B16 Adaption and Competition Flashcards
What is an ecosystem
It is the interaction of a community of living organisms with abiotic parts
What happens in a community
species depend on other species for food, shelter, pollination
what is interdependence
It is when species rely on other species for things
What is a stable community
It is one where all species and environmental factors are in balance and everything remains fairly constant
What abiotic factors affect communities
light intensity
temperature
soil pH
Carbon dioxide levels
What biotic factors may affect communities
Availability of food
new predators
new pathogens
new competitors
What do quadrats do
They are squares used to measure the size of a population of plants
What is quantitative sampling
It is taking readings and then finding a mean when sampling an area
What is a transect
It is a line used to sample along when measuring the distribution of organisms
What do animals compete for
food
territory
mates
what type of animals are most likely to win the competition
The animals which are best adapted
What do plants compete for
light
water
nutrients
space to grow
what are extremophiles adapted for
extreme condition of salt
temperature
pressure
what are adaptions
These are features of the animal or plant that make it possible for them to survive
what are some adaptions of plants
hang off large trees
rely on bats to pollinate their flowers
