Answer:
Changes in the basal levels that are on the bottom of the food chain.
Explanation:
Trophic levels are represented by steps in the food chain. In a simplified diagram, the first basal level is represented by primary producer organisms that include plants and algae. The herbivores are localized in the second place, while in the final levels it is possible to find carnivores and predatory species. It is well known that the changes in the basal trophic levels of this chain (i.e., changes in the first and the second levels) may alter the equilibrium of the food chain and consequently have effects on the stability of the ecosystem.
The level of organization that includes all the other levels of organization is the organism level.
Further Explanation:
The human body is organized at different levels, beginning with the cell followed by tissue, organ, organ system and finally the complete organism. With every upgrade of level, the complexness will increase.
The lowest level of organization is the cell. Cell is the structural and practical unit of life. The complexness of a cell is the least as compared to the other levels of organization. A cell generally consists of flexible membranes that enclose protoplasm, a water-based cellular fluid beside a range of small functioning units referred to as organelles.
A group of cells with similar structure performing a function represent the tissue. A tissue has a lot of complexness than a cell and contains a specific function additionally.
A group of 2 or a lot of kinds of tissue with similar structure and performance makes up an organ. The complexness and functionality upgrades within the organ as compared to the tissue. Every organ performs one or a lot of specific physiological functions.A cluster of organs that work along to perform major functions or meet physiological needs of the body maybe called as the organ system.
Finally, a bunch or organs playing similar functions form up the organ system followed by several organ systems together creating up a complete operating organism. The highest level of organization is the organism level. an organism may be a living being that contains a cellular structure which will severally perform all physiological functions necessary forever.
So, organism is the level of organization that features all the other levels of organization.

The letter C in the graph represents the zone of physiological stress.
The zone of physiological stress is the range of environmental conditions in which an organism can survive, but at a reduced level of function. In the graph, this range is represented by the area between the optimal range (zone of optimal performance) and the zone of intolerance.
In the zone of physiological stress, organisms may experience a variety of negative effects, such as reduced growth, reproduction, and immunity. They may also be more susceptible to diseases and other environmental stressors.
The zone of physiological stress varies depending on the species and the environmental factor in question. For example, some species are more tolerant of heat stress than others. Similarly, some environmental factors, such as temperature, have a greater impact on physiological stress than others.

Answer:
c
Explanation:
The responsibilities of the region of the brain is regulating the body's homeostasis, hunger and eating, thirst and drinking, and other functions of basic survival.
Thus, option C is correct.
In biology, homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range).
Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium, and calcium ions, as well as the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life.
Homeostasis is brought about by a natural resistance to change when already in optimal conditions, and equilibrium is maintained by many regulatory mechanisms: it is thought to be the central motivation for all organic action. All homeostatic control mechanisms have at least three interdependent components for the variable being regulated: a receptor, a control center, and an effector.

The responsibilities of the region of the brain are highlighted below-
Regulating the body’s homeostasis, hunger and eating, thirst and drinking, and other functions of basic survival.
What is homeostasis ?
Homeostasis is a stable state of internal, external, and chemical conditions that living systems maintain. It involves numerous factors, including maintaining the body's temperature and fluid balance within certain predetermined parameters, in order for the organism to function at its best (homeostatic range). Notwithstanding changes in the environment, nutrition, or level of activity, other factors that must be controlled include the pH of extracellular fluid, the concentrations of sodium, potassium, and calcium ions, as well as the blood sugar level. One or more regulators or homeostatic processes are in charge of each of these factors, and together they all work to keep life alive.

Out of the following given choices;
A. The cell is unable to get more water into the cell.
B. The cell is unable to build more protein molecules.
C. The cell is unable to produce water molecules inside the cell.
D. The cell is unable to maintain a stable internal environment.
The answer is D. Due to high amounts of proteins in the cell, osmoticallyactive proteins cause the internal environment of the cell to be hypertonic tothe extracellular fluid. This causes excess water to enter the cell by osmosis andresulting in lysis.
