Question

all organisms need energy from food to live and grow. inside an organisms cells, food molecules like carbohydrates, lipids, and proteins can be broken down and rearranged through chemical reactions to release energy. animals get the food they need by consuming plants or other animals. but how do plants get the food they need to survive? most plants use energy from the sun to make food molecules in their cells through a series of chemical reactions collectively called photosynthesis. animals are consumers. they get food by consuming plants or other animals. plants are producers. they make food through photosynthesis. select the true statements. photosynthesis transforms light energy into chemical energy. animals need food molecules, but plants dont. photosynthesis is a single chemical reaction. chemical energy can be used for cell growth.

Explanation:

• Photosynthesis transforms light energy into chemical energy: This is correct. During photosynthesis, plants use sunlight (light energy) to convert carbon dioxide and water into glucose (a form of chemical energy) and oxygen.
• Animals need food molecules, but plants don’t: This is incorrect. Plants need food molecules too. They make their own food (glucose) through photosynthesis, which is then used for various cellular processes like growth, repair, and reproduction.
• Photosynthesis is a single chemical reaction: This is incorrect. Photosynthesis is a series of complex chemical reactions. It has two main stages: the light - dependent reactions (which require light) and the light - independent reactions (Calvin cycle).
• Chemical energy can be used for cell growth: This is correct. Both plants and animals break down food molecules (which contain chemical energy) through processes like cellular respiration. The energy released is used for cell growth, repair, and other life - sustaining activities.

Answer:

• Photosynthesis transforms light energy into chemical energy.
• Chemical energy can be used for cell growth.
