2. Objectives:
• Define environment
• Differentiate natural from built environment
• Define key environmental concepts
• Differentiate different types of ecosystem
3. Presentation Design
Environment
• the surroundings or conditions in which a person,
animal, or plant lives or operates (Oxford Languages)
• the natural world, as a whole or in a particular
geographical area, especially as affected by human
activity (Oxford Languages)
• encompasses all living (biotic) and non-living (abiotic)
things that live on Earth
• 2 types of environment: 1) Geographical Environment
(Natural Environment); 2) Man-made Environment
(Built Environment)
4. Presentation Design
Geographical Environment
• consists of all components provided by nature
• the physical environment as it pertains to the
physical requirements of life
• are not dependent on the existence of humans
• Sometimes, humans have no control over the
physical conditions of the environment
• also called as Natural Environment
5. Man-made Environment
• environment that has been altered by humans to
satisfy and accommodate those needs
• includes every material and non-material concept
created by man
• Will continue to exist as long as human society exist
• also called as Built Environment
7. Key ecological concepts
Organism (individual)
- an organism describes an individual
- is a single, living thing, can be a plant, animal, etc.
- capable to grow, respond to the environment and reproduce
8. Population
- term used to describe multiple individuals or organisms of a single species
that live within a particular geographic area
- group of organisms of one species that interbreed and live in the same
place at the same time
- examples:
human population, population of apple trees, pack of lions,
herd of cattle, ant colony
Key ecological concepts
9. Community
- term used to describe two or more populations of different species
- examples:
community of forest trees and undergrowth plants, birds
community, fish community
Key ecological concepts
10. Ecosystem
- is a biological environment consisting of all the living organisms or Biotic
component, in a particular area, and the non-living, or Abiotic component
such as air, soil, water and sunlight with which the organism interact.
Key ecological concepts
11. Tropical Rainforest
- are rainforests that occur in areas of tropical rainforest climate in which
there is no dry season
-all months have an average precipitation of at least 60 mm
- found in some parts of America and Africa, Southeast Asia, Australia
Types of Ecosystems
12. Types of Ecosystems
Temperate Rainforest
- are rainforests with coniferous or broadleaf forests that occur in the
temperate zone and receive heavy rain
- found in coasts of the Pacific Northwest in North America, Chile, the
United Kingdom, Norway, Japan, New Zealand, and southern Australia
14. Types of Ecosystems
Taiga (Boreal Forests)
- biome (major life zone) of vegetation
composed primarily of cone-bearing
needle-leaved or scale- leaved
evergreen trees
- found in northern circumpolar forested
regions
- characterized by long winters and
moderate to high annual precipitation
15. Types of Ecosystems
Desert Ecosystem
- the driest ecosystem of the earth
- has less vegetation and less
diversity of life
- low rainfall
- plants and animals of the desert
ecosystem have mastered the art of
survival in harsh conditions.
16. Types of Ecosystems
Grasslands
- an area where the vegetation is
dominated by grasses and other
herbaceous (non-woody) plants
- can be found in all continents
except Antarctica
17. Types of Ecosystems
Tundra
- treeless plain
-noted for its frost-molded
landscapes, extremely low
temperatures, little precipitation,
poor nutrients, and short growing
seasons
19. Types of Ecosystems
Mangroves Ecosystem
- is a shrub or tree that grows mainly in
coastal saline or brackish water
- grow in an equatorial climate,
typically along coastlines and tidal
rivers
- have special adaptations to take in
extra oxygen and to remove salt
20. Biome
- describes organisms that occupy a certain area
- determined by the primary vegetation type, climate of the area and the
geographic location
- Ex. Land Biomes (forest), Aquatic Biomes (marine and freshwater)
Key ecological concepts
21. Definition of Terms
Biosphere
- term used to describe the combination of every ecosystem on the planet
- our biosphere is the EARTH
- includes all living beings and their relationships
