Show Hint
To identify behavioral responses:
1. Habituation involves reduced responsiveness to repeated stimuli.
2. Sensitisation involves increased responsiveness to repeated stimuli.
3. Imitation and imprinting involve specific forms of learning unrelated to habituation.

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand the behavioral context.
The lizards showed a reduced alarm response over repeated presentations of the predator model. This behavior reflects a decreased reaction to a stimulus after repeated exposure, indicating a form of learning.
Step 2: Analyze the options.
Option (A): Imitation refers to learning by observing and copying the behavior of another individual. This does not apply to the situation described.
Option (B): Imprinting refers to a rapid and irreversible learning process occurring at a specific life stage (e.g., chicks following their mother). This is not relevant to the situation described.
Option (C): Habituation refers to the process of decreased responsiveness to a repeated stimulus over time. This matches the described behavior of the lizards, as they reduce their alarm response after repeated exposure to the predator model.
Option (D): Sensitisation refers to an increased response to a stimulus over repeated exposures. This is the opposite of the described behavior.

- One hypothesis for why the tropics have far greater species richness than higher latitudes is that the tropics are relatively aseasonal. Low seasonality can encourage high species richness through which one or more of the following mechanisms?
- Female \textit{Anopheles mosquitoes bite humans to get blood. Researchers performed an experiment to study whether female mosquitoes use temperature or scent, or both, when locating human hosts. They presented female mosquitoes with membranes kept at different temperatures. Some membranes had human scent applied to them. The response to each treatment was measured as the percentage of females that landed on the membrane (50 females for each treatment). The table shows the treatments and the corresponding responses.}

- You are a plant ecologist studying a plant in the genus \textit{Veronica. You notice that, at open rocky sites, \textit{Veronica} grows as a creeper spreading low to the ground, whereas in grasslands, the stem stands upright. You collect seeds from multiple populations in each habitat type and grow them under uniform conditions in a greenhouse. You find that all the plants grown in the greenhouse have stems that stand upright. Which one or more of the following explanations best support(s) your observations?}
