5 Biodiversity and Ecology II
Basic concepts
study of interactions btw organisms and environment
abiotic: non-living component
biotic: living component
Basic Terminologies
Individuals
any living thing or organism
Population
grp of organism of same species
Community
population live tgt, different species relationship
Ecosystem
consist of biotic and abiotic
community is part of ecosystem
Biomes
a set of ecosystem
sharing similar characteristics with their abiotic factors
Biosphere
part of earth inhabited by organism
air, water, land layer
Biomes
Tundra
extremely low temp./ coldest environment
Eg: caribou
Coniferous forest
evergreen conifers
Eg: migratory animals
Temperate deciduous forest
Temperate evergreen woodlands
Temperate grassland
dry and cool
Eg: herbivores and burrowing mammals
Tropical grassland (savannah)
Eg: grazing animals
Tropical rainforest
heavy annual rainfall
Desert
Interactions btw biotic factors
Parasitism +-
Endoparasite
live whithin host
Eg: tapeworms
Ectoparasite
outside the host
Eg: Rafflesia
Commensalism +o
Eg: remora fish with shark, barnacles with whale
transport, food, protection
Mutualism ++
Eg: hermit crab(protection) with sea anemones(locomotion & food)
Eg: honey bees(nectar) with flowering plant(cross-pollination)
Predation
improve quality of prey population
Competition
Intraspecific
within same species
Interspecific
different species with similar niche
Habitat
Microhabitat
particular location where an individual species normally found
Niche
role of an organism in an ecosystem
different species in same habitat - different niche
2 organisms with same niche can't occupy same habitat, else they compete and one will left
