Answer from: bighomie28

Option C) water

Explanation:

The factors affecting the distribution of organisms in aquatic biomes include:

- Light penetration: Plants life is limited to the upper layers of the ocean where light cab penetrate and be used to produce food. Thus, very few organisms are found in the ocean deep.

- Waves: the movement of surface water of the oceans, and it's direction affect the placement of organisms as they must have strong anchor or body parts suited for buoyancy

- salinity: not all organisms can survive in water with high salt content. Thus, some live in salty water, and others in fresh water or the mixture.

- Mineral content: the levels of hydrogen ion could make a water bidy alkaline or acidic thus affecting organism that can survive in it

Thus, since water ordinarilly is Universal, it is not an important factor in determining distribution of organisms in aquatic biomes

Answer from: brittanyfox411

Water

Explanation:

Aquatic ecosystem is water ecosystem. Its a body of water serving as an habitat for organism. Water is a constant as it is the basic of distribution.

All the other factors are important in distribution of Organism in aquatic ecosystem.

1.light penetration - light is important in stratification of organism in both marine and fresh water habitat Some organism in the aquatic environment photosynthesis and they require light in producing their food. Hence light is important

2.Mineral concentration and nutrients- Algea are importance microgransim in aquatic habitat as the serve as food for some other organism. Places with low concentration of nutrients especially nitrogen and phosphorus reduces the existence of algae.

3.Salinity- The level of tolerance of salt differs in aquatic organism. Fresh water organism cannot torelate as much salt as marine habits organisms. Hence salinity is important

4. Waves and ocean current also affect the distribution of acquatic organism. The current is some large oceans cant be compared to lake and some streams and the survival of organism is also dependent on it.

(see chapters 3 and 4, infection and passive immunity.) 2. explain how acute necrotizing fasciitis developed in this case and the pathophysiology involved. (see acute necrotizing fasciitis.) 3. what is the potential outcome for ms. w if antibiotic drugs do not reduce the infection quickly?
