Other living things that can affect a population (parasite).
Abiotic factors
Non-living things that can affect a population (light-intensity).
3 biotic factors
New pathogen, new predators, interspecific competition.
3 Abiotic factors
Light-intensity, temperature, moisture levels.
What resources do animals compete for ?
Animals compete for resources, such as food, water, shelter, and even competing to try and find a mate.
What resources do plants compete for ?
Plants mainly compete for light and water intake, that is needed for photosynthesis to occur.
What is an extremophile ?
An extremophile are organisms that survive and can reproduce in the most difficult conditions, for example : extreme salt content, extreme temperature, etc…
What is a structural adaptation ?
They are related to physical structures - shape, colour etc.
What is a behavioural adaptation ?
Features related to short or long-term behaviours - migration, basking, tool use etc.
What is a functional adaptation ?
Features related to processes - usually internal, cellular processes.
