Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In an ecosystem, a sudden decrease in the number of natural bacteria in the soil will most likely result in:
A
increased water pollution in the soil
B
increased precipitation and flooding of the soil
C
a reduction in the amount of nitrogen available to the ecosystem
D
a decrease in the number of fossils formed in the soil
Explanation: 

Detailed explanation-1: -Organisms are unable to grow in the absence of nitrogen fixation. Plants that are deficient in nitrogen appear pale or yellowish. They produce quite fewer flowers & fruits than other plants. The majority of plants will also not be able to directly consume nitrogen from the environment.

Detailed explanation-2: -But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits.

Detailed explanation-3: -Denitrification. Denitrification is the biological process in which nitrate is converted to atmospheric N2. It is one source of N loss from the soil. Like other N processes, denitrification is a biological process that is mediated by denitrifying bacteria.
