Q1. How does the climate of a place affect the agro-ecosystem? Name two other factors that affect the agro-ecosystem structure the most.

The climate of a place plays a crucial role in shaping the agro-ecosystem, which refers to the interaction between the agricultural environment and the organisms within it. Here are two ways in which climate affects the agro-ecosystem:

Temperature and Growing Seasons: Different crops have specific temperature requirements for optimal growth. The length of the growing season, which is influenced by temperature and frost-free periods, affects the types of crops that can be cultivated. Extreme temperatures, either too hot or too cold, can stress plants and limit agricultural productivity.

Precipitation and Water Availability: The amount and distribution of precipitation significantly impact agriculture. Insufficient rainfall or irregular patterns can lead to drought conditions, affecting crop yields and livestock. Conversely, excessive rainfall can result in waterlogging and increased risk of diseases. Adequate water availability is essential for plant growth, making regions with reliable water sources more suitable for agriculture.

Two additional factors that affect the agro-ecosystem structure are:

Soil Quality: The type and quality of soil in a particular area have a profound impact on agriculture. Different crops have specific soil requirements, including factors such as texture, fertility, pH, and drainage. Soil degradation, erosion, or contamination can negatively impact the agro-ecosystem by reducing productivity and sustainability.

Land Use Practices: Human activities, including agricultural practices, can significantly influence the agro-ecosystem. Factors such as deforestation, monoculture, and the use of chemical inputs (fertilizers, pesticides) can have both short-term and long-term effects on the structure and health of the agro-ecosystem. Sustainable and responsible land use practices are crucial for maintaining a healthy and resilient agricultural environment.

(a) Describe the source and sinks of greenhouse gases (GHGs).

Q4. (a) What are off-farm inputs in agriculture, and why are they called off-farm inputs?

(b) Describe the various ways in which off-farm inputs affect air quality.

Q5. Explain the future possibilities of an integrated farming system in providing food security in the region.

Q6. Discuss the components of IPM, and analyse the major issues involved in the implementation of IPM.
