The following observations have been made about moose living in the northeastern forests of the United States. -Male moose grow very broad antlers each year and lose them after the mating season in autumn.
-Large, heavy antlers can make escaping predators in a forest difficult if the trees grow closely together or if the underbrush is thick.
-Female moose do not develop antlers.
-Female moose raise their calves alone without the assistance of males.

What is the most likely inference that can be drawn from these observations?

A. Having antlers makes the males grow bigger so they can better compete for food in the fall.
B. Antlers make a male moose more likely to attract a mate and pass on the gene for antlers.
C. Male moose spend all their excess energy growing antlers and cannot help raise offspring.
D. Male moose without antlers are more attractive to females because they can escape predators.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
