The QuestionOn 23 May 2013, we went for a Science Enrichment Program, taking down photos and notes along the way.We were also given the question

“HOW DO WE KEEP A BALANCE BETWEEN URBAN AND NATURAL ENVIRONMENT?”

The AnswerNatural environment needs to be cleared for urbanization (building of MRT rails, HDB flats, etc.)Yet we need to save natural environment to save the Earth (Plants produce oxygen)The Solution:

As our Government (URA) plans for roads, houses, etc., they need to conserve some of the natural environment in Singapore.

TASKWe were asked to identify the three features of the eco-system and describe how they aid in the survival of specific organisms.So several unique organisms seen during the activity will be listed down.

1. Strangling figsTakes a long time to germinateStrangles a host tree to get its nutrients while climbing to receive sunlight

What’s this?

2. Golden Backside Ant

3. Crab spiderArranges legs in claw like formationHides under leaves and in flowersEats small insectsGreen in colour

What helps them survive in their ecosystem?

Abundance of natural fruit (food)Variety of preyNo human predators and no accidental introduction of foreign speciesA lot of pollinators

Threats Increase in carbon emissionsClearing of natural environment for urbanization

How to deal with threatsTo reduce carbon emission:Use fan instead of of air- conditioner (air-con gives out carbon dioxide and uses electricity)Use public transport (so as to reduce number of cars on roads because the cars produce carbon emissions) or use alternative methods to travel, eg. bicycle or walkingTry to prevent the clearing of natural environment or use alternative ways so that the extent of damage to the natural environment will be decreasedSupporting groups wanting to save natural environments, eg.
