Answer:  A)the populations of all other organisms in the food web would decrease because there would be less energy available in the ecosystem.

A food chain is a linear sequence of transfer of food and energy when one organism is consumed by other organisms. A food web is an interconnection of different food chains. One organism is dependent upon other organism for it's food requirement. In the given situation, the decline in the phytoplankton population will initially cause decline in the population of krill and zooplanktons but finally may also affect the population of other organisms which feed upon krill and zooplanktons. Therefore, the energy distribution in the food web will also be affected.

The answer is A, because the phytoplankton is the foundation of this food web. Without your foundation, "the building will begin to crumble".

Because plants go through a cycle(the cycle is seed, seedling, plant, flower and tree.) and it takes time for the plant food, water, and nutrients to go though the plant.

31. The data in the accompanying graph show evidence of disease in the human body. D 38 - - E Body Temperature (°C) 377 А IDOT B

Homeostasis keeps the organism in a dynamic equilibrium within the homeostatic range. <em>A </em><em>disruption i</em><em>n </em><em>dynamic equilibrium </em><em>is indicated by the </em><em>temperature </em><em>change between point C and D.</em> Option C is correct.

<h3>What is homeostasis?</h3>

Homeostasis is the organism's capacity to keep the body in constant internal equilibrium, even when the external environment is oscillating.

Homeostasis is critical to keep the correct internal functioning of the body.

Different functions -blood pressure, body temperature, respiratory rate, and blood glucose levels, among others- are kept in a<u><em> </em></u><u><em>restricted range</em></u><u><em> </em></u>around a reference point, even though external conditions may be changing.

When a sudden change occurs in the internal functioning that disturbs this equilibrium, the organism counters it back by negative or positive feedback.

<h3>Graph interpretation</h3>

In the exposed graph we can see,

  • The restricted range of homeostasis at a constant temperature around 37ºC.

  • Six reference points (A-F) withing 12 hours.

  • Dynamic equilibrium is kept in the range of homeostasis around 37ºC, excepting for point D that reaches 38ºC.  

The references point A, B, and C suggest that during the first 10 hours, approximately, the body was in equilibrium.

A change in the internal functioning broke the equilibrium, rising temperature to 38ºC, out of the homeostatic range.

The organism took the internal values to their original state, and at points E and F, the organism was in equilibrium again.
