Select the ones you think are true.
Correct Answer(s)
A. It has a simple vegetation structure.
C. It has a short season of growth and reproduction.
Explanation
The tundra is characterized by a simple vegetation structure, with low-growing plants such as mosses, lichens, and grasses. This is because the harsh climate and frozen soil make it difficult for larger plants to survive. Additionally, the tundra has a short season of growth and reproduction due to the cold temperatures and long winters. During this brief period, plants and animals must quickly take advantage of the available resources to reproduce and store enough energy to survive the rest of the year.

Select the ones you think are true.
Correct Answer(s)
A. Nocturnal animals sleep in burrows during the day in order to stay cool.
B. Some plants store water in their stems.
Explanation
Nocturnal animals sleep in burrows during the day in order to stay cool because burrows provide shade and insulation from the heat of the sun. Some plants store water in their stems as a survival mechanism in arid environments. This allows them to conserve water and withstand periods of drought.
3.
Select the ones you think are true.
Correct Answer(s)
B. Savannas are mostly located near the equator.
D. Because the savanna is so rich in grasses and tree life, many large herbivores live there. Consequently, there are also many powerful predators such as, leopards, wild dogs and lions.
Explanation
Most of the plants don't survive after a fire in the savannas. Overgrazing is beneficial for the savannas.

Comlplete with the name of the proper layer.It has a very limited diversity. _____________
Correct Answer
Rainforest floor
Explanation
The given correct answer for this question is "Rainforest floor". The statement mentions that it has a very limited diversity. This suggests that the layer being referred to is the Rainforest floor. The Rainforest floor is the lowest layer of the rainforest, located on the ground. It is characterized by low light levels, high humidity, and a dense layer of decomposing organic matter. Due to these conditions, the diversity of plant and animal species in this layer is limited compared to the other layers of the rainforest.
8.
Comlplete with the name of the proper layer.Tall trees from this dense layer absorb most of the light energy. _____________
Correct Answer
Canopy layer
Explanation
The given statement suggests that tall trees from a specific layer absorb most of the light energy. This layer is known as the canopy layer. The canopy layer is the uppermost layer of the forest, composed of the crowns of the tallest trees. These trees receive the most sunlight and therefore absorb the majority of the light energy. They create a dense layer that blocks much of the sunlight from reaching the lower layers of the forest.
9.
Comlplete with the name of the proper layer.A few tree species grow very tall. These may be 150 feet tall. _____________
Correct Answer
Emergent layer
Explanation
The given statement mentions that some tree species grow very tall, up to 150 feet. The term "emergent" refers to something that emerges or rises above the rest. In the context of forests, the emergent layer refers to the highest layer of the forest canopy, consisting of the tallest trees that rise above the canopy. Therefore, the correct answer for this question is "Emergent layer."
