FaunaEcosystem Flora BiomeEquatorial region

A large ecosystem

Area around the equator where rainforests are located

Animals in the rainforest

A community made up of living organisms (plants/animals). E.G. rainforest or a desert.

Plants in the rainforestSlide2

How are plants adapted to the TRF?

Lesson Objective:- To investigate the challenges faced by plants living in a tropical rainforest and the creative solutions they develop to overcome these challenges.Lesson OutcomeBy the end of today’s lesson you will be able to:-To be able to describe and explain the nutrient cycleTo know what adaption meansTo describe and explain how plants (flora) adapt to the rainforest.

Lesson 6Slide3

The Nutrient Cycle

Draw this diagram into your booksSlide4

Dead leaves and animal waste fall out all year round.

The decomposers release the nutrients from them.The soil underground is poor because the nutrients do not get a chance to sink in.

The roots quickly take up the nutrients again.

The nutrients help the vegetation grow.

Using the information complete the diagram

Decomposer – Bacteria or a worm that breaks down dead leaves for nutrientsSlide5

Types of leaves in the rainforest

Drip tip leaves allow the rain to drip off themThick waxy coated leaves protects against rain and insects

Sharp edges prevent (stops) animals from eating them

Larger leaves grow in the shrub layer. This is to trap as much light as possibleSlide9

Group rotation

Your group will have 5 minutes with each learning mat - it is your responsibility to find out the details before the mat is passed on!Slide10

Plants of the Rainforest

More than 2/3rds of the worlds plant species are found in tropical rainforests. Due to the amount of competition for light and food plants have evolved and adapted to allow them to survive in the rainforest.EpiphytesEpiphytes, or air plants, have adapted to grow on the branches

, trunks, and even the leaves of trees.

They feed on the rain and nutrients from rotting leaves. There is too much competition for light and nutrients in the shrub layer.

Buttress Roots

Most

rainforest soil is very poor with all the nutrients available largely remaining at surface level. Because of this rainforest trees have very shallow roots.

Some very tall trees

have formed buttress roots

, which grow out from the base of the trunk

(sometimes

as high as 15 ft above the

ground).

These extended roots

spread out and increase

the area over which nutrients can be absorbed from the

soil.

Different types of epiphytes may grow on the same tree. They begin their life in the canopy from seeds or spores transported there by birds or winds.Slide16

Plants of the Rainforest

LianasLianas have thick, woody stems. They begin life on the forest floor and depend on trees for support for survival. They attaching themselves to trees with sucker roots and grow upwards with a younger tree. They also climb towards the sunlight by winding themselves round the tree's trunk

.

When they reach the top of the canopy they often spread

to

wrap

around

other lianas. This network of vines gives support against strong winds to the shallow-rooted, top-heavy trees.

Strangler Fig

The

seed of the strangler fig starts life as an epiphyte high in the

trees. It is transported here by birds

and monkeys which eat the fig fruit. The seedling fig sends down long roots to the ground from where it begins to surround the host tree. It grows quickly and eventually suffocates the host: when the host tree dies it leaves an enormous upright strangler with a hollow core.

By using an adult tree as its host, the strangler fig avoids competition for light and nutrients at ground

level.Slide17

Plants of the Rainforest

BromeliadsBromeliads are related to the pineapple family. Their thick, waxy leaves form a bowl shape in the centre for catching rainwater. Some bromeliads can hold several gallons of water and are miniature ecosystems in themselves providing homes for several creatures including frogs and their tadpoles, salamanders, snails, beetles and mosquito larvae. Those that die decompose and furnish the plant with nutrients. This means that they don’t need to compete against other plants, as much for, water, sunlight and nutrients.

Saprophytes

Saprophytes act

as the rainforests

decomposers, they are very small and work very fast to compete against the heavy

rainfall which constantly washes away nutrients on the forest floors

.

Decomposers work

in the warmth and wetness and can

often break down dead animals and vegetation within 24 hours

.

Decayed

matter contains essential nutrients like iron, calcium, potassium and phosphorous all of which are

necessary to promote healthy rainforest growth. Without them the trees would not receive enough nutrients.Slide18
