Can you think of a real-life example of how man-made pollution affected a real ecosystem, its abiotics (e. g. temperature, water quality, etc.) its biotics (e. g., species extinction), or its habitat?

Nigeria Niger Delta Community

Explanation:

Human activities in the form of man-made pollution has had an almost irreparable condition to the ecosystem, abiotics, biotics and habitat of the Niger delta region of Nigeria, West Africa.

These activities has brought an end to the rich fish species in this region, it has destroyed completely the marine life. Some species of birds are no more. Obviously, the soil is destroyed, it's micro organism and nutrients levels are all gone.

Some of such activities that has led to this destructive situation includes:

1.  Natural Gas Flaring

2. Depletion of Aquatic stability

3. Oil Spillage

4. Destruction of Mangrove forest etc.

1) Toxic gases released from the exhaust of cars into the atmosphere can pollute the environment and habitat.

2) Improper disposal of waste or sewage, which ends up in the soil, streams or rivers where human get drinking water and it can even pollute the atmosphere too.

3) Spillage of oil which can enter the rivers

4) Burning of clothes, tires and other materials that release black smoke, carbon monoxide and other harmful gases.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
