Ecology |
The study of interactions between organisms |
|
Biotic Factors |
All the components that make up the living part of an environment |
|
Abiotic Factors |
Factors that make up the non-living part of the environment |
|
Habitat |
The specific environment that an organism lives in it includes all biotic and abiotic factors |
|
Organismal ecology |
The adaptions that organisms must make to meet or overcome abiotic factors |
|
Population |
Group of individuals of the same species living together in a particular geographical area |
|
Community |
All organisms that inhabit a particular area |
|
Ecosystem |
Includes all the organisms plus all the abiotic factors that make up a certain area |
|
Biosphere |
The global sum of all the planets ecosystem |
|
Energy Source (Abiotic factor) |
Sunlight is very important, heat is another important quality needed for life, bacteria that derive energy from oxidization of inorganic material. |
|
List of Abiotic factors affecting growth |
Temperature, Water, Inorganic materials (phosphorous and nitrogen), fast moving water has more oxygen than stagnant water and wind and other natural weather patterns can affect ecosystems. |
|
Evolutionary adaptions (Physiological responses) |
Acclimation (getting used to a new environment). Blood vessels constrict which slows the loss of heat or a bird fluffing it's feathers to keep heat in. |
|
Evolutionary adaptions (Anatomical responses) |
Irreversible changes to our physiology. Environment affecting physical maturation of a species or their height/body size.
|
|
Evolutionary adaptions (Behavioral responses) |
Environment causing you to move to a new area or migrating underground during daytime/nighttime to avoid heat or predators. |
|
Biome |
Is a major terrestrial or aquatic bio zone characterized by specific vegetation or movement |
|
Lakes and Ponds |
Freshwater biomes that feature 3 zones the photic, aphotic and benthic realm |
|
Photic Zone |
The zone where light is still available for organisms |
|
Aphotic Zone |
Areas where light is too low to support photosynthesis |
|
Benthic Realm |
At the bottom of the lake/pond. Is made up of sand and other organic or inorganic material |
|
Phytoplankton |
The collective name for algea and other cyanobacteria that floats near the top of the lake or pond |
|
River/Stream |
Body of moving water, they support different organisms than lakes and ponds. Cold and narrow at the top while usually warmer and wider downstream |
|
Wetland |
A transitional biome between an aquatic and a terrestrial area. Usually partially or permanently covered by water |
|
Marine Biomes |
Oceans, Coral reafs etc..... |
|
Interdial Zone |
Zone that is covered during high tide and uncovered during low tide |
|
Continental shelf |
Shallow part of the ocean near the beginning |
|
Pelagic Region |
Open water of the ocean |
|
Zoolplankton |
Free floating organisms including microscopic ones (fish, bactirea, etc...) |
|
Coral reef |
Found in warm tropic waters in photic zones, it's the result of many years of coral build up |
|
Estuary |
The transitional area between a river and an ocean (salt levels range from very salty to almost fresh water). |
|
What affects bio diversity? |
Climate specifically the sun that warms everything. The different angles it hits the earth at create zones
|
|
Tropics |
The area between 30S and 30N (cancer and capricorn) that many of the rainforests are centered around. They're very hot and humid. Descending dry air absorbs moisture and pushes it back towards the tropic zones |
|
Temperate zones |
Areas that are between 30S and 30N and the north/south pole respectively |
|
Mountains affects on Biomes |
1.) Temperatures drop the higher you go, giving rise to changes in the environment. 2.) Mountains can cause what's called a rain shadow, blocking precipitation from the coast to further inland. |
|
Tropical Rainforests |
High temperature and high in precipitation centered around the equator. High canopies block out light so not many shrubs, usually vines and other plants need to grow on existing branches and trees to get to sunlight. |
|
Savanna
|
High temperatures, low precipitation and high chance of fire. Large grazers and their predators inhabit savannas (lions/zebra), not much vegetation usually only grows when there's rain. Located south of the tropics. |
|
Desert |
High temperatures and low precipitation. Driest of all biomes, vegetation is limited to water storing plants like cactus. |
|
Chapparal |
|
