the interaction of a community of living organisms with the abiotic parts of their environments
what is the order of community?
plants produce food by photosynthesis
animals eat plants
animals pollinate plants
animals eat other animals
animals use plant and animal materials to build nests and shelters
plants need nutrients from animal droppings and decay
what is interdependence?
the network of relationships between different organisms within a community, for example each species depends on other species for food, shelter, pollination, seed dispersal.
what is an ecosystem?
the interaction of a community of biotic (living) organisms with the abiotic (non-living) parts of their environment
what do plants and animals compete for in a community?
plants compete with each other for light, space, water, and mineral ions from soil.
animals compete with each other for food, mates and territory.
what is a stable community?
one where all of the species and environmental factors are in balance so that population sizes remain fairly constant.
what is an extremophile?
an organism that lives in an extreme environment, such as at high temps, pressures, salt concs and bacteria living in deep sea vents.
what is a functional adaptation?
internal processes or systems in an organism that give it a survival advantage
what is a behavioural adaptation?
something an animal does in response to an external stimulus in order to survive.
what is a structural adaptation?
physical features of an organism which allow them to compete with other animals
