The management of farm resources in a profitable and sustainable way under the given conditions by a farm household is known as a. farming system b. economic system c. commercial system d. subsistence farming ans=

Explanation:

Except when it serves a descriptive purpose, farm management is the science (and art) of optimizing the use of resources in the farm component of farm-households, i.e., in systems of Order Level 10 (see Figure 1.2), and of achieving the optimal functioning of these systems in relation to household-specified objectives; and since Order Level 10 systems consist structurally of subsystems, farm management is also concerned with the operation of subservient subsystems of Order Levels 1 to 9 in such fashion as to optimize the whole-farm system. However, for reasons discussed in Chapter 1, it is often essential, especially when dealing with small farms, that farm management extends also to the family or household component, thus its true scope extends to Order Level 12 systems. A second consideration is that the village is sometimes a more relevant unit for analysis than the farm, and where this is so the scope of 'farm' management extends to systems of Order Levels 1 to 13

the wrong statement is - c. a desert had more biodiversity than a marsh.

the deserts are one of the places of the planet where there's the least biodiversity. the reasons for that are the climate and the lack of food sources, which hampers both the number of the species that can survive in it, and the number of the individuals in the species itself.

the marshes, on the other hand, are places where there's perfect conditions for lots of organisms to thrive. the temperature is moderate and nice, the amount of water and the food sources are on a high level, so there's an abundance of both plant and animal life in them.
