What is Ecology?
|
The ways organisms ineract with one and other in their enviroment,
|
|
|
What is a enviroment?
|
Living and non-living components
|
|
|
What is a Abiotic enviroment?
|
non-living component or physical factors: soil, rainfall, sunlight, temperatures
|
|
|
What is a Biotic enviorment?
|
Living components and other organisms
|
|
|
Wat is the Ecological organization?
|
Individual - 1 Organisms
Population - Organisms of the same species in the same area Community - Several populations in the same area Ecosystem - Community plus abiotic factors |
|
|
What are the Biogeochemical cycles?
|
hydrologic, phosphorus, nitrogen, and carbon
|
|
|
What is a closed community>
|
They have sharp boundaries
|
|
|
What is the Ecology of individuals?
|
Homeostasis - Delicate balance
Components - Physiology Ecology Temp. & Water balance Light & Biological cycle |
|
|
What is the ecology of populations?
|
Properties of populations, Patterns of distribution & density, Intraspecific Competition, population dynamics, Growth and regulation, Altering population growth, Human Impact
|
|
|
What does the growth rate show?
|
How much the enviroment has grown over time
|
|
|
How is human population important?
|
It's important by showing how much humans are onthe planet (needing housing etc.)
|
|
|
what is surviorship?
|
The % of the remaining populatiion over time
|
|
|
Describe Taiga of North America
|
-2nd largest forest in the world
-Ring Artic between Artic and Deciduous Forest – 50 to 60 degrees North Latitude -Upper elevations of mountains |
|
|
What is type 1 survivorship ?
|
The individuals that live out there life span and die
|
|
|
What is type 2 survivorship?
|
Indivivuals that die a a constant rate (birds, rodents , and perennial plants.
|
|
|
wHAT IS TYPE 3 SURVIVORSHIP?
|
Individuals that die early in life (fishies, Invertebrates , plants)
|
|
|
What is a open community?
|
They Lack boundaries
|
|
|
What is the trophic Structure of communities?
|
Food chains, food web,
|
|
|
What is Neutral interaction?
|
When two species do not interact
|
|
|
What is Mutualism interact?
|
they both benefit *species*
|
|
|
What is commensalism?
|
One benefit, another is neutral
|
|
|
What is Parasitism interaction?
|
When one is benefited, and other is harmed
|
|
|
What is Predation interaction?
|
One has a benefit, another is dead
|
|
|
what is the food chain?
|
Rose plant -> Aphids -> Beetle -> Chameleon -> Hawk (example)
|
|
|
What is a Ecological pyramid?
|
A graph showing tropic level numbers in the area.
|
|
|
Numbers Pyramid
|
Compares tropic levels
|
|
|
What is a biomass pyramid?
|
Compares dry weight organism in a tropic level
|
|
|
what is a energy pyramid?
|
Shows the total energy in a tropic level
|
|
|
List environmental importance of the Taiga
|
-contains abundant amounts of carbon
-creates oxygen -rejuvenates soil and nutrients -marshes gives habitats for large amounts of birds and fishes |
|
|
what are some types of plants in the Taiga?
|
-Conifers are important producers
-Latitude and altitude effects species -Berry shrubs urgent to birds, mammals, and people |
|
|
Plant Adaptations
|
-trees have upside down cone shape, so snow can slide off he branches
-branches are flexible to hold large amounts of snow -trees grow in a group to defend themselves from the cold -needles waxy protects themselves from decreasing temperatures and keep from drying -thick bark protects inside layers from thermal temperatures and cones defends the seeds |
|
|
Types of Animals
|
-millions of insects in the summer
-3 billion insect-eating birds breed each year -predators feeding on small mammals |
