Ecosystems and biomes

By the end of the lesson you will;

1)Be able to define ecosystems

2)Be able to define and locate a range of biomes around the world

3)Be able to explained the key characteristics of Rainforest and deciduous forests

4)Have explained some of the key processes involved in rainforests

5)Have applied your new knowledge

So what is an ecosystem? Ecosystems are a community of plants and animals and the

environment in which they live.

They contain living (biotic) and non living (abiotic) parts.

Biotic features are living things

Abiotic features are non living

Task; On your tables come up with 5 Biotic and 5 abiotic factors.

Biotic Factors

Abiotic Factors

Food chains;

TaskRead through the following stages of a food chain Make your own food chain for an area in the Uk

Biomes

A biome is a major regional group of distinctive plant and animal communities.

It is classed as a global scale ecosystem Best adapted to the region's physical natural

environment, latitude, altitude and terrain factors. This would explain why cacti only grow in the

desert and why some species exist in very cold environments.

What Biomes exist around the world?

Where are the different Biomes in the world?

Task 1; Stick the map into your books

Describe the location of 4 different biomes around the world

Key words;

Describing different Ecosystems; TASK1.Each of you have a different type of ecosystem

2.You need to make notes on the ecosystem

3.You need to be ready to someone else in the class

TaskWhich of the different ecosystems has the best conditions for life?

Key Questions; 1.Where is the ecosystem? 2.What are the key characteristics? (Temp and rainfall) 3.How does this impact on plant and animal life? 4.Why is this ecosystem located in this area?

Key Ecosystems;

Deciduous Forest Tropical Rainforest

The water-cycle in the RainforestTask 1

1.Read through the following statements

2.Put them in the correct order to explain the water cycle

3.Draw a daigram to show the key processes The morning sun heats the ground

There is a large amount of water vapor in the air

The warm air starts to rise as a bubble of water vapor

The clouds continue to develop to a height of between 2500 and 3500m

This will in turn heat the air around it

The warm air is fed by more warm air called thermals

This means that condensation will occur at a low level

Eventually there is too much water in the clouds leading to rain

This means that clouds will be formed between 600m and 800m

If the warm air is forced to rise over a mountain, warm moist air condenses to form cloud forests

Key Question; Which of the following will happen during the morning?

Key Question; Which of the following will happen in the afternoon?

Water movement in forests;

The canopy of the rainforest catches the rain (interception)

Rain hitting the ground will cause soil erosion

Some water is run down the step – stem flow

Leaf drip will reduce the amount of soil erosion in the rainforest

Water that is on the leaves may be evaporated

Drips from the leaf are called leaf drop

The roots of the trees are shallow

The roots take in water and nutrients

Stem flow Leaf drip

Evaporation from the soil

Water is lost through pores in the leaf called transpiration

Interception storage Evapotranspiration

Precipitation Surface storage in puddles

Task1.Add labels in to the correct section of the tree2.Explain how water moves in the rainforest

Ecosystems and biomes

By the end of the lesson you will;

1)Be able to define ecosystems

2)Be able to define and locate a range of biomes around the world

3)Be able to explained the key characteristics of Rainforest and deciduous forests

4)Have explained some of the key processes involved in rainforests

5)Have applied your new knowledge

Applying your new knowledgeTaskYou are going to work in a group of 3 You need to try and get through as many questions as possibleChoose how many points you wantYou have 5 minutes to answer as many questions as possible Good luck Points

1. Name 3 decomposers in a food chain

What is drip flow?

2. Explain one path that rain can travel as it arrives on a tree

What type of rainfall do we get in Rainforests?

3. Where do we find rainforests? And explain why the climate is like this

Why do you get deserts at 30 degrees north?

4 Describe and explain 3 different methods to reduce the impacts of low pressure systems

Describe and explain 3 different ways that high pressure systems can be reduced

5. Explain the impacts of a low pressure system on different groups of people (at least 3)

Why do you think that tropical rainforest are in danger of being destroyed
