interactions and inter dependencies between living
organism and the physical environment.

Answer 5

Interactions:

Question 6

are the world’s major communities.

Answer 6

Biomes

Question 7

The biosphere is divided into biomes.

Answer 7

❑ Aquatic
❑ Forest
❑ Desert
❑ Tundra

Question 8

This biome encompasses all bodies of
water on Earth, including freshwater and marine
environments.

Answer 8

❑Aquatic

Question 9

Aquatic biomes are further divided into
freshwater biomes (e.g.,

Answer 9

rivers, lakes, wetlands)

Question 10

marine biomes (e.g.,

Answer 10

oceans, coral reefs, estuaries).

Question 11

are characterized by dense
vegetation dominated by trees. It also includes
tropical rainforests, temperate forests, and boreal
forests (also known as taiga). These biomes play a
crucial role in regulating

Answer 11

❑Forest

Question 12

Deserts are arid landscapes characterized by
low precipitation and extreme temperatures.

Answer 12

❑Desert

Question 13

hot deserts

Answer 13

Sahara, Sonoran Desert

Question 14

cold
deserts

Answer 14

Gobi Desert, Antarctica

Question 15

is a cold, treeless biome found in
the Arctic and Antarctic regions and at high altitudes. It
is characterized by low temperatures, permafrost, and
short growing seasons. Its vegetation mainly
consists of grasses, mosses, lichens, and shrubs
adapted to cold climates.

Answer 15

❑Tundra

Question 16

4 crucial roles of the biosphere

Answer 16

Oxygen Cycle
Water Cycle (Hydrological Cycle)
Carbon Cycle
Nitrogen Cycle

Question 17

it is the The entire cycle can be
summarized as, the oxygen
cycle begins with the process
of photosynthesis in the
presence of sunlight, releases
oxygen back into the
atmosphere, which humans
and animals breathe in oxygen
and breathe out carbon
dioxide, and again linking back
to the plants.

Answer 17

Oxygen Cycle

Question 18

it is the The water cycle consists of
three major processes: evaporation,
condensation, and precipitation.
Liquid water evaporates into water
vapor, condenses to form clouds,
and precipitates back to earth in the
form of rain and snow.

Answer 18

Water Cycle (Hydrological Cycle)

Question 19

it is the The carbon cycle is nature’s way of
reusing carbon atoms, which travel from
the atmosphere into organisms in the
Earth and then back into the atmosphere
over and over again.

Answer 19

Carbon Cycle

Question 20

4 processes of the carbon cycle

Answer 20

❑ Photosynthesis,
❑ Decomposition
❑ Respiration
❑ Combustion.

Question 21

it is the Nitrogen Cycle is a biogeochemical
process through which nitrogen is
converted into many forms, consecutively
passing from the atmosphere to the soil to
organism and back into the atmosphere.

Answer 21

Nitrogen Cycle

Question 22

6 processes of the nitrogen cycle

Answer 22

❑ Nitrogen fixation,
❑ Nitrification,
❑ Denitrification,
❑ Decay
❑ Putrefaction
