Answer:
The organisms in that habitat including the extreme bacteria, will gradually decline
Explanation:
According to the question, an extreme bacteria lives and thrives in an hydrothermal vent where extremely hot water, methane gas, and sulfur are released. The hydrothermal vent located deep in the ocean is the habitat of the bacteria, and considering the fact that it thrives there means it is better adapted to do well in such extreme environment using the sulfur and methane gas produced by the vent for its development.
If the hydrothermal vent becomes inactive i.e. no production of sulfur and methane, and cold, the extreme bacteria might not survive as the conditions required for its optimal functioning are no longer met. The bacteria also makes up the base of the food web in that habitat (constituting organisms like mussels, tube works), meaning that, it begins the feeding chain in that habitat. Hence, a decline in the number of the bacteria will result in a decline in the number of other organisms dependent on the bacteria as energy source (food).
Answer:
Photosynthetic: a portion of the microscopic organisms are photosynthetic in nature they can utilize carbon dioxide and daylight for the development of nourishment. Model: cyanobacteria or blue green growth.
Other microscopic organisms are heterotrophic in nature they are not ready to incorporate nourishment without anyone else and relies on living and nonliving material for their supplements. Model pseudomonas, staphylococcus. These are chemotrophic, organ trophic and so forth.
Archaea: it is a gathering of archaea which are considered as associating join among eukaryote and prokaryote. Archaea are considered as archaebacterial yet don't have a place with the gathering of Bacteria. They have unmistakable highlights then microscopic organisms that is the reason they set in various gathering. A large portion of the archaebacterial are extremophiles and they don't present in ordinary condition where typical microscopic organisms are available. Because of their territory they have diverse basic and practical properties.
Pathogenic: a portion of the gathering of Bacteria are pathogenic in nature implies they can make malady any host. Pathogenic microscopic organisms are unique in relation to nonpathogenic microbes in auxiliary design and utilitarian properties. They have wide scope of host from plant and creatures. Pathogenic microbe’s displays polysaccharide covering, poisons, containers, discharges, compounds and so on. These all things give them pathogenic properties.
Gram negative: Gram recoloring is a strategy for recoloring the phone mass of microorganisms by which we can recognize gram positive and Gram Negative microbes. It is given by researcher Christian Graham in which we use Crystal Violet to recognize Gram Positive Bacteria. Gram Negative microbes don't take-up Crystal Violet and they are recolored by counterstain safranin.
Answer:
B. Reproductive cells
Explanation:
Meiosis is a reduction cell division that is observed in germ cells or reproductive cells.
