Ch. 3 - Introducing behaviour

Gausess

Gausess

________ competitive exclusion principle: applies when niches are sufficiently similar.

Anti coagulants

________ in the saliva of bloodsucking parasites.

biotic factors

Limits of realised niche: Set by ________ such as interspecific competition or predation.

Niche

________: The way an organism has adapted in response to its habitat.

Physical tolerance

________: How much an organism can withstand.

range of physiological tolerance

Organisms only inhabit areas where abiotic factors within ________.

Physical tolerance

How much an organism can withstand

Structural adaptations

adaptations to the structure of the organisms body ie

Behavioural adaptations

adaptations to the behaviour of the organism that increase its chance of survival and reproduction ie

Physiological adaptations

adaptations to the chemical processes of an organism that increase its chance of survival and reproduction ie

Niche

The way an organism has adapted in response to its habitat

Fundamental niche

The niche an organism would occupy if all necessary environmental conditions are present

Limits of fundamental niche

Set by limits of the organisms physiological tolerances to abiotic factors

Limits of realised niche

Set by biotic factors such as interspecific competition or predation

Vacant niche

A niche that has not been inhabited or opened up due to the extinction of a species previously occupying the niche

Gausess competitive exclusion principle

applies when niches are sufficiently similar

abiotic factors

_____________ are non-living components of an ecosystem that can affect the survival and behavior of living organisms. Examples include temperature, water availability, sunlight, and soil composition.
