A group of similar organisms that can reproduce to produce FERTILE offspring
Species
all of the organisms of one species in an ecosystem
Population
All organisms of all populations in an ecosystem
Community
The study of inter-relationships between organisms & their environment
This environment includes living (biotic) factors (e.g. competition & predation) & non-living (abiotic) factors (e.g. temperature & rainfall).
Ecology
A self contained area including the biotic (living) community and abiotic (non-living) components interacting with one another
Ecosystem
the category of living factors in the environment of an organism that affect population size
Biotic factors
Two examples of biotic factors that affect the population size of an organism
disease,
predation,
competition
the non-living / physical part of an ecosystem that can affect population size
Abiotic factors
Give two examples of abiotic factors
temperature,
oxygen concentration,
pH,
light,
carbon dioxide concentration
The place where an organism lives
Habitat
This describes how an organism fits into the environment. It describes what a species is like, where it occurs, how it behaves, its interactions with other species and how it responds to its environment.
Niche
Where one organism is consumed by another
Predation
Competition between organisms of the SAME species e.g. for food or mates
Intraspecific competition
competition between organisms of DIFFERENT species e.g. for food
Interspecific competition
Differences between organisms of the same species
Intraspecific variation
The differences between organisms of different species.
Interspecific variation
