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.
Q2. a) Explain the
impact of rising atmospheric CO2 on agricultural production.
(a) Describe the
source and sinks of greenhouse gases (GHGs).
Q3. How can we
maintain the long-term fertility of soils? List the steps to maintain soil organic
matter at an optimum level.
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.
Q7. Discuss the major
socio-economic factors that influence the agricultural sector in a country.
Q8. (a) Discuss the
scope and limitations of biotechnology in sustaining agricultural production.
(b) How do
post-harvest technologies differ in the storage of food grains and fruits and
vegetables?
Q9. (a) Why and when
should we incorporate crop residues in the soil?
(b) Enumerate various
changes that take place during composting.
Q10. (a) Define agro
forestry. Describe various systems of agroforestry.
(b) What are the major
areas for the development of sound social forestry system?
