The science that studies the interactions between organisms and their environment.
What is Ecology?
This level of ecology studies how changes in one area of the globe affect other regions of the world.
What is global ecology?
Rainfall affects dispersal of a population by changing a bend in a river between the population.
Abiotic
List the six levels of ecology from smallest to largest.
Organismal, population, community, ecosystem, biome, and global biosphere
This consists of all the organisms in a particular region, along with nonliving components.
What is an ecosystem?
The goal of this level of ecology is to understand factors affecting population growth, density, and size. It also involves studies of species interactions such as predation and mutualism.
What is population ecology?
An ascaris nematode feeds on nutrients in the intestines of a pig.
Biotic (Predation)
What other fields can ecology be linked to?
Genetics, physiology, behavior, paleontology, evolutionary biology
A major groupings of plant and animal communities defined by a dominant vegetation type is known as a what?
Biome
What are the two subdivisions of organismal ecology?
*Physiological ecology-how organisms are physiologically adapted to their environment
*Behavioral ecology-how the behavior of an individual organism contributes to survival and reproductive success.
A tiger affects the dispersal of gazelle by consuming newborn young.
Biotic (Predation)
Living factors that affect species abundance and dispersal is known as a...?
Biotic Factor
Define physiological ecology.
The goal of this level of ecology is to study how nutrients and energy moves between organisms and the surrounding atmosphere, soil, or water.
What is ecosystem ecology?
An ox-bird eats the parasites of the skin of a cow.
Biotic (Mutualism)
How is ecology different from advocacy?
Environmentalism is advocacy focused on conservation and preservation of life on Earth whereas ecology provides scientific understanding of living things and their environments.
What is the difference between climate and weather?
Climate: The prevailing long-term weather conditions found in an area.
Weather: Specific short-term atmospheric conditions of temperature, precipitation, sunlight, and wind.
List the six levels of ecology from smallest to largest.
Organismal, population, community, ecosystem, landscape, and global
Worms are unable to living in a certain environment because of the soil type.
Abiotic
What is an introduced species?
Species brought into regions by human actions either intentionally or unintentionally.
