Solution:
The correct answer is:
1: All living things, both animals and plants, breathe. Breathing is intended to release energy to be used by organisms. It is a reaction that oxidizes a compound rich in energy, obtaining poor products in it (carbon dioxide and water).
2: Plants contain a wide variety of pigments that give rise to the colors that we see in them. These pigments are chlorophyll-a (intense green), chlorophyll-b (green), carotenes (orange), xanthophylls (yellow), anthocyanins (reddish, purple, or bluish), and phycobilins (red).
3. Autotrophic organisms are those that have the ability to produce their own food from inorganic substances, which is why they can also be known as producers or vegetables. The main examples of autotrophic organisms are plants, algae, archaea, and various bacteria.
