Terms
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
How many theories are there on how our moon formed?
4
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)
The process of making new products from materials that were used in another product.
What is recycling
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.
Solar radiation (increases/decreases) with increasing latitude?
(See picture on Lecture 24 slide 8)
Because of the tilt of the Earth, the most direct sunlight will hit at the equator. The farther away a spot on the Earth is from the equator, the less solar radiation it will receive.
A tiger affects the dispersal of gazelle by consuming newborn young.
Biotic (Predation)
The loss of living space due to human activity or catastrophic events.
What is habitat loss
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?
How do Earth's orbit and tilt create seasons?
Because of the change in solar radiation with each latitude due to tilt of the Earth, as the Earth rotates around the sun, different areas of the world are hit with varying levels of solar radiation throughout the year, thus creating "seasons." (See Lecture 24 slide 9)
An ox-bird eats the parasites of the skin of a cow.
Biotic (Mutualism)
Release of harmful materials into the environment.
What is pollution
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
Plants and animals that have migrated to places where they are not native.
What is an invasive species
