1. ecosystem all the organisms living in an area together
and all the abiotic factors
2. habitat the place where an organism lives
3. population all the organisms in a species living in the
same habitat
4. community all organisms of different species living in
the same habitat interacting with each other
5. biotic living factors in an ecosystem i.e. mice,
plants, fish
6. abiotic non-living factors in an ecosystem i.e. water,
sunlight, rocks, soil
7. endemic a species which is only native to one geo-
graphical location
8. species a group of organisms which can reproduce
fertile offspring together
9. interspecific competition competition between two organisms from
different species i.e. robin and a blue tit com-
peting for water, bugs, nests
10. intraspecific competition competition between two organisms of the
same species i.e. two lions competing for a
mate
11. succession A series of predictable and orderly changes
within an ecosystem over time.
12. primary succession when newly formed rock becomes inhabited
by a pioneer species for the first time caus-
ing succession to begin
13. secondary succession

when plants are all destroyed but the soil
remains so plant life restarts i.e. caused by
forest fire or deforestation
14. pioneer species the first species to inhabit a newly formed
rock i.e. lichen
15. sere a stage of succession
16. climax community the highest level of succession which has
the most complex organisms and is a stable
environment
17. process of succession 1. newly formed rock from lava is inhabited
by lichen
2. lichen dies and is decomposed forming
a basic soil which holds little nutrients and
water
3. mosses grow using water and nutrients in
soil
4. mosses die adding to soil increasing soil
quality
5. this repeats with grasses, shrubs, bushes
and then trees
6. each stage deepens the soil and the last
stage will reach climax community
18. plagioclimax when succession is forced to stop due to
human activity such as moving a lawn
19. light dependent reaction part of photosynthesis that requires light en-
ergy
