Terms
The science that studies the interactions between organisms and their environment.
What is Ecology?
This level of ecology forcuses on all organisms that occupy the same geographic area.
Community 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
What is the difference between weathering and erosion?
Weathering is the breakdown of rock into smaller pieces, while erosion is the carrying away of those small pieces of rock (sediment)
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?
The study of the land in an ecosystem. Usually the rocks and minerals
What is Geology
An ascaris nematode feeds on nutrients in the intestines of a pig.
Biotic (Predation)
Give two examples of agents of erosion.
Glaciers, water, sea, wind, gravity, human action, vegetation.
A major groupings of plant and animal communities defined by a dominant vegetation type is known as a what?
Biome
List three levels of ecology that we have discussed.
Population, community, and ecosystem ecology
Limiting factor in an ecosystem.
What is sun, water, oxygen etc.
A tiger affects the dispersal of gazelle by consuming newborn young.
Biotic (Predation)
What are two things humans can do to help prevent/slow down weathering and erosion?
Mesh fencing, keep crops/plants in place, keep soil moist, prevent runoff, use rocks to hold down soil on river banks, build seawalls and dunes.
All individuals of one species that inhabit a geographic area (they can interbreed).
Population
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?
Most necessary factor for life.
What is the sun (solar)
An ox-bird eats the parasites of the skin of a cow.
Biotic (Mutualism)
Explain how rain can be both mechanical and chemical weathering.
The force of the rain drops hitting a rock can physically break the rock into smaller, while the water can also cause the rock to chemically change (oxidize) and wear away.
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.
Name the different trophic levels (ie producer etc.)
What are producer, decomposer, consumer, secondary consumer and tertiary consumer. (Omnivore and Carnivore)
Give three 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
Explain how weathering, erosion, and deposition work together to break down and build up Earth's surface.
Long answer. See the outer banks examples.
