euglena
euglena are unicellular, freshwater organisms that are very common in ponds and small bodies of water, especially if they are rich in nutrients and consequently high in algae. euglena feature both plant and animal characteristics. euglena are able to perform photosynthesis like plants. they can also get energy from consuming green algae.
during photosynthesis energy is obtained from the sun and converted to ______ during cellular respiration, the bonds are broken and energy is released.
○ kinetic energy
○ thermal energy
○ mechanical energy
○ chemical energy

Explanation:

The question is about the energy conversion in Euglena during photosynthesis and cellular respiration. Photosynthesis converts solar energy to chemical energy (stored in glucose), and cellular respiration breaks glucose bonds to release energy. The energy obtained from the sun in photosynthesis is converted to chemical energy (stored in organic molecules like glucose) which is then used in cellular respiration. So the correct option is the one related to chemical energy.

Answer:

chemical energy (the option labeled "chemical energy")
