🌍 Equatorial Rainforest Notes 📍 Location Equatorial rainforests are found near the Equator (0° latitude), between about 5° North and 5° South. Major regions: South America – Amazon Rainforest (largest) Africa – Congo Basin Asia – Southeast Asia Rainforests 🌦️ Climate Hot all year round (average: 25–28°C) Heavy rainfall (over 2000 mm per year) High humidity (very moist air) No distinct seasons (same weather throughout the year) 🌍 Examples of Countries Brazil Democratic Republic of the Congo Indonesia Malaysia Colombia 🌳 Characteristics of Vegetation (Plants) Dense and thick forest (trees grow close together) Tall trees (can reach over 40–60 m) Evergreen trees (do not lose leaves) Broad leaves to capture sunlight Layers (stratification): Emergent layer (tallest trees) Canopy (forms a “roof”) Understory Forest floor Lianas (climbing plants) and creepers Buttress roots for support in shallow soils 🐒 Characteristics of Animals Very high biodiversity (many species) Animals are adapted to live in trees (arboreal) Camouflage to hide from predators Bright colours (e.g. birds, frogs) Examples: Monkeys and apes Snakes Birds (parrots) Insects (many species) Frogs 🌱 Why There Is Little / No Humus Content Humus = decayed organic matter in soil. In equatorial rainforests: High temperatures → speed up decomposition Heavy rainfall → washes nutrients away (leaching) Plants quickly absorb nutrients before humus forms Thin soil layer with very little organic matter 👉 Result: Soil is not very fertile despite thick vegetation.
