1. ecosystems Flashcards
habitat
where an orgnism lives
populations
all the organisms of one species in a habitat
community
populations of different species in a habitat
ecosystem
community and all non living (abiotic ) conditions in the area in which it lives
abiotic conditions
non living feature of a ecosystem e.g. temperature and availability of water
biotic conditions
the living features of an ecosystem e,g, presence of predators or food
niche
the role of a species within its habitat e.g. what it eats and when it feeds includes: biotic interactions (the organism it eats and those its eaten by) abiotic interactions (oxygen an organism breathes in)
adaptation
a feature that members of a species have that increases their chance of survival and reproduction
every species has its unique niche
if 2 species try occupy same niche they will compete and one will be more successful
example of adaptations to abiotic conditions
e.g. how much land they can live on
otters webbed paws - walk on land and swim effectively
example of adaptations to biotic conditions
e.g. access to another source of food
otters use rocks to smash open shell fish and clams
adaptations can be
physiological (processes inside body)
behavioural (way an organism acts)
anatomical (structural features of body)
