Geography Ecology essay

What biome did u study

tropical rainfotest biome

where is the biome found

In the tropics between 23 degress north and south of equator

largest tropical rainforest is?

amazon basin south america

4 aspects i will disscus in answer

1.Key characteristes of climate in a tropical rainforest biome.

2.Soil types and their characteristics in a tropical rainforest biome.

3.Flora and their characteristics in a tropical rainforist biome.

4.Fauna ant their characteristics in a tropical rainforist biome.

what climate does it have?

tropicol climate that is wet and humid all year round.

average temp

27 degrees per annum

annual temp range?

2 degrees (very small)

does the amazon have sesonal change

No

daytime temp

No more then 35 degrees

why is high temp caused

angle of sun (concentrated small area)

humidity percent

77

cause of humidity

intense rainfall, evaperation, transpiration.

rainfall frequnce in amazon

200 per year

rainfall amount in amazon

2000mm each year

the NE and SE trade winds create

low pressure belt(due to them meating at equater and rising up)

suns heat causes what?

moustire in air to rise and form convectinol thunderstorms.

conlusion for climate

The tropical climate is responsible for a great variety of living things in the forest.

As a result the climate has led to the high biodiversity in the tropical rainforest biome.

soil type in tropical rainforest biome

Latosols(tropical red soils)

how is the tropical red soil formed

rapid deep chemical weathering and leaching

hot humid conditions and chemical weathering has lead to

deep soils forming

soil dept in some areas

up to 30m deep

latosal soil is

very poor in nutients and infertile

why was leaching caused

1000s of years of heavy rain

rainwater washs nutrients away from?

A horizon to B/C horizon beyond most plant roots.

what builds up in the soil due to leaching

Iron oxide and aluminuim oxide due to it not being leached away.

what gives the soil its colour

Iron oxide and aluminuim oxide

can the soil support wide diversity of vegitation

yes

the diversity of vegitation due to

large amount of humus

quick recycling of plant litter means

short nutrient cycle

what thrives?

bacreia and fungi and quikly breakdown organic matter to humus

if vegitation is removed

hummus supply is gone and leads to infertial soil

lack of vegitation exposes the soil to

heat causing the soil to break down to laterite

soil conclussion

Climate and soils have affected the vegitation types in tropical rainforest biome.

the natrual vegitation of the amazon is

rainforest or jungle

The _____ of the amazon is great for plant growth

climate

why is the climate ideal for flora

rainfall humidity high temp

what biome has the largest biodiversity

Rainforest

example of trees growing there

mahogany, teak, palm oil, brazil nut

to avoid compition (sunlight mousture nutrients) what system devolped

4 layerd system

structure layers

1.the emergent layer

2.the canopy layer

3.the understory layer

4.forest floor layer

Emergent layer(tops of trees)

40m to 80m, only sprout leaves at 30m due to compition for light

canopy layer

20m-40m, plants in the canopy include vines,mosses and lichends

the understory layer

15m-30m, dark litlle plant growth

forest floor layer

0m-5m, very dark , little growth unless clearing appers.

percent of sunlight reaching forest floor layer

1-3 percent

flora conclusion

climate,soil type and vegitation affect fauna of a tropical rainforest biome.
