Populations In Ecosystems

Front 1

Population

Back 1

All the organisms of one species in a habitat at the same time.

Front 2

Community

Back 2

All the different populations in a habitat.

Front 3

Ecosystem

Back 3

An area in which organisms interact with each other and with their physical environment.

Front 4

Carrying Capacity

Back 4

The maximum size that a population can remain sustainable in an ecosystem.

Front 5

IntErspecific interactions

Back 5

Between individuals of diffErent species.

Front 6

IntrAspecific interactions

Back 6

Between individuals of the sAme species.

Front 7

Competition

Back 7

Can be inter/intraspecific and is when 2 or more organisms share a resource that is in limited supply.

Front 8

Examples of competition

Back 8

Plants-light, water, nutrients (phosphate)

Animals- Food, water, space (burrow, nesting), mate.

Front 9

Predation

Back 9

IntErspecific, the predator catches, kills and eats the prey for food. Predator population< Prey population. Predator size> Prey size.

Front 10

Species

Back 10

A group of individuals with similar featured that can interbreed to produce fertile offspring.

Front 11

Habitat

Back 11

The place where an organism lives, the physical environment.

Front 12

Environment

Back 12

The conditions surrounding an organism. Abiotic/ Biotic.

Front 13

Biotic factors

Back 13

The affect all other living organisms have on an individual, competition, predation and disease.

Front 14

Abiotic factors

Back 14

This is the effect of physical factors such as climate and soil structure.

Front 15

Niche

Back 15

The role of an organism within an ecosystem, this depends on its adaptations to feeding and the abiotic factors present

Front 16

The population growth pattern stages?

Back 16

Lag phase

Log phase

Stationary phase
