An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms.Group of answer choices

These organisms are called autotrophs. Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Examples of autotrophs include plants, algae, and some types of bacteria. Here are the steps:

1. Autotrophs take inorganic substances from their environment, such as carbon dioxide and water.

2. They use energy from the sun (in the case of photosynthetic organisms) or from chemical reactions (in the case of chemosynthetic organisms) to convert these substances into organic food molecules, such as glucose.

3. This process is called photosynthesis or chemosynthesis
