Why are migratory species harder to protect

Migration.

Explanation:

Migratory species are species that migrate to other countries, hemispheres and even continents, at certain times of the year. The two main cause of migration are food and climate.

When a species migrates too much, it is difficult to protect them, since they will keep changing locations, and there will be a different problem in each one of them.

answer: c

explanation:

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.
