A scientist sets up terrarium and a laboratory and observes the growth of lizards in each terrarium, which of the following observations could be used as evidence that the amount of space in an environment can affect an animals growth. Would it be two lizards of the same species grow to different sizes and different size terrarium, or two different species of lizard grow to different sizes in the same terrarium or two lizards of the same species grow to different sizes in the same terrarium or two lizards of the same species grow to different sizes in terrarium with different food supplies.

Two lizards of the same species grow to different sizes in different size terrariums would be the observation that could be used as evidence that the amount of space in an environment can affect an animal's growth. This suggests that the amount of space available to the animal can impact its growth, possibly due to limited resources or stress from overcrowding.
