D) Least genetic diversity is the correct option
A cropland ecosystem will have a major crop cultivated in a given area. It shows that the diversity in that particular area will be least. Whereas it is the opposite when the forest ecosystem is considered.
The cropland Ecosystem:
This is a manmade ecosystem. Man has been doing his best in modifying the croplands to get the maximum benefit out of them. A cropland ecosystem may be illustrated by crops like wheat, maize, rice, sugarcane, etc. It has the following components.
1. Producers: A crop along with the weeds growing in the field is the producers of a cropland ecosystem. In the cropland ecosystem of maize, weeds like Cynodon dactylon, Euphorbia hirta, Alysicarpus, Launea nudicairlis are very common.
2. Consumers: Herbivores are the primary consumers of the cropland ecosystem. These include rats, rabbits, birds, men, and insects. The second-order and the third-order consumers are represented by frogs, snakes, birds such as hawk, etc.
3. Decomposers and transformers: Bacteria and fungi like Bacillus, Aspergillus, Clostridium, Agaricus, Mucor, Aspergillus, and Fusarium are common decomposers and transformers of cropland ecosystem of maize.

Characteristic Feature of Cropland Ecosystem
Cropland ecosystem refers to the land area that is used for agriculture, and it is characterized by specific features that differentiate it from other ecosystems. The characteristic feature of cropland ecosystem is:
Least Genetic Diversity
Cropland ecosystems have low genetic diversity due to the practice of monoculture farming, which involves planting a single crop on a large scale. This practice is common in modern agriculture because it facilitates management and harvesting of crops. However, it has led to the loss of genetic diversity, making crops more vulnerable to diseases and pests. Additionally, the use of high-yielding varieties and hybrid seeds has further reduced genetic diversity.
Other features of cropland ecosystem include:
Presence of Weeds
Weeds are a common problem in cropland ecosystems because they compete with crops for nutrients, water, and sunlight. They can also serve as hosts for pests and diseases, and reduce crop yields. Farmers use various methods to control weeds, including tillage, herbicides, and manual weeding.
Ecological Succession
Ecological succession refers to the process by which a community of organisms gradually changes over time. In cropland ecosystems, the process of succession is disrupted by the regular removal of crops. As a result, the ecosystem remains relatively stable, with the same dominant species occupying the same niche for many years.
Presence of Soil Organisms
Soil organisms play an essential role in cropland ecosystems by decomposing organic matter, cycling nutrients, and improving soil structure. However, intensive agricultural practices such as tillage, use of pesticides, and fertilizers can harm soil organisms and reduce their diversity.
In conclusion, cropland ecosystems have unique features that make them different from other ecosystems. The characteristic feature of cropland ecosystem is the least genetic diversity resulting from monoculture farming.
