What is a key feature of intensive agriculture?
Large land area with low input and output.
Small land area with high input and output.
Large land area with high input and output.

Which of the following is a characteristic of extensive agriculture?
High labour and capital input per unit area.
Low labour and capital input per unit area.
High yield per hectare.

In the context of agriculture as a system, what are 'inputs'?
The final products of the agricultural process.
The resources such as seeds, water, and fertilisers used in farming.
The boundaries that define the agricultural area.
The interactions between different subsystems.
What does 'feedback' refer to in an agricultural system?
The initial resources used in the system.
The processes that occur within the system.
The information used to adjust and improve the system.
The final outputs of the system.
Which of the following is considered an 'output' in an agricultural system?
Seeds and fertilisers.
Water and sunlight.
Crops and livestock products.
Soil and land.
What role do 'boundaries' play in an agricultural system?
They determine the inputs and outputs.
They define the limits of the system.
They are the processes within the system.
They are the feedback mechanisms.
Which of the following is a subsystem in agriculture?
The entire farm.
The irrigation system.
The market where products are sold.
The climate of the region.
What is the primary focus of monitoring in an agricultural system?
To increase the size of the farm.
To ensure the system is operating efficiently.
To reduce the number of inputs.
To eliminate all outputs.
Which of the following best describes the interaction in an agricultural system?
The exchange of goods in the market.
The relationship between different subsystems like soil and water.
The final sale of agricultural products.
The initial planting of seeds.
What is a common feature of both intensive and extensive animal industries?
High use of technology.
Production of animal products.
High labour input.
Small land area.
Which of the following is a process in an agricultural system?
Harvesting crops.
Defining the boundaries.
Setting up feedback mechanisms.
Monitoring the system.
What is the primary purpose of feedback mechanisms in an agricultural system?
To increase the number of inputs.
To adjust and improve the system based on performance.
To define the boundaries of the system.
To eliminate all outputs.
Which of the following is an example of a feedback mechanism in agriculture?
Using weather forecasts to plan planting schedules.
Defining the boundaries of the farm.
Harvesting crops at the end of the season.

What is a characteristic of a subsystem within an agricultural system?
It operates independently of the main system.
It interacts with other subsystems to contribute to the overall system.
It is the final output of the system.
It is the initial input to the system.
What is a key difference between an open and a closed system?
Open systems exchange both energy and matter with their surroundings, while closed systems do not exchange matter.
Closed systems exchange both energy and matter with their surroundings, while open systems do not exchange energy.
Open systems do not exchange energy or matter with their surroundings, while closed systems exchange both.
Closed systems exchange only matter with their surroundings, while open systems exchange only energy.
Which of the following is an example of a closed system in agriculture?
A greenhouse with controlled climate and no external inputs.
A field with natural rainfall and sunlight.
A hydroponic system with external nutrient supply.
A farm using organic fertilizers and pesticides.
What is the role of technology in intensive agriculture?
To reduce the need for human labor.
To increase the land area used for farming.
To decrease the output of agricultural products.
To limit the use of fertilizers and pesticides.
