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?
Define an abiotic factor.
A non-living factor affecting species abundance and dispersal (Temperature, Sunlight, Wind, Soil Type, etc)
Rainfall affects dispersal of a population by changing a bend in a river between the population.
Abiotic
Who wrote Silent Spring, a book that led to the ban of DDT in the US?
Rachel Carson
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?
Which determines broad species distributions: climate or weather?
CLIMATE
Weather, because it is short term, is more likely to impact an individual organism rather than the entire population.
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
name the 4 main nutrient cycles of ecology
carbon, water, phosphorus, nitrogen
name the abiotic aspects of a biome
climate, weather, water, rocks
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
levels of organizations
organism, population, community, ecosystem, biome
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?
describe the steps in the water cycle
precipitation, watershed, runoff, lakes, aquifer, evaporation, clouds
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
Give five examples of an abiotic factor.
1) Soil Type
2) Temperature
3) Climate
4)Water
5)Wind
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.
