Organism and environment

Abiotic
Factor

Non-Living Parts
of an ecosystem

Water, Soil, Air,

Sunlight

Biotic
Factor

Living Parts of an

ecosystem

People, Animals,

plants

Community

All the populations

of different
species in the

same area at the

same time.

For example,
Lions, squirrels,
deer, and wild
boar form a...

Population

All the members

of the same
species in the

same area at the

same time.

All the meerkats

that live in an
area form the...

Species

A group of

organisms that

have similar traits
and are able to

produce offspring.

There are different
types of bears but
they all share similar

triats.

Organism
A living Thing

Competition

The demand for

resources (food, water,

shelter) that are in
short supply in a

community

sharks, dolphins, and
seabirds often eat the

same type of fish in
ocean ecosystems
Sometimes fight to
obtain there food.

Limiting
Factor

Anything that restricts

the size of a
population

There is not enough
available sunlight so

green plants cannot go
through photosynthesis
the herbivore population

will be affected.

Carrying
Capacity

The largest number of

individuals of one
species that an
environment can

support

Population of meerkat

can no longer grow
because there is not

enough food available.

Biodiversity

Variety of plants and
animals species in an
ecosystem leads to

great stability.

The different plants,
animals and micro-

organisms, their genes,

and the terrestrial,

marine and freshwater of

an ecosystems
