Final answer:
Turf management is an example of horticulture, which is the cultivation of plants for food and other purposes. 'Crop pest control' also falls under horticulture. In contrast, animal husbandry and forestry do not pertain to horticulture as they focus on animals and forest management, respectively. The answer is option A.
Step-by-step explanation:
The question asks which of the following is an example of horticulture: a. turf management, b. animal husbandry, c. forestry, and d. all of the above. The correct answer is turf management.
Horticulture is a branch of plant agriculture that specifically deals with the art, science, technology, and business of growing plants, which include vegetables, fruits, nuts, seeds, herbs, sprouts, mushrooms, flowers, seaweeds, and non-food crops such as grass and ornamental trees, and plants. Therefore, turf management, which involves the maintenance and care of grasses for sports, residential, or commercial use, falls under this category. Other options like animal husbandry and forestry do not qualify as horticulture because they are not focused on plant cultivation.
Option d, 'crop pest control' is also a component of horticulture, as it involves managing pests that can affect plant health and yield. Options like 'converting a prairie to a farm field', which causes habitat loss, and 'soil tilling', which is more indicative of conventional agriculture, also relate to agricultural practices but are broader concepts and might not necessarily be limited to horticulture.
