Farming is often done on the large-scale to allow for high-volume production. For example, tomatoes can be grown in large open fields and harvested by machinery instead of by hand.  The harvester machine not only collects (nearly) all the tomatoes, it also removes the green unripe fruits!  Harvesters like this one greatly reduce the time needed to obtain crops but challenges remain.   What is one biotic factor that could limit the tomato yield?  List and briefly explain how this factor causes a yield decrease What is one strategy you could use to try and reduce losses from this biotic factor?

Soil Ecosystem

Soil provides a habitat or living environment for a large number of different species of organisms as well as plants. It provides all the essential nutrients and minerals for plants to grow. All these together form the soil ecosystem.
