Question

question 4 1 pts symbiosis is a combination of different organisms working together and get different results. this term ______ refers to when one species benefits while the other species is unaffected? commensialism parasitism mutualism competition question 5 1 pts the conversion of nitrogen gas to ammonia is called __________? renitrofixation nitrogen fixation fixed nitrogen denitrification

Explanation:

• For Question 4: Commensalism is a type of symbiotic relationship where one species benefits and the other is neither helped nor harmed. Parasitism is when one organism (parasite) benefits at the expense of the other (host). Mutualism is when both species benefit from the relationship. Competition is when organisms compete for resources.
• For Question 5: Nitrogen fixation is the process by which nitrogen gas ($N_2$) in the atmosphere is converted into ammonia ($NH_3$). Renitrofxiation is not a standard term. Fixed nitrogen refers to nitrogen that has been converted into a more reactive form, but the process of conversion is nitrogen - fixation. Denitrification is the process by which nitrate is reduced to nitrogen gas.

Answer:

Question 4: A. Commensialism
Question 5: B. Nitrogen Fixation
