| Term | Definition |
| The tropical rainforest | is a biome that has high temperatures and a large amount of rain. |
| Seasons in the tropical rainforest | vary mostly in the amount of rainfall, so it changes very little from season to season. |
| The layers of the tropical rainforest are | the canopy, the understory, and the forest floor. |
| The canopy | is the main layer where most of the animals live. |
| The understory | contains young trees and palms. |
| The forest floor | is the bottom layer. |
| Few plants can grow beneath the canopy | because the canopy layer prevents much of the sunlight from reaching the forest floor. |
| Vines | can grow from seeds on the forest floor and climb up trees as they grow. |
| The sandbox tree | has one adaptation that protects itself from animals that climb. |
| The adaptation of the sandbox tree | is its sharp spikes that squirt out poison sap when its bark is cut. |
| Some birds and animals that live in the tropical rainforest are | the South American toucan and parrot, and the hummingbird. |
| Monkeys | climb the canopy layer. |
| The monkey's hands, feet, and tails | are adaptaions that help them move in the trees. |
| Tropical rainforests | are located near the equator. |
