-Ecology is study of interactions between non-living components in the environment
- light - water- wind- nutrients in soil- heat- solar radiation- atmosphere
What is Ecology ?
Studying of Ecology
* For non-living (abiotic)- Climatology- Hydrology- Oceanography- Physics- Chemistry- Geology- soil analysis
* For living (biotic)
- animal behavior- Taxonomy- Physiology-mathematics (population studies)
Levels of Organization of Ecology* Biosphere
– Surface of the earth – Composed of many ecosystems
* Ecosystem– Large or small as we decide.
* Population – one species live in one place at one time
* Community – All populations (diff. species) that live in a particular area.
*Habitat – physical location of community
*Organism – simplest level of organization

My insectMEALY BUG
What is Mealy Bug
- Insect in the family Pserdococcidae- Found in moist and warm climate- Pest which feed on juice of plants- Adult is about 2-5mm long- 12-15 Generation per year
Life Cycle- Reproduction in mealy bug is mostly parthenogenetic.
- Mature female lays eggs in ovisacs
- Each ovisac contains 150- 600 eggs, majority of which are female.
- Eggs hatch in 3 to 9 days into nymphs called ‘crawlers’, which are very mobile
- Individual mealy bug take 25- 30 days to grow into adults under normal conditions.
- There are 12- 15 generations in a year.
- The insect remain active and reproduce round the year in warm climate
Life Cycle
of Mealy Bug
How they move ?- They crawl from an infected to healthy plant.
- Small crawlers are transported by wind, rain, birds and clothing.
- The waxy helps by sticking/clinging to equipments, animals or people moving during field operations.
- Transport of infested cotton sticks or seed cotton for long distance
- Crawlers are also carried through irrigated water
Mealy Bug and Ants
- Mealy Bug provide surgary secretion (honeydew) for ants as food.
- Ants helps to spread mealy bug in return
- Ants keep mealy bug colony clean from detritus
Damage-Weaken the plant by sucking sap from leaves, stems, roots and fruiting bodies
My plantMOSS
What is Moss ?
- Flowerless- Spore-producing plant- Moss stems are fairly weak- All mosses have rhizoids

FEEL
- Hot weather but cool at the river- Water very cool- Relaxed- Humid- Feel like want to go home

SMELL
- Smells salty at the stream- Smell of the leaves- Smell of the nature, the environment
TASTE
-The leaf tastes bitter- Water tastes like mineral water- sand tastes bitter
What I’ve experienced and learnt after the trip- Appreciate whatever we have now- Don’t destroy the nature, don’t throw rubbish
anywhere- To read the brief first before any project- Save endangered species- Do not waste food, water and electricity - Do not pollute the wonderful air
What I’ve learnt after the presentation- Work by following the brief- Make a proper plan before the presentation- Time management- As a leader, I’ve experienced and learnt the role of
leading the team and also my responsibility- Work well as a team, one man cannot do a good
job- Learnt to accept others ideas and combine- Reduce colours in info graphic, don’t make it
messy but simple
