Answer:
I and III only
Explanation:
Crop rotation is a farm practice that involves cultivating different species of crops on the same land at different seasons. In other words, the different crops are rotated. Crop rotation is done for various reasons including; improvement of soil fertility, pest and disease control etc.
In this case, a crop rotation of various grains and legumes would be an appropriate solution for the following problems:
- The nutrients in the soil on a farm are being depleted: Legumes are known to be rich in nitrogen and hence add nitrogen to the soil due to the nitrogen-fixing microbes in their roots. Hence, rotating between grains and legumes can help return the depleted nutrients (by grains) to the soil.
- A particular kind of pest is infesting the soil on a farm: Most pests are usually crop-specific, hence, planting only one type of crop can make that soil be infested with a particular kind of pest. However, rotating between crops such as grains and legumes can make a particular pests become scarce or less populated.
Answer:
Land able to be used for farming is called "cultivable land". Farmland, meanwhile, is used variously in reference to all agricultural land, to all cultivable land, or just to the newly restricted sense of "arable land".

The answer is a production of spores which are used for
reproduction.
<span>In fungi, the fruiting body contains spores, which are the
fungi's reproduction units. Spores are released by wind, rain, or animals. Once
they land on an adequate surface they grow into hyphae, and eventually form a
mycelium. The mycelium can later develop into the fruiting body and, thus, the
cycle is repeated.</span>
Answer:
Symbiosis and metabolic cooperation.
Explanation:
Symbiosis is a term called for bacteria that live in symbiosis with another organism or with each other, as we can see here there is a tow bacteria living in the same place (gut), one attached to the surface of the gut and another one synthesize ATP which can be used by other bacteria which made both of them benefits from a metabolic reaction that made by one bacteria.
