The human body has about 10 bacterial cells for every eukaryotic cell. Bacteria coat our skin, gut, and mouth. Also present are

protists, Archaeans, and viruses. Collectively, these organisms are our microbiota. For most members of our microbiota, our body provides their environment (or space to live). They, in turn, have no effect on us. This is an example of: predation. mutualism. commensalism. an antagonistic relationship.

Answer:

commensalism

Explanation:

Commensalism is a type of ecological interaction between two species in which one speices benefits while other is unaffected. Commensalism  also can be considered as a type of symbiosis-two species that live together. The interaction between human and its microbiota is beneficial for microbiota while it has no effects on humans.

Although, some bacteria (gut bacteria) can help in digestion. In this case, interaction with human is mutualism (both have benefits).

Agricultural lands frequently require nutrient augmentation because
fenix001 [56]

The given is incomplete as the options are missing. The correct options for the given question are as follows-

(A) cultivation of agricultural land inhibits the decomposition of organic matter

(B) nitrogen-fixing bacteria are not as plentiful in agricultural soils because of the use of pesticides

(C) land that is available for agriculture tends to be nutrient-poor

(D) the nutrients that become the biomass of plants are not cycled back to the soil on lands where they are harvested

Answer:

Option (D)

Explanation:

In order to carry out agricultural practices, the soil must be rich in essential nutrients for the growth of crops. The soil fertility is a key role in the production of crops.

This agricultural land often requires a large amount of these nutrients and minerals because some of the nutrient minerals are converted into plant biomass which is then used up to produce energy in other sectors. So, the nutrients that were present in the soil are taken away and not transferred back into the soil. This means that the nutrient cycle gets affected. Due to this reason, there requires a constant supply of nutrients into the agricultural fields.

Thus, the correct answer is option (D).
