Answer:
Some bacteria are decomposers and break down the complex nitrogen compounds in dead organisms and animal wastes. This returns simple nitrogen compounds to the soil where they can be used by plants to produce more nitrates. Plants take up nitrogen compounds through their roots. Animals obtain these compounds when they eat the plants. When plants and animals die or when animals excrete wastes, the nitrogen compounds in the organic matter re-enter the soil where they are broken down by microorganisms

Answer: second
Explanation:Early humans most likely experienced changes in climate forcing migration to find animals for food, changes in climate alternating rivers with droughts and floods and changes in environment causing animal habits changes.
Explanation:
All the changes that early humans could have experienced, I think, are related to the changes that animals and the lands could have suffered. They lived much more closer to them than we do now; now we sometimes don't realize how global warming is affecting our planet because we are not that close to the lands and the crops and we don't usually raise animals for our consumption, we just buy at the shop. But, early humans could sense every change related with that because this was the way they lived. So, migration to find animals, changes in climate alternating rivers with droughts and floods and changes in animal habits are the ones I believe they could have suffered.
