The study of the relative power and limits of genetic and environmental influences on behavior is known as

Behavior genetics.

Explanation:

Genetics may be defined as a branch of biology that studies the inheritance and variation of the inherited characters. Mendel is known as the father of the genetics.

Behavior genetics may be defined as the field of the scientific research that uses the genetic methods to investigate the behavioral differences in the individual. This genetics uses the limits of genetics and environmental impact on the individual's behavior.

Thus, the answer is behavior genetics.

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.

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects
