Final answer:
The correct answer is a terrarium, which is an enclosed glass container used for keeping plants and small land animals, including turtles and lizards.
Step-by-step explanation:
The enclosed glass container used to keep plants and small animals, such as turtles and lizards, is a terrarium. An aquarium is primarily used for fish and aquatic life, while a vivarium is a general term that could include any small animal or plant enclosure used for observation or research. Lastly, a herbarium is a collection of preserved plant specimens and associated data, used for scientific study. When considering experimental setups similar to these enclosures, a scientist setting up environments for species interaction observation, such as analyzing the egg laying behavior of female frogs in the presence or absence of predator fish, would be creating a mesocosm, which is a controlled outdoor environment that mimics natural conditions.
