The picture below shows the caterpillar of cinnabar moth. The ragwort plants on which the caterpillars feed contain alkaloid poisons. As they eat the leaves, the caterpillars store the poison and this is passed from caterpillar to pupa and finally to the imago/adult. The caterpillars have alternating orange and black bands down their bodies which are highly visible to other organisms. This type of adaptation is called as:
| 1. | Cryptic colouration | 2. | Aposematic colouration |
| 3. | Batesian mimicry | 4. | Mullerian mimicry |

Cornell studied two barnacles – Chthamalus and Balanus. Chthamalus is usually found higher on the rocks. He removed Balanus from the rocks at several sites.
The result showed that Chthamalus spread into the region formerly occupied by Balanus.
The correct conclusion will be:
The result showed that Chthamalus spread into the region formerly occupied by Balanus.
The correct conclusion will be:
| 1. | Interspecific competition makes the realized niche of Chthamalus much larger than its fundamental niche. |
| 2. | Interspecific competition makes the realized niche of Chthamalus much smaller than its fundamental niche. |
| 3. | Interspecific competition makes the realized niche of Balanus much larger than its fundamental niche. |
| 4. | Interspecific competition makes the realized niche of Balanus much smaller than its fundamental niche. |
