The non-living components of the environment, such as sunlight, rock types and climate that affect ecological functions are:

• biotic

• abiotic

• ecosystems

• population

The term for all members of the same species in a habitat, at any one time is

• biotic

• abiotic

• the ecosystem

• the population

The upper layer of the Earth, which includes the Oceanic and Continental crusts and parts of the cooler, solid upper mantle, is:

• the atmosphere

• the geosphere

• the lithosphere

• the hydrosphere

Look at this list.

i: It supports many species not found in any of the bordering ecosystems.

ii: It may contain a mixture of species including many unique to the area.

iii: It prevents organisms from adjacent ecosystems from migrating or mixing.

iv: It contains plants and animals from adjacent regions.

The features of an ecotone are:

• i, ii and iii

• i, ii and iv

• i, iii and iv

• ii, iii and iv

The process by which nitrogen is returned to the atmosphere is carried out by:

• denitrifying bacteria

• nitrogen-fixing bacteria

• decomposers

• nitrifying bacteria

A series of events that will occur after a forest fire is called:

• primary succession

• secondary succession

• tertiary succession

• climax community

If an ecosystem goes beyond its climax community, this can lead to:

• evolution

• negative feedback

• limiting factor

• biotic potential

The table shows the species diversity for plants in four aquatic systems.

Ecosystem                       Species Diversity
A                                            5.8
B                                            2.3
C                                            1.0
D                                            0.2

The least stable ecosystem is:

• A

• B

• C

• D

• the lithosphere

• the mesosphere

• the atmosphere

• the biosphere

A place where an organism lives is called:

• a biome

• a habitat

• an ecotone

• an acetone
