Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bacteria and fungi typically serve what role in an ecosystem?
A
herbivore
B
carnivore
C
omnivore
D
decomposer
Explanation: 

Detailed explanation-1: -Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.

Detailed explanation-2: -Fungi and bacteria are essential to many basic ecosystem processes. Some types of fungi and bacteria can break down fallen wood and litter returning nutrients to the soil. Other types can fix nitrogen in the soil and help plants get nutrients from the soil.

Detailed explanation-3: -Fungi decompose organic matter by releasing enzymes to break down the decaying material, after which they absorb the nutrients in the decaying material. Hyphae are used to break down matter and absorb nutrients and are also used in reproduction.

Detailed explanation-4: -Together with bacteria, fungi are responsible for breaking down organic matter and releasing carbon, oxygen, nitrogen, and phosphorus into the soil and the atmosphere. Fungi are essential to many household and industrial processes, notably the making of bread, wine, beer, and certain cheeses.

Detailed explanation-5: -Bacteria play an important role in decomposition of organic materials, especially in the early stages of decomposition when moisture levels are high. In the later stages of decomposition, fungi tend to dominate. Bacillus subtilis and Pseudomonas fluorescens are examples of decomposer bacteria.
