Answer:
b) fungi
Explanation:
Fungi are eukaryotes and have saprophytic mode of nutrition. They decompose dead and decaying matter and breakdown complex organic molecules to simple inorganic nutrients for consumption. Hence, they play a very important role in any food chain.
Fungi are very diverse in their morphology. They can be unicellular like yeast or multicellular and filamentous like moulds. The long branched filaments are called hyphae. Hyphae form a tangled network called as mycelium. Hyphae have a cell wall and an inner lumen. Lumen can either be septate i.e. it is divided into compartments or coenocytic i.e. protoplasm freely flows through it.

Answer: yes, many different kinds
Explanation: bacteria are everywhere and so will be found in aquaria. Aquarium health is dependent on bacteria. Fish excrete ammonia which is toxic. Bacteria such as Nitrosomonas and Nitrococcus convert ammonia to nitrite, and Nitrobacter converts nitrite to nitrate which is relatively harmless. Bacteria such as Pseudomonas stutzeri and Bacillus subtilis remove nitrate and organic waste. There are also bacteria in fish intestines, and other bacteria that can cause fish diseases or create undesirable conditions such as Pseudomonas fluorescens, Vibrio, Flexibacter or Aeromonas and anaerobes that reduce sulphates to hydrogen sulphide.
Answer;
-Special stains
Explanation;
-Cell staining is important in the diagnosis of microorganisms because bacteria can be identified by the color differentiation of stains (dyes).
-Microscopic examination of stained cell samples allows examination of the size, shape, and arrangement of organelles, as well as external appendages such as the whip-like flagella, which are the cell's organs of motion. When sample cells are stained to show their chemical composition it is called differential staining.
-Special stains are used to help visualize and/or identify structures and substances in sections.
