Bacteria and Fungi are the two primary decomposers
Explanation:
<u>Bacteria: </u>Bacteria are known as microscopic single celled organism. Their existence is between inside as well as outside the organism. The use of bacteria is in medical and industrial processes. They are first organisms in earth. Bacteria can survive in worst condition. There are huge number of bacteria. So, it is classified according to their structure and shape.
The life cycle of bacteria can be divided into log phase, lag phase, the stationary phase and Death phase. In lag phase bacteria don’t grow they produce amino acid and protein and make copies of DNA. They make themselves ready for division. In log phase bacteria rapidly multiply itself through binary fusion. In the stationary phase the growth of bacteria is dwindles because of lack of space and accumulating waste. The last phase is death phase where bacteria loss its ability of reproduction.
<u>Fungi:</u> Fungi is same like bacteria play vital role in ecosystem. They are also decomposer. The first way of fungi life cycle is based on spore phase. They begin with haploid. They have one copy of all their genetic material. The second stage is mycelium stage where fungi reproduce asexually.
A mold was developing in some of the culture dishes used by Sir Alexander Fleming and was eliminating some of the bacterial population. The hypothesis is that the mold was generating a chemical, which was toxic to the bacteria in the dishes and killed them.
The hypothesis was examined by separating the Penicillium and administering it into the solution of nutrient broth. After the growth of Penicillium it was withdrawn from the broth. The broth was then eventually supplemented to the bacteria and the bacteria died. Thus, it can be concluded that the hypothesis is supported.
Answer:
nitrogen fixation is the answer
