What are the 6 Levels of the Ecological Hierarchy?

Organismal, Population, Community, Ecosystem, Landscape, Global (biosphere).

This is the study of how an individual interacts with its environment, how its behavioural, physical and physiological adaptions make it suited for its habitat etc.

This is the study of how a group of individuals of one species are affected by different factors. Such as studying which factors affect the rate of reproduction of a population.

The study of how a group of populations interact together and how this changes the structure of the community, transfer of energy between them, predator-prey relationships and competition are all involved here

Studying the interaction of the physical (abiotic) and communities within the ecosystem. Mainly focuses on Energy and compound transfer etc.

Studying the interactions of many ecosystems that mesh together, monitoring energy, chemical and organism movement between them.

This studies how the changing ecosystems affect the wider global biosphere, such as the changing of the Amazon landscape and its effects on the worlds CO2 levels.

The traits which lead to the determination of the schedule of reproduction in a species. Natural selection selected.

This is a reproductive strategy in which the organism will only produce offspring once in it's lifetime but will produce many, many offspring in this time. Organism dies after. Favoured in Harsher, low competition environments.

This is when an organism has many reproductive cycles in its lifetime. Parental care is typically given to produce larger yet much fewer offspring.

Question	Answer
What are the 6 Levels of the Ecological Hierarchy?	Organismal, Population, Community, Ecosystem, Landscape, Global (biosphere).
Organismal Ecology:	This is the study of how an individual interacts with its environment, how its behavioural, physical and physiological adaptions make it suited for its habitat etc.
Population Ecology:	This is the study of how a group of individuals of one species are affected by different factors. Such as studying which factors affect the rate of reproduction of a population.
Community Ecology:	The study of how a group of populations interact together and how this changes the structure of the community, transfer of energy between them, predator-prey relationships and competition are all involved here
Ecosystem Ecology:	Studying the interaction of the physical (abiotic) and communities within the ecosystem. Mainly focuses on Energy and compound transfer etc.
Landscape Ecology:	Studying the interactions of many ecosystems that mesh together, monitoring energy, chemical and organism movement between them.
Biosphere Ecology:	This studies how the changing ecosystems affect the wider global biosphere, such as the changing of the Amazon landscape and its effects on the worlds CO2 levels.
Life History:	The traits which lead to the determination of the schedule of reproduction in a species. Natural selection selected.
Semelparity:	This is a reproductive strategy in which the organism will only produce offspring once in it's lifetime but will produce many, many offspring in this time. Organism dies after. Favoured in Harsher, low competition environments.
Iteroparity:	This is when an organism has many reproductive cycles in its lifetime. Parental care is typically given to produce larger yet much fewer offspring.
