Intro to Ecology

TermDefinition
Ecology -The study of how organisms interact with one another other and the environment they live in.
Five major levels we study ecology at -Individual to Population to Community to Ecosystem to Biosphere
Individual Organisms -Smallest unit we study ecology at -One Organism
Population -Second smallest level of ecology after individual organisms. -Defined as a group of organisms from SAME species living in SAME place at the SAME time.
Community -Third level of studying ecology after population. -Defined as ALL LIVING things living on a specific reef on an island in Indonesia. -Biologists might study how a particular reef is doing but only looking at the living organisms.
Ecosystem -Fourth level of studying ecology after community. -Defined as ALL LIVING AND NON-LIVING components on a specific reef on an island in Indonesia. -Biologists might study how a particular reef is doing but also looking at the non-living factors.
Biosphere -Fifth & Broadest level of studying ecology after ecosystem. -Defined as all the ecosystems on Earth put together or looking at issues on a planetary level.
"Patchy" -Term used to describe how the biosphere is broken up into many different habitats.
Habitat -Specific places in the planet where organisms live.
Abiotic Factors -"A" means without and "bio" means life. -Defined as the non-living parts of a habitat such as sunlight, rainfall, humidity, temperature, and so on that influence what organisms can live there.
Biotic Factors -The living components in a habitat. -Living organisms interact with one another and end up altering the environment itself.
Sunlight -Key abiotic factor needed for photosynthesis.
Water -Key abiotic factor needed for photosynthesis and respiration.
Microclimates -Small habitats within a larger habitat created by small changes in abiotic factors.
Zonation -Microhabitats present Horizontal in a habitat. -Abiotic factors vary along the ground (horizontally).
Stratification -Microhabitats present vertical in a habitat. -Abiotic factors vary from ground to tree level in the climate (vertically).
