What role does metabolism play in the flow of energy?(1 point)

Metabolism causes energy to flow from one level to the next on the energy pyramid.

Metabolism converts radiant energy into chemical energy.

Metabolism breaks down glucose to create energy.

Metabolism requires energy to occur and uses a large amount of energy at each level of the pyramid.

Which trophic level is always a necessity in an energy pyramid or food chain?(1 point)

secondary consumer

tertiary consumer

producer

primary consumer

whats the answer?

Ghoste is lying, for both of the questions, its actually "Metabolism requires energy to occur and uses a large amount of energy at each level of the pyramid." for the first question on this page (third question in connexus' 4 question quick check in "Lesson 13: Flow of Energy Quick Check Science 6 B Unit 3: Matter and Energy") and the last question is "Producer"

correct me if I am wrong too, I will fix it

The answer is B

To answer the first question, "What role does metabolism play in the flow of energy?" we can break down the options provided and explain how each statement relates to metabolism and energy flow:

1. Metabolism causes energy to flow from one level to the next on the energy pyramid.
- This statement is not entirely accurate. Metabolism itself does not directly cause energy to flow from one level to the next on the energy pyramid. Metabolism refers to the chemical processes that occur within an organism to convert food into energy. However, energy flow on an energy pyramid is primarily determined by the transfer of energy through the consumption of organisms at different trophic levels.

2. Metabolism converts radiant energy into chemical energy.
- This statement accurately describes one of the fundamental functions of metabolism. Metabolism involves the conversion of various forms of energy, including radiant energy from the sun, into chemical energy that can be stored and used by organisms for their physiological processes.

3. Metabolism breaks down glucose to create energy.
- This statement is also correct. One of the key processes in metabolism is the conversion of glucose (a type of sugar) into usable energy through reactions such as cellular respiration.

4. Metabolism requires energy to occur and uses a large amount of energy at each level of the pyramid.
- This statement is partially correct. Metabolic processes indeed require energy to occur, as they involve chemical reactions. However, it is not accurate to say that metabolism uses a large amount of energy at each level of the energy pyramid. Energy is transferred and lost between trophic levels in an energy pyramid, and each level utilizes only a portion of the energy available from the previous level.

For the second question, which asks about the trophic level that is always a necessity in an energy pyramid or food chain, the correct answer is "producer." Producers, such as plants or autotrophic bacteria, are the primary source of energy in an ecosystem as they can convert sunlight into chemical energy through photosynthesis. They provide energy to all other trophic levels by being consumed by primary consumers (herbivores), which are then consumed by secondary consumers and so on, creating a flow of energy through the food chain. Without producers, there would be no energy available to sustain the other trophic levels.
