Biogeography and soil
• Biogeography is the study of how environment factors affect with life process of plants
and animal in terms of the locations and their distributions
• Ecosystems
o Interdependent relationships among living organisms and with their
environments
• Components of ecosystems
o Abiotic: any non living materials on ecosystem
o Producer
▪ Self nourished
▪ Plants
▪ photosynthesis
o Consumer
▪ Herbivores, carnivore, omnivore
o Decomposer
• Soil
o Inorganic materials
o Soil water
▪ Capillary water
▪ Gravitational water
o Soil air
▪ 50% of the soil volume (dry soil)
o Organic matter
▪ Humus
▪ Rotten, decomposed material from living organisms
Structure of the earth
• Earth materials and plate tectonics
o Remote sensing
o Seismic waves
o Seismograph
o P (primary ) waves
▪ Can travel through all materials; faster than S-waves
o S (secondary) waves
▪ Can only travel through solid materials; slower than P waves
Document Summary
Biogeography and soil: biogeography is the study of how environment factors affect with life process of plants and animal in terms of the locations and their distributions, ecosystems. Interdependent relationships among living organisms and with their environments: components of ecosystems, abiotic: any non living materials on ecosystem, producer, self nourished, plants, photosynthesis, consumer, herbivores, carnivore, omnivore, decomposer, soil. Inorganic materials: soil water, capillary water, gravitational water, soil air, 50% of the soil volume (dry soil, organic matter, humus, rotten, decomposed material from living organisms.
