Use the evidence in the text to select the photosynthetic organism.
Echidnas are egg-laying mammals. An echidna is covered in spines and has a long snout that it uses to eat ants and termites. Yucca plants have long, sharp leaves. These leaves have a waxy covering. Yucca plants use carbon dioxide and water to make their food.
Organisms that carry out photosynthesis are called photosynthetic organisms. During photosynthesis, these organisms use light energy, carbon dioxide, and water to produce sugars and oxygen.
Photosynthetic organisms also often have the following characteristics:
They are producers, which are organisms that make their own food inside their cells. Because producers make their own food, they typically do not eat other organisms.
Their cells contain chloroplasts, which are cell structures where photosynthesis occurs.
Their chloroplasts often contain a green substance called chlorophyll. Chlorophyll captures light energy from the Sun to power photosynthesis.
They use the sugars they produce during photosynthesis as food. This food provides energy that helps the organisms live, grow, and reproduce.
This organism is photosynthetic:
The text tells you that yucca plants use carbon dioxide and water to make food. This is evidence that the yucca plant is a photosynthetic organism.
This organism is not photosynthetic:
The text does not provide evidence that the echidna is photosynthetic.
