Autotrophs are organisms that can occupy the first trophic level of a food chain but not perform photosynthesis.

What type of organisms occupies the primary trophic stage?

Producers make up the primary trophic stage. Manufacturers, also called autotrophs, make their very own food and no longer rely on every other organism for vitamins. most autotrophs use a process referred to as photosynthesis to create food (a nutrient called glucose) from daylight, carbon dioxide, and water.

Autotrophs no longer consume different organisms, they are the primary trophic degree. Autotrophs are eaten by means of herbivores, organisms that devour plants. Herbivores are the second trophic degree.

She dissolves 3.0 grams of salt in the first sample, and uses the second sample of pure water for a control group. She then heats each sample until it boils and records the temperature while it is boiling.

Answers

Answer:

The dependent variable is: the temperature at which liquid boils.

Explanation:

The Dependent variable in a study or research is the variable that is measured after the modification or change in the particular research independent variable.

In this case, the independent variable is the treatment that liquid or water get which is the addition of 3 gm salt, and in the response to this treatment change in the boiling point of the liquid will be the dependent variable.

Thus, the correct answer is -  the temperature at which liquid boils.
