. Energy flows from the Sun or from rocks through the primary producers and the successive levels of consumers.
Explanation:
Energy flows only through the sun not the rock because sun is the ultimate source of energy which can be used by the plants for making their own food in the form of glucose during the process of photosynthesis. This plant is then eaten by primary consumer known as herbivore. These primary consumer is eaten by secondary consumer is called carnivores.

The domain of the new species of unicellular microorganism in an undersea thermal vent that lacks a nucleus is Archeae.
<h3>What is domain?</h3>
Domain in biology refers to the highest rank in the classification of organisms, above kingdom.
The three domain of organisms are as follows:
- Prokarya or Bacteria
- Archaea
- Eukarya
Members of Prokarya and Archaea do not possess a membrane-bound nucleus, however, the major difference between them is that members of domain Archaea are found in extreme habitats e.g. hot regions.
Therefore, the domain of the new species of unicellular microorganism in an undersea thermal vent that lacks a nucleus is Archeae.

Your brain does this because it knows that you are hungry, and consequently the brain signals the digestive muscles to contract. There is also, usually, some gas in the intestines and stomach. The noises come out when the mixture of the gas and fluid, digestive juices, squirt through a opening that separates the stomach and small intestine.
Sometimes the noises happen because of an excessive amount of gas in the small intestine.
