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 키워드 환경생태학, 열대우림, 생태학, 생태계, 영문
