CONTAMINATION
EFFECT
ON A FOOD CHAIN
An ecosystem is a self-contained, dynamic system made of a
population of species in its physical environment. This concept is used to
study the complex interactions between the organisms - plants, animals,
bacteria, and fungi - that make up the community. There are many
different ways in which the community of organisms interacts.
There is the food chain where each organism is in a producer,
consumer, predator, and prey relationship; there is the oxygen cycle
and the water cycle that sustains the organisms. When an ecosystem
gets polluted, the natural balance in the system is disturbed and this
affects the organisms in different ways. It is important to know how a
simple act like introducing sewage water or toxic waste into a lake can
threaten several life species and plants in the area.

STUDY OF THE EFFECT OF CONTAMINATION ON A FOOD CHAIN
Pollution and the ecosystem
Pollutants like oil, detergents, nitrogen and phosphate from fertilizers and lead can have a huge impact on
the ecosystem, most if the water gets polluted. In a lake, for example, it can wreak havoc on the ecological
balance by stimulating plant growth and causing the death of fish due to suffocation resulting from lack of
oxygen. The oxygen cycle will stop, and the polluted water will also affect the animals dependant on the
lake water.
Saving the planet. That’s our day job. And it could be yours too.
People from all corners of the globe are helping WWF to build a future
where humans live in harmony with nature. They might be tracking
tigers in the Himalayas or holding briefings in Brussels, helping
communities in the Congo Basin develop sustainable livelihoods or
helping multinationals develop sustainable supply chains.
At WWF we are passionate about finding the right person for the job,
every time. Selection is based on merit, skills, relevant experience,
qualifications, culture fit and alignment to our values.
We need knowledgeable, talented people who’re passionate about
engaging and inspiring others. People who share our optimism that it’s
possible to change the world. People who’re determined to make a
difference.
Are you one of those people? Then we’d love you to join us
