Two interactions within an ecosystem are predation and parasitism. In predation, predator organisms feed on prey organisms. In parasitism, parasites depend on host organisms. Which of the following correctly describes the relative numbers of organisms in parasitism or predation?

-The number of parasites is usually greater than the number of host organisms.
-The number of predators is usually greater than the number of prey organisms.
-The number of parasites is always equal to the number of host organisms.
-The number of predators is always equal to the number of prey organisms.

eukarya because is is like alche and b is bacteria and d is animals

explanation:

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
