example of parasitism.

The second skater accelerates at 6
to the right.
- Let the first skater be F.
- Let the second skater be S.
<u>Given the following data:</u>
- Acceleration of F = 3

To find the acceleration of the second ice skater, we would apply Newton's Second Law of Motion:
Mathematically, Newton's Second Law of Motion is given by this formula;
× 
Substituting the given values, we have;
× 
<em>Force </em><em>= </em><em>300 Newton</em>
<u>Note:</u> The same force is acting on the two ice skaters and the second ice skater would be pushed in the opposite direction (right).
Now, we would find the acceleration of the second ice skater:

<em>Acceleration of S </em><em>=</em><em> 6 </em>
<em />
Therefore, the acceleration of the second ice skater is 6
to the right.
