In general, a rainforest is a forested area that receives over 60 inches of rain per year.
1. Climate: High humidity is the main cause of high temperatures and the abundant rainfall.
2. Soil: Tropical rainforests grow in nutrient-poor soil and more nutrients are found in the living plants of the rainforest than in the supporting environment.
3. Location and Altitude: Only 6% of the Earth’s surface / the Earth's orbit is tilted about 23 ° 27
4. Layers: Forest Floor – Understory Layer – Canopy Layer – Emergent Layer
(2) Interactions in Tropical Rainforest
2-1. Ecosystem members
1) Primary producers: occupy the base of the energy pyramid.
2) Primary consumers: consume autotrophs as their food and derive energy for their survival.
3) Secondary consumers: feed on the autotrophs as well as primary consumers, their energy source.
4) Tertiary consumers: Carnivores that feed on the secondary consumers.
5) Decomposers: break down dead plants, animals, and the waste of other organisms
2-2. 3 kinds of interactions
1) Symbiosis (Interaction, Relationship) : Mutualism, Commensalism, and Parasitism
2) Predators vs Prey: Predator eats another, and Prey is an Animal that is eaten by a predator.
3) - Cooperation: an interaction in which organisms work in a way that benefits them all.
-Competition: the struggle between individuals or different populations for a limited resource
(3)Tropical Rainforest Biodiversity
The world's most spectacular example of a living ecosystem and the ultimate in biodiversity
3-1. Tropical Rainforest Plants
1) Plants on plants - Epiphytes which grow on other plants, and draw all of nutrients from the air.
2) Plants protection - Spines and thorns, smooth or shedding bark, leaves with holes & internal toxins
