6. all forms of energy can be converted into (click to select) .

Explanation:

To solve this fill - in - the - blank problem about the flow of energy in living things, we rely on basic concepts in Biology (a subfield of Natural Science) related to energy in biological systems.

Sentence 1

• Energy is defined as the ability to do work. Organisms need a constant supply of energy to maintain their organization and carry out metabolism. This is because all the biological processes like growth, reproduction, and maintaining cellular structures require energy input.

Sentence 2

• Kinetic energy is the energy of motion. For example, a moving animal or a molecule moving across a cell membrane has kinetic energy. Potential energy is stored energy. A molecule like glucose has potential energy stored in its chemical bonds, or a ball at the top of a hill has gravitational potential energy.

Sentence 3

• Energy flows into the biological world from the sun. The sun is the ultimate source of energy for almost all life on Earth. Photosynthetic organisms can capture solar energy and convert it into chemical energy.

Sentence 4

• Plants, algae, and some bacteria (photosynthetic organisms) use solar energy to build molecules (like glucose) that contain potential energy in the bonds between atoms. The energy is stored in the chemical structure of these molecules and can be released later.

Sentence 5

• Through chemical reactions (like cellular respiration), the potential energy within molecules can be converted into kinetic energy that organisms can use to do work. For example, the energy from glucose is used to power muscle contractions (a form of kinetic energy) or active transport across cell membranes.

Sentence 6

• All forms of energy can be converted into heat energy. This is a result of the second law of thermodynamics, which states that in any energy transformation, some energy is lost as heat.

Answer:

s for each blank:

1. do work; energy
2. motion; stored energy
3. sun
4. potential
5. kinetic
6. heat
