B7 Ecology Flashcards
Habitat
the place where an organism lives
Population
all the organisms of one species living in a habitat
community
the populations of different species living in a habitat
abiotic factor
non living factors of the environment
biotic factor
living factors of the environment
ecosystem
the interaction of a community of living organisms with non living parts of their environment
exremophiles
live in extreme conditions e.g high temp
producer
makes own food using sun energy
primary consumer
eats the producer
secondary consumer
eats primary consumer
tertiary consumers
eat secondary consumers
Distribution
where an organism is found
quadrat
square frame enclosing a known area
what do plants compete for
light, space, water, mineral ions from soil
what do animals compete for?
territory, food, water and mayes
what’re the 3 types of adaptations
structural, behavioural, and functional
structural adaptation means
shape or colour
behavioural adaptation means
behaviour like migration
functional adaptation means
inside the body like metabolism
why are populations increasing
medicine, farming
how do humans put pressure on the environment
resources, higher standard of living, toxic chemicals from indistry
consequence of global warming
sea levels rise, changes in species distribution, migration patterns and reduction in biodiversity
what’re peat bogs
not fully decayed plants in waterlogged and acidic conditions
why are peat bogs drained
used as farmland or fuel
how do humans maintain biodiversity
breeding programmes
order of organisation
cell tissue organ organ system organism
