In every environment, there must be abiotic components. These abiotic components are
nonliving chemical and physical factors such as temperature, light, water, and nutrients.
The biotic factors of an environment include all the living things called biota in an
environment. These biotic factors rely on the abiotic factors for survival.
4. Distinguish among organismal ecology, population ecology, community ecology,
ecosystem ecology, and landscape ecology.
Organismal- morphology, physiology, behavior
Population- population density, distribution, age, structure, etc
Community- how species affect community structure and organization
Ecosystem- energy flow, cycling of chemicals
Landscape- past, present, future patterns of landscape us.
Organismal ecology studies the morphological, physiological, and behavior traits of
organisms in their environment. Population ecology studies population density,
distribution, age, structure, etc. Community ecology studies how species affect community
structure and organization. Ecosystem ecology studies energy flow and the cycling of
chemicals throughout and environment. Landscape ecology studies the past, present, and
future patterns of landscape us and ecosystem management and the biodiversity of
5. Clarify the difference between ecology and environmentalism.
