Question

Observation 2: Some caterpillar species are camouflaged in their appearance. They are generally very difficult to distinguish from their habitat. Additionally, these species are generally solitary. Based on this information, please answer the following questions 1. Generate a measurable hypothesis to explain these observations. 2. Based on your hypothesis generate a prediction about the behavior of insectivorous birds towards caterpillars. 3. Outline an investigation to test your hypothesis in the space below, identifying the dependent and independent variables. Additionally, make sure you address your controls and replicates!

Explanation / Answer

1)

According to the question, there are very few of the caterpillar who can camouflaged in their appearance. And it is cearly mentioned that these species are generally solitary, that means that these species are rare.

While choosing the null hypothesis, we choose that event which is actually happening or more chance of happening or which is true. In this case, in general caterpillars can not camouflage in their appearance. So, here we can form the null hypothesis as,

H0: Caterpillars can not camouflaged in their appearance.

against:

H1: Caterpillar can camouflage in their appearance.

2)

If we consider the above hypothesis, then if the null hypothesis is rejected, that means caterpillars can camouflaged in their appearance, that means insectivorous birds can be fooled by this property of caterpillars and they can survive.

and if the null hypothesis is not rejected, that means our data does not have that much evedence that we accept caterpillars camouflaging their appearance, in this case the insectivorous birds will eat the caterpillars.

3)

Here no avariable is mentioned in the question,

but if one has to suggest the variables,

then the ability to camouflage will be the dependent variable here, with taking only binary values (0,1).

and the independent variable can be, weather, area, food that caterpillar takes, temperature etc.
