Principles of Ecology Chapter 2.1
Biotic & Abiotic FactorsLiving organisms Abiotic = Nonliving Soil,Air,Water Substrate
Population: Number of Individuals Same Species In an area or place
Community All the Plants & Animals In a given area? Community of Del Mar
Forest Community …………..
Ecosystem: Both biotic and abiotic factors in a large area:
Niche versus habitat Habitat = Place Niche = RoleProducer, Consumer or Decomposer Adaptations
Niche overlap? Do not overlap Competition eventually is harmfulSpecialized adaptation wins out
Organism Interrelationships:Beneficial Symbiosis= Living together Commensalism= Only one benefits Mutualism= Both benefit Harmful: Parasitism= One benefits & Host slowly harmed
Tape worm Parasite: You are harmed because it lives off your intestinal fluids Segments break off to form a new worm!
Lichen=Fungus + algae Fungi = carbon dioxide moisture Algae = foodOxygen MUTUAL SYMBIOSIS
