1.A life cycle is the set of _______________________________ that an organism goes through during its _________________.

3. The plant grows into the soil and then breaks out of the soil. This stage is called the _______________________________.

In a tropical rain forest, tall trees crowd together, blocking the path of sunlight to the wet forest floor. Among the plants adapted to these conditions are climbers, such as vines that grow up along the tree trunks. Other plants, such as orchids, grow attached to tree branches and are not rooted in the ground. Even a small area of forest provides various habitats for vast numbers of animal and plant species. Many insects and birds are plant pollinators. Fruit-­eating animals, such as birds and bats, spread seeds. Insects, fungi, and bacteria break down plant and animal matter, releasing nutrients into the soil. Predators, such as jaguars and snakes, feed on smaller animals.
