The right options are;
1. amount of nitrogen, oxygen, and other elements dissolved in water.
2.wetlands.
The nutrient availability of aquatic ecosystems is the amount of nitrogen, oxygen, and other elements dissolved in the water.
Nutrients are chemical elements, and sources of nourishment that are important to the development of plant and animal life. In healthy aquatic ecosystems such as rivers, nutrients are required for the growth of the organisms in the entire aquatic ecosystem. The most common nutrients in aquatic ecosystems include oxygen, nitrogen, and phosphorus.
A wetland is an ecosystem that is covered by shallow water, either periodically or permanently. Wetlands usually emerge from underground sources in mountains or hills.
Explanation:
A wetland is a biome which has both water and land that are intermixed in various ways. According to the type of the wetland, the ecosystem differs.
Bogs: Wetland with water from precipitation and no inflow or outflow of surface or ground water.
Soil: Acidic, infertile with less nutrient content
Vegetation: Acid-loving plants
Swamps: Forest wetlands near rivers and lakes.
Soil: well draining, mineral soil
Vegetation: Trees and bushes. Swamps are classified according to the vegetation, like coniferous swamp, hardwood swamp, shrub swamp etc
Marsh: Wetlands mostly inundated with water leading to waterlogged soil
Soil: Organic and mineral soil
Vegetation: Hydrophytic plants adapted to waterlogged soil
Estuaries: Wetland regions enclosed by land one side where fresh water mixes with saline ocean water.
Soil: Saline alkaline soil
Vegetation: Mangrove trees
Rivers and lakes are water bodies that form a part of wetlands.
Rivers are flowing water bodies which flows through water current and picks up sediments as it flows.
Lakes are stationary water bodies that are enclosed by land mass on all its sides.
The wetlands act as a natural filter and receive all the sediments, pollutants etc which are dissolved in water and carried by the rivers and other water sources.

No significant difference between mean and Expected value
Step-by-step explanation:
Hypothesis
H0 : u = 77.5
H1: u is not equal to 77.5
Alpha = 0.05
Mean = Σxi/n
= 77.09+75.37+72.42+76.84+77.84, +76.69+78.03+74.96+77.54+76.09+81.12+75.75/12
= 919.74/12
= 76.645
We get the variance s² = xi² -n(barx)²/n-1
= 77.09²+75.37²...75.75²-12(76.645)²/11
When we solve this out
We get 4.3486818182
T test = barx - u/(s/√n)
= (76.645-77.5)/√4.3486818182/12
= -1.420293
T critical = Tn-1, alpha/2
= 2.200985
The test statistic is less than 2.201 so we accept the null hypothesis at 0.05 level of significance. And then conclude that there is No significant difference between mean and Expected value.
a. both support a large number of plants and animals adapted for aquatic living
Explanation:
The freshwater and the marine ecosystem are home to a large number of fora fauna and consist of diverse species that feed and survive on the characteristic of its water bodies. Some need saline while others need freshwater systems. Global warming hazardous to both and thus both of these water systems are in constant change.No significant difference between mean and Expected value
