B. Solar energy


C. Chemical energy


D. Potential energy

An -- C

Don't we need sunlight?

B thanks..

Four students are discussing the kind of energy that's fundamental to life on Earth. Thomas says it's electrical energy. Susan opts for solar energy. Lawrence argues in favor of chemical energy. Kimberly is sure it's mechanical energy. Who is correct?

To determine which kind of energy is a fundamental requisite for life on Earth, let's take a closer look at the options provided.

A. Electrical energy: Electrical energy is the energy associated with the movement of charged particles, typically through a conductor. While electrical energy is essential for many technological applications, it is not a fundamental requisite for life on Earth.

B. Solar energy: Solar energy, also known as radiant energy, is derived from the Sun. It plays a crucial role in sustaining life on Earth. Solar energy provides heat and light, which drive various biological processes such as photosynthesis, the primary source of energy for most living organisms.

C. Chemical energy: Chemical energy is stored in the bonds between atoms and molecules, and it is released during chemical reactions. This type of energy is essential for life on Earth as it is involved in various metabolic processes that organisms rely on to obtain energy from food.

D. Potential energy: Potential energy is the energy possessed by an object due to its position or state. While potential energy exists in different forms, such as gravitational potential energy, elastic potential energy, etc., it is not a fundamental requisite for life on Earth.

Considering the above explanations, the correct answer is C. Chemical energy. Chemical energy is necessary for life on Earth as it is involved in the production of ATP, the main energy currency in living organisms. It is obtained through the consumption of food and is used for various cellular functions, including growth, repair, and movement.
