Short Answer

The brown-headed cowbird does not raise its own offspring. It lays eggs in the nests of other bird species, which then hatch the eggs and raise the young. A scientist investigated whether the growth of a young cowbird is affected by the species of bird that raises it. The scientist’s results for two bird species are shown below.
For each table, draw a graph for the relation given by the ordered pairs $(age,mass)$ . Draw both graphs in the same coordinate plane, and use a different color for each graph.
Compare the graphs from part (a). How is a cowbird’s growth when raised by a red-eyed vireo like its growth when raised by a blue-gray gnatcatcher? How is its growth different?

a. Our required graph would look like:

b. Initially the growth of a cowbird raised by blue-grey gnatcatcher is greater than the growth of a cowbird raised by red-eyed vireo.

a.Step 1. Given Information.

The scientist’s results for two bird species are shown below:

Step 2. Calculation.

We will use red color for data about cowbird raised by red-eyed Vireo and blue color for data about cowbird raised by blue-gray Gnatcatcher.

Upon graphing our given data, we will get our required graph as shown below:

b.Step 1. Given Information.

The scientist’s results for two bird species are shown below:

Step 2. Calculation.

We can see from the graph that for two days the growth of a cowbird raised by blue-grey gnatcatcher is like the growth of a cowbird raised by red-eyed vireo.

After 4 days the growth of a cowbird raised by red-eyed vireo is greater than the growth of a cowbird raised by blue-grey gnatcatcher.
