Yes, several organisms like certain deep-sea creatures and fungi can survive without energy from the sun. They derive their energy from chemical reactions or by absorbing nutrients from surroundings.
Yes, there are several organisms that can survive without relying on the energy from the sun. These organisms are often found in extreme environments where sunlight is minimal or absent such as deep ocean trenches. These organisms derive their energy from sources other than sunlight - most commonly via chemosynthesis. For instance, deep-sea hydrothermal vent ecosystems harbor a variety of organisms that survive without sunlight. Instead, they rely on chemicals present in the vent fluids as their energy source.
Another example is fungi, which absorbs nutrients from other organisms and doesn't depend on the sun for energy. Also, there are certain types of bacteria like the ones found in our gut that can survive without energy from the sun.

b. Experimental group
c. Hypothesis
d. Variable
The factor of interest in an experiment is called the Variable.
In an experiment, the factor of interest is called the Variable. The variable is the specific aspect or condition that is being tested or manipulated in an experiment to determine its effect on the outcome.
For example, if you are experimenting to test how different amounts of fertilizer affect plant growth, the variable would be the amount of fertilizer applied. In this case, the amount of fertilizer is the factor of interest that is being studied.
Therefore, the correct answer is d. Variable.
