Given below is a table depicting population interactions between Species A and Species B.
`{:("Type of interaction","Species A","Species B"),((a),(-),"(+)"),((b),"(+)",(-)):}`
Name the type of interactions (a) and (b) in the above table.
Justify giving three reason, how the type of interaction (b) is important in an ecological context

Explanation

### Step-by-Step Solution:

1. **Identify the Interactions**:
- In the table provided, we have two interactions involving Species A and Species B.
- For interaction (a), Species A has a negative effect on Species B (+) indicates that Species B benefits from the interaction.
- For interaction (b), Species A has a positive effect on Species B (-) indicates that Species A is harmed by the interaction.

2. **Name the Interactions**:
