Read and analyze the Ecosystem Response section and list the negative feedback mechanisms that keep the bay ecosystem above its steady state.
Answers
Answer:
Increase occurs in fresh water input.
Decrease occurs in the salinity of the bay.
Explanation:
The low rate of fresh water input and the presence of high amount of salts in water decreases the population of producers such as grasses in bay ecosystem. Due to this decrease, the population of the marine animals decreases due to the low availability of food for herbivorous organism that lives in the bay. The negative feedback mechanisms will be achieved if increase occurs in fresh water input and decrease occurs in the salinity of the bay.

Answer:
Liver or fat cells
Explanation:
The triglycerides plays important role in providing energy and they are the kind of fats that are energy rich. The triglycerides are made of three fatty acid chains and a molecule of glycerol.
The increased amount of triglycerides stores in liver or fat cells. This stored form is used further to provide energy when required. This natural process helps the body during fasting and maintains energy requirements of the body. The hormone glucagon is responsible to use triglycerides.
Answer:
Triglycerides are made up of one molecule of glycerol attached to the three fatty acid chains. In body majority of triglycerides are stored in liver or fat cells. Glucagon is the hormone that is responsible for the storage of triglycerides in liver or fat cells.
Stored triglycerides act as the reserved energy resource which is used when the glucose and glycogen is depleted in the body which are primary energy resources for the body.
To release triglyceride lipase breaks the triglycerides and release the fatty acids in the blood which is used to provide energy to the body.

Water exists in all the statesofmatter which are the solid, liquid, and gaseous states.
What are the states of water?
Water is known to exist in three different physicalstates. These are the solid state as ice, the liquid state as water itself, and the gaseous state as water vapors.
Under the conditions of standard temperature and pressure, the freezing point of water is zero degrees Celsius. At this temperature, water starts to freeze and attains a solid form which is in the form of ice. The density of ice is lower than the density of water because of the fixed intermolecular distances in ice.
Under the conditions of standard pressure and temperature, water exists in liquid form between temperature ranges of zero to a hundred degrees Celsius. Liquidwater is essential for all organisms. It functions as a universal solvent.
At a temperature above hundred degrees Celsius, the intermolecular integrity between the molecules of water starts to decrease and ultimately breaks completely. In these conditions, the water turns into vapors.
Therefore, water exists in all the states of matter which are solid, liquid, and gaseous states.
