The correct Answer is:
To identify the types of interactions from the given table, we need to analyze the signs assigned to each interaction: 1. **Interaction (i)**: The table shows a '-' sign for both species A and species B. This indicates that both species are negatively impacted by their interaction. This type of interaction is known as **competition**, where both species compete for limited resources, leading to a detrimental effect on both. 2. **Interaction (ii)**: The table shows a '+' sign for one species and a '-' sign for the other. This indicates that one species benefits while the other is harmed. This type of interaction is known as **parasitism**, where the parasite benefits at the expense of the host. 3. **Interaction (iii)**: The table shows a '+' sign for one species and a '0' sign for the other. This indicates that one species benefits while the other is neither helped nor harmed. This type of interaction is known as **commensalism**, where one species benefits and the other is unaffected. Based on this analysis, we can summarize the interactions as follows: - (i) Competition - (ii) Parasitism - (iii) Commensalism Thus, the correct option is **D**, as it accurately describes the types of interactions identified.
