The Environment
1.
2.
3.
4. Class Discussion
• What type of environment did you
see?
• How about the climate/temperatures?
• Can food be found easily?
• Where the animals/plants dependant
on each other?
• What were some of the concerns
faced for survival?
5. Tropical
Park
Field Rivers Savannah Ocean
Garden Coral Reefs
Temperate
Mangrove Desert Tundra
Rainforest
Ocean
6. Different types of
Habitats/Biomes
• Where can you find these habitats?
• Explain the difference between these habitats.
– Types of animals
– Climate / Temperature
– Plants / Trees
• What are some of the concerns faced for
animal survival?
• Which do you think will support the greatest
diversity of living things? Why?
7. • Online reflection for the different types of
biomes:
• (refer to questions on the previous slide)

biomes visit here:

8. • Temperature
Abiotic • Air
• Water
(Physical)
• Other living Biotic
• Sunlight
organisms
• Soil (Living)
9. • The measure of how hot or cold is the
environment
• Affects the
– Activities of organism
• Active? Less active?
– Types of organisms living there
• Warm-blooded? Cold-blooded?
• Most organisms cannot survive under extreme
temperature
10.
11. • Needed by all livings things
– Oxygen Respiration by both animals and plants
– Carbon Dioxide Plants to carry out photosynthesis
• Amount of air varies from place to place
– Mountains – less O2 and CO2 in the air, less organisms
are suited for survival there
• Quality of air differs in different environment
– City area pollution, affects living things
12.
13. • Sun is Earth’s main source of light
• Plants need light energy to make food
– Photosynthesis
• Influences growth changes in plants
– Flowering and germination
• Amount of light influences type of plants found
in a particular habitat
• Light influences animals too
– Nocturnal / Diurnal animals
14.
15. • All living things need water for survival & carry
out life process:
– Source of food fish
– Reproduction frogs, lay eggs in water.
• Amount of water in the environment
influenced by:
– Amt of rainfall
– Presence of lakes, rivers & streams
• Determines the type of organisms that can live there
• Environments with a lot of rain can support a
greater diversity of living things.
16.
17. • Soil consists of:
– organic materials like:
• dead and decaying organisms
– Inorganic materials
• Minerals, water and trapped air
• Composition of soil affects the type of
organisms that can live there:
– Some plants and burrowing animals may find it
unfavourable to live in soil that is:
• very wet
• has few air spaces.
18.
19. • Every organism plays a role in the ecosystem
• Organisms interact in many ways:
– Use one another as food (Food Chain)
– For shelter
– Seed dispersal
