Explanation:

Infectious diseases were more easily spread because of poor sanitation. People may not have cleaned surfaces daily, washed their hands, or taken a bath. Poor hygiene and sanitation could've been one reason why infectious diseases were more easily spread. Another reason would be that there are more medications nowadays. Antibiotics and vaccinations weren't as devloped and successful as they are now. Infectious diseases were easily spread because of poor sanitation and weak medications.

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.
