Why do plants in the lower layers of the rainforest grow well despite limited sunlight?

• They do not need sunlight to make food.

• They have adapted to survive in low light conditions.

• They grow taller than the canopy trees.

• They absorb nutrients from the rain.

What is the role of decomposers in the rainforest?

• They provide shelter for animals.

• They break down dead plants and animals to return nutrients to the soil.

• They hunt and eat smaller animals.

• They produce their own food using sunlight.

What might happen if decomposers were removed from the rainforest ecosystem?

• The amount of oxygen in the air would increase.

• The rainforest soil would lose important nutrients.

• Rainfall in the rainforest would stop.

• Carnivores would have more food to eat.

Why is the rainforest considered one of the most biodiverse ecosystems?

• It has only a few types of plants and animals.

• The warm climate and high rainfall support a wide variety of life.

• There are no predators, so animals live longer.

• Only herbivores and omnivores live there.

Which of the following is an example of an omnivore in the rainforest?

• sloth

• harpy eagle

• capuchin monkey

• leafcutter ant

What conclusion can be drawn about the importance of rain in the rainforest?

What can be inferred about the rainforest soil based on the passage?

How does deforestation most directly affect the biodiversity of the rainforest?

• It increases the number of plant species.

• It creates more habitats for animals.

Which detail from the passage supports the idea that the rainforest has a balanced ecosystem?

• The rainforest receives between 80 to 400 inches of rain per year.

• Predators keep prey populations under control, and decomposers recycle nutrients back into the soil.

• The rainforest is found near the equator in places like South America, Africa, and Southeast Asia.

• The soil in the rainforest is not very rich in nutrients.
