(a) (i) Differentiate between intensive system and extensive system of livestock management. (ii) State five disadvantages of keeping livestock on free range system.
(b) State six ways in which ornamental plants are important.
(a)
(i) Intensive system and extensive system of livestock management differ in the level of input and management involved. Intensive system involves high input and management with a small number of livestock kept in a small area while extensive system involves low input and management with a large number of livestock kept in a large area.
(ii) Five disadvantages of keeping livestock on free range system are:
Increased risk of disease transmission among animals due to closer contact and exposure to pathogens.
Limited control over breeding and genetics of animals.
Lack of proper shelter and protection from predators, adverse weather conditions, and theft.
Overgrazing and degradation of pastureland, which can lead to soil erosion and reduced productivity.
Difficulty in monitoring and managing animal health and welfare.
(b) Six ways in which ornamental plants are important are:
Aesthetic value: Ornamental plants are grown for their beauty and add color, texture, and interest to gardens, parks, and public spaces.
Environmental benefits: Ornamental plants can help reduce air pollution, noise pollution, and soil erosion, and contribute to carbon sequestration.
Economic benefits: The production and trade of ornamental plants contribute to local and national economies through employment and revenue generation.
Cultural significance: Ornamental plants have cultural and historical significance in many societies, and are often used in art, literature, and religious practices.
Psychological benefits: Exposure to ornamental plants has been linked to improved mental health, reduced stress, and increased feelings of happiness and well-being.
Educational value: Ornamental plants provide opportunities for learning about botany, horticulture, and ecology, and can be used for educational purposes in schools and other institutions.
Explanation: Ornamental plants serve many purposes, from beautifying our surroundings to providing environmental, economic, cultural, and psychological benefits. They also have educational value, making them a valuable resource for learning and research.
