1. Ecology
Abiotic
Biotic
Ecosystem
Populations
Carrying
Capacity
All the living and non-living
components of a particular area.
An ecological factor that makes up
part of the non- biological
environment of an organism. E.g
temperature, pH & humidity.
A group of individuals of the same
species that occupy the same
habitat at the same time.
An ecological factor that makes up
part of the living environment of an
organism. E.g food availability,
competition and predation.
The maximum population size of
the species that the environment
can sustain indefinitely, given that
food, habitat, water, and other
necessities are available in the
environment.
All the living organisms present in
an ecosystem at a given time.

2. Interspecific
competition
Intraspecific
competition
The study of the inter-relationships
between organisms and their
environment.
Competition between organisms of
the same species.

3. Community Habitat
Niche Species
Microhabitat Limiting
Factors
The place where an organism
normally lives and which is
characterised by physical
conditions and the types of other
organisms present.
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.
A variable that limits the rate of a
chemical reaction.
A group of similar organism that
can breed together to produce a
fertile offspring.
A smaller unit within a habitat that
possesses its own microclimate.
Competition between organisms of
different species.
