One organism benefits and the other is harmed. Commensalism B. Paratism C. D Mutualism Limiting Factory

## Step 1
The problem is asking us to identify the type of symbiotic relationship where one organism benefits and the other is harmed.

## Step 2
Let's analyze each option:
- Commensalism is a type of symbiotic relationship where one organism benefits and the other is neither helped nor harmed. This does not match the description given in the problem.
- Parasitism is a type of symbiotic relationship where one organism benefits at the expense of the other, causing harm to the host organism. This matches the description given in the problem.
- Mutualism is a type of symbiotic relationship where both organisms benefit from the relationship. This does not match the description given in the problem.
- Limiting Factor is not a type of symbiotic relationship. It refers to any factor that limits the growth, abundance, or distribution of a population of organisms in an ecosystem.
