What is a single celled organism that have no nucleus and can either benefit or harm the body
lidiya [134]

Answer:

Bacteria

Explanation:

Bacteria have no true nucleus because it's a prokaryote. It couldn't have been a virus because all naturally occurring viruses are pathogenic unless treated by radiation.

We have two types of bacteria,

  1. Pathogenic
  2. Commensals

Pathogenic bacteria will definitely cause disease. Commensals, however, have don't harm us and have the ability to help us.

Eg: Flora (bacteria) in our intestines produce vitamin K and most of the vitamin B complex. They also compete with the pathogenic bacteria that you might've ingested and don't allow them to increase to the number that can cause disease.

Can someone help me out please?!!!!!!!!
liraira [26]
Producers are organisms that make their own food. Plants would be an example. Primary consumers would be those that eat producers(plants,algae). Secondary consumers are animals that eat primary consumers. Herbivores are animals that only eat plants. Carnivores are those that only eat meat and don’t eat plants. Omnivores are those that eat both meat and plants. De composers are those that decompose organic material like dead animals. The herbivores here are the kangaroo rats,grasshoppers and bunny’s. The carnivores here are the hawk,lizard,tarantula and rattlesnake. I don’t think there is an omnivore. And the only decomposed here is the bacteria. As it decomposes the bodies of the animals when they are dead.
