Answer 1

Answer:

The correct answer is option A) "All living organisms use energy".

Explanation:

Even though living being use different strategies to obtain energy, an unifying principle among them is that all living organisms use energy to live. Plant use photosynthesis, which allows them to use sunlight, carbon dioxide and water to obtain energy. This classifies plant as producers, whereas animals that consume plants are primary consumers, animals that consume the animals that consume plants are second consumers, and so on.
