Scienctific discipline in which the relationships among living organisms and the interactions the organisms have with their environement are studied
Ecology
The ability of any organism to survive when subjected to abiotic factors or biotic factors
Tolerance
The close relationship that exists when two or more species live together
Symbiosis
What 4 things does the biosphere include?
Land, oceans, air, and all living things.
What are the two most important ecological terms?
Ecosystem and biosphere
Biosphere
Individual organism of a single species that share the same geographic location at the same time
Population
The relationship between two or more organisms that live closely together and benefit from eachother
mutualism
What is the biggest difference between an ecosystem and a biosphere?
A biosphere is the largest level of life, where an ecosystem is a smaller local area.
What are the levels of organization?
Biosphere, biome, ecosystem, biological community, population, organism
The living factors in an organism ennvrionment
Biotic Factors
a group of interacting populations that occupy the same geographic area at the same time
biological community
is a relationship in which one organism benefits and the other organism is neither helped or harmed
Commensalism
The biosphere is made up of two parts, what is one?
Biotic components
Example of an organism depending on another organism and nonliving factors in their environment to survive?
A wolf hunting a deer, bacteria living inside a human, a bee pollinating a flower.
The nonliving factors in an organism environment
is a biological community and all of the abiotic factors that affect it
ecosystem
A symbiotic relationship in which one organism benefits at the expense if another organism
Parasitism
What are examples of abiotic components in a biosphere?
Sunlight, water, air, rocks, and temp.
What do ecologists do?
They observe, experiment, and model using a variety of tools and methods.
Any abiotic factor that restricts the numbers, reproduction, or distubrbution, of organisms is callled a
a large group of ecosystems that share the same climate and similar types of communities
Biome
Example of Parasitism
Brown Headed cowbirds demonstrate brood parasitism because they rely on other bird species to build their nests and incubate their eggs.
Why do biologists break down the biosphere into smaller parts to study?
The biosphere is too diverse and complex to study as a whole.
When was ecology introduced?
The 12th century
