Question

name:
meerkats (suricata suricatta) are mammals that typically live in groups of 2 to 30 individuals. some group members, called helpers, help parents care for their pups. figure 1 shows how the percent contribution to babysitting and to pupfeeding by helpers varied with the age of the helpers, as categorized in table 1.
a helpers food intake, as measured by daily weight gain (average number of grams gained by a helper per hour during a 24 hr day), can affect its contribution to pup care. figure 2 shows how the percent contribution to babysitting and to pupfeeding by helpers older than 1 yr varied with daily weight gain.

1. according to table 1 and figure 1, across the 4 age categories, as the age of the helpers increased, the percent contribution to pupfeeding:

a. increased only
b. decreased only
c. increased, then decreased
d. decreased, then increased
support with evidence:

Explanation:

Step1: Analyze the pup - feeding graph in Figure 1

• Look at the values for each age category:
• Juveniles: around 6%
• Subadults: around 11%
• Yearlings: around 14%
• Adults: around 11%

Step2: Determine the trend

• From juvenile to yearling (increase), from yearling to adult (decrease)

Answer:

C. Increased, then decreased
