It's estimated that without the development of this agricultural technology, the global population would
never have exceeded 4 billion people.

Industrial fixation of Nitrogen

Explanation:

Industrial fixation of nitrogen has enabled humans to be able to make nitrogen fertilizers that are able to supply plants with much needed nitrogen that they need to survive. Indeed it is said that up to 40% of the nitrogen taken up by plants is from artificial sources.

The world's population might not be what it is today without this invention because it was able to return nitrogen to the soil at a time when humans needed it because we had been intensively farming land which led to it losing nutrients.

More nitrogen allowed us to keep farming and keep feeding the population which then exploded.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
