, Basic Ecology patterns and processes of how species interact with each other and the
environment
Basic Ecology vs Applied Ecology Basic - fundamental about the nature of the species, population, ecosystem, and
their processes
Applied - can be applied to conservation, restoration, or management
Levels of Ecological Organization Individual
Population
Community
Ecosystem
Individual a single unit capable of independent existence
Population a group of the same species living in the same area at the same time (interbreeding
among themselves for reproduction)
Physical or temporal barriers separate populations
Community all of the species living (Biotic Factors) in a certain area at the same time
(interactions in food webs and competition)
Ecosystem a functional unit of nature that includes abiotic and biotic factors in a habitat
(terrestrial and aquatic ecosystem)
Organismal Relationships no perfect equilibrium
They regulate populations and communities
They change over time naturally - nature is dynamic
They change with human influence
Harvesting, Climate Change, Accidental species introduction
Trophic (feeding) Relationship Groups Primary Producers
Consumers/heterotrophs
Primary Producers create their own food by converting inorganic molecules into organic molecules like
sugar and amino acids for fuel
Consumers/heterotrophs cannot create their own food, consume primary producer or another consumer
Consumer Groups Herbivory
Parasitism
Decomposition
Herbivory animals eating primary producers (plants/algae/kelp)
Lethal Herbivory complete consumption
