Geography paper 3

Question 1

What is a biome

Answer 1

Biomes are areas of the planet with similar climates, landscapes, animals and plants.

Question 2

What factors effect what lives in each biome

Answer 2

how warm or cold it is
how dry or wet it is
how fertile the soil is

Question 3

What are the 7 different types of biomes

Answer 3

Rainforests
Deserts
Savannah
Woodlands
Grasslands
Tundra
Taiga (coniferous/boreal forest)

Question 4

Conditions of tropical rainforests

Answer 4

Tropical rainforests are hot and wet all year round.
They are home to half of all the different types of plants and animals on the planet.

Question 5

Conditions of deserts

Answer 5

Deserts are dry all year round.
Only a few plants might grow, such as small shrubs or cacti, because the soil is shallow and rocky. Animals come out at dusk when it is cooler.

Question 6

Conditions of savannahs

Answer 6

The savannah is hot all year round with a long, dry season.
Only grasses and shrubs grow here. It is home to lots of different types of animals such as elephants, zebras and wildebeest.

Question 7

Conditions of woodlands

Answer 7

Woodlands are habitats where the main plants found are trees, but mosses, ferns and lichen can also be found.
The climate is warm and mild, with more rain falling in the winter than in the summer.

Question 8

Conditions of grasslands

Answer 8

Grasslands are areas of land that are vast and open. Grasses are the main plants.
The largest grasslands are found in East Africa. Zebras, giraffes, elephants and rhinos all live in grasslands.

Question 9

Conditions of tundras

Answer 9

The tundra is the coldest of all the biomes. There is very little rain or snow and the temperatures are freezing. Winters are long and summers are short. Part of the soil is frozen all year round, although the top part defrosts in summer and plants such as mosses can grow.

Question 10

What are lianas

Answer 10

Lianas that use the tree to climb up to the sunlight in the
canopy

Question 11

Why is the nutrient cycle rapid in a rainforest

Answer 11

• a large biomass store (dense vegetation)
• a small litter store (rapid decay)
• a large take-up of nutrients (rapid plant growth)
• a larger supply of nutrients (weathering)
• a larger loss of nutrient (throughflow).
