A scientist wants to investigate male-guppy behavior in the presence of female guppies. She puts two long tailed guppies in the same fish tank. The male guppies appear to be indifferent to each other's presence. However, when the scientist added a female guppy to the tank, the male guppies become aggressive toward one another. Throughout the experiment, the scientist gives the fish enough food so that they do not need to compete for it. In the experiment, why does the scientist maintain the abundance of food before and during the presence of the female guppy? (SC.912.N. 1.1)

Question

• The scientist wants to see how the guppies react to various amounts of food
• The scientist wants to see if the female is more interested in food than the male Thaientist wants the guppies to have enough energy to display their natural
O The scientist must ensure that the guppy's behavior is not affected by the need to
compete for food.

Answer 1

The scientist maintains the abundance of food before and during the presence of the female guppy to ensure that the guppies' behavior is not affected by the need to compete for food. By providing enough food for all the fish, the scientist can observe their natural behavior without any external factors influencing their interactions. This allows the scientist to accurately study the male guppies' behavior in response to the presence of a female guppy.

Answer 2

A b c or d

Answer 3

Sorry for the oversight. The correct answer would be:

C) The scientist must ensure that the guppies' behavior is not affected by the need to compete for food.
