Explanation:
Scientific theory is based on complex observation, inference and experimentation techniques. Usually, the resulting reports are checked and peer-reviewed thoroughly before being accepted as explanations for facts evidence.
Thus, theories are rigorously tested, and verifiable explanations for facts which are based on observations.
Any non-living factor that is used or present in an ecosystem
Common ones are sunlight oxygen nitrogen climate temperature pH levels and water
Answer:
I think True
Explanation:
You can refer to it for more information:
The coastal ocean zone and estuaries are alike in that both are important as breeding and nesting areas for birds. The depth of the water in an aquatic ecosystem determines the amount of sunlight that living things receive there. ... The water in freshwater wetlands is always brackish
Carbon comes from blackened marshmallow or egg-shells, newspapers which contain cellulose, and sulphur source, for example, calcium sulphate in winogradsky column.
Carbon is important because it promotes the growth of different microorganisms. For example chlorobium, chromatium, rhodomicrobium, and Beggiatoa.
Hydrogen sulphide gradient is generated from bottom to the top in a winogradsky column because they dominate the zone with sulphur which reduces bacteria.
Photosynthesis is different between cyanobacteria and green and purple sulphur which is sulphur anaerobic bacteria being the top layer of aerobic bacteria which produces carbon dioxide which feeds back into the column by creating another reaction.
