b. contain only bacteria and other microorganisms.

c. use energy from photosynthesis in the photic zone.

d. use energy produced by chemoautotrophs that oxidize sulfur.

3.

Select one:

a. 0° N and S

b. 15° N and S

c. 30° N and S

Answer 1

1.option c

EXPLINATION

The chaprral biome is adapted to periodic fire.not the temperate grassland; The temprate grassland is characterised by grasses trees are absent and large shrubs are also absent

2. option d

Deep sea hydrothermal vents communities use energy produced by chemoautotrophs that oxidixe sulfur.

EXPLINATION

Chemoautotrops are the orgnaism which obtain their energy from the oxidation of the inorganic molecule.In deep sea hydrothermal vents ,the water is rich in dissolved mineral like sulfur which support to large population of chemoautotrophs therefore they oxidise the sulfur for energy.

3.option c

EXPLINATION

Most of the desert and arid zones are located near 30 degree north latitude and 30 degree south latitude. because hot air rises at the equator where the land receives greatest amount of sun energy.
