1. What is an ecosys- The relationship between all living and non-living parts of a habitat
tem?
2. What are the 3 levels Individual organisms, populations, communities
of organisation in an
ecosystem?
3. What is a population Groups of individuals of the same species
in an ecosystem?
4. What is a community Made of many populations living together
in an ecosystem?
5. What is competition Organisms competing for resources
in an ecosystem?
6. What do plants com- Light, water, minerals from soil and space
pete for?
7. What do animals Food, mates and territory
compete for?
8. What is interdepen- When species rely on each other for food, shelter, pollination, seed dispersal
dence? etc
9. Why would removing Because of interdependence, it can affect the whole community
one species from an
ecosystem be bad for
an ecosystem?
10. What happens in a All species and environmental factors are in balance so that population size
stable community? stays fairly constant.

What is an example
of a stable communi-
ty?
12. What is an abiotic A non-living factor that effects the community
factor?
13. What is a biotic fac- A living factor that effects a community
tor?
14. What do abiotic fac- Light intensity, temperature, moisture levels, soil pH and mineral content,
tors include? wind intensity and direction, carbon dioxide levels (Plants), oxygen levels
(Aquatic animals)
15. What do biotic fac- Availability of food, new predators arriving, new pathogens, one species
tors include? out-competing another
16. What are adapta- Features that allow an organism to survive in the conditions that they normally
tions? live in
17. What is a structural A physical adaptation. Features an organism has such as fur, beaks etc
adaptation?
18. What is a behavioural Something an organism does to allow it to survive
adaptation?
19. What are functional An internal working or body process that allows an organism to survive
adaptations?
20. What are ex- Organisms that can live in extreme conditions such as high pressure, high
tremophiles? salt concentration, or high temperatures
21. What is an example A tardigrade
of an extremophile?
