Study Notes
Climate Characteristics
- Tropical rainforests are located near the equator across South America, Central America, Africa, Southeast Asia, and Australia.
- The climate is consistently warm and wet, with temperatures ranging from 68 to 93 degrees Fahrenheit.
- Rainfall averages between 60 - 200 inches annually; the region experiences a wet season and a dry season of approximately equal length.
- Soil in rainforests is nutrient-poor and damp, washing away essential nutrients due to heavy precipitation.
Forest Composition
- Rainforests are dense and support diverse plant and animal life, benefiting from high biodiversity.
- Notable tree species include the Kapok tree and the Giant Mahogany tree, both capable of growing over 100 feet tall.
- The Astrocaryum fruit tree and other fruit-bearing trees thrive, while shrubs, palms, and woody plants flourishes on the dim forest floor.
- Some plants, like liana vines, have roots in the ground but climb high to access sunlight, maximizing photosynthesis.
- Non-rooted plants like ferns, orchids, and bromeliads also contribute to forest diversity.
Animal Life and Ecosystem Roles
- Red-eyed tree frogs inhabit the rainforest, while birds, bats, and insects occupy the tree canopy.
- Key avian species include Harpy Eagles, which prey on small mammals and reptiles like sloths and snakes.
- Howler Monkeys feed on fruit and leaves, contributing to seed dispersal.
- Jaguars serve as apex predators, regulating populations of large mammals and thriving both on the ground and in trees.
- Capybaras are herbivorous rodents that reside on the forest floor and near water sources, with an awareness of predators like jaguars and anacondas.
Decomposition and Nutrient Cycling
- Decomposers play a crucial role in nutrient recycling within the rainforest ecosystem.
- Visible decomposers include snails, ants, worms, and termites, while microscopic decomposers like bacteria and fungi break down organic material.
- The breakdown of waste contributes essential nutrients to the soil, vital for plant growth despite the overall nutrient-poor condition.
