1

Definition of Ecology and Ecosystem

Study about the relationship between living things & environment including physical and biological environment.

2

Relationship of ecosystem with human

Human is affected by:
1. climate and biological environment
2. bio factors
3. Culture and traditions
4. infrastructure
5. physical factors

3

Environmental factors
(Controller of organism in specific environment)

1. climate
2. topography
3. human
4. soil
5. vegetation

4

Important terms

Species, population, biotic community, ecosystem, biome, biosphere

5

Ecosystem

The unit of land that compose the society of living things and environment that has the duty together

6

Types of Ecosystem

Aquatic
Terrestrial

7

Aquatic Ecosystem

Marine, Brackish, Fresh water

8

Terrestrial Ecosystem

Forest, Agriculture, Grass land, urban, others

9

Ecotone

The ecosystem between land and aquatic ecosystem, that has abundance number of edge species

10

The Structure of Ecosystem

Abiotic
Biotic

11

Abiotic Structure

The activator or stimulator

12

Biotic

The doer, doing activities

Producers
Consumer 1, 2, ...
Decomposer

13

The food chain in ecosystem

Producer > Consumer 1 > consumer 2 > Decomposer > Producer&supporter, Supporter > producers

Supporter : climate, rainfall, humidity

14

Tropic Structure

Piramid

15

The cycling of Matters in Ecosystem

Biosphere: N,P, C
Advantage: prevent the accumulation of waste, ecosystem won't run out essential elements.

16

Energy Flow in Ecosystem

Using Thermodynamics Law 1 & 2

17

The Law of Thermodynamics 1

Energy can't be destroyed and can't be made.

18

The Law of Thermodynamics 2

The process of transferring energy will be followed by the lose of energy

19

Sir Eltonion Pyramid

Piramida tegak: sustainable

Piramida terbalik: Unsustainable

20

Sustainability of Ecosystem

1. Consider from balance of nutrition cycling

input > system > output , input = output

2. Consider from structure of energy flow
(piramid tegak)

21

Balancing Ecosystem

Self maintenance + Self regulation = Homeostasis
