Q1. Explain the concept ‘Ecosystem Function’ with suitable examples.
Ecosystem function refers to the processes and interactions within an ecosystem
that result in the flow of energy, cycling of nutrients, and maintenance of
ecological balance. These functions are essential for the survival and
sustainability of the ecosystem. There are several key ecosystem functions:
Nutrient
Cycling: Ecosystems rely on the recycling of nutrients such as carbon,
nitrogen, and phosphorus. For example, decomposers break down organic matter
into nutrients that can be absorbed by plants. Plants, in turn, take up these
nutrients, which are then passed along the food chain when herbivores consume the
plants and carnivores consume the herbivores. Decomposition of organic matter
by microbes and fungi further releases nutrients back into the soil, completing
the cycle.
Primary
Production: This refers to the process by which autotrophic organisms, primarily
plants, convert sunlight into chemical energy through photosynthesis. This
energy is then used by organisms within the ecosystem for growth and
reproduction. For example, in a forest ecosystem, trees capture sunlight to
produce sugars, which are consumed by herbivores, and then by carnivores, thus
forming the basis of the food web.
Water Cycling:
Ecosystems play a crucial role in the cycling of water. Plants absorb water
from the soil through their roots and release it into the atmosphere through a
process called transpiration. This water vapor eventually condenses and falls
back to the Earth's surface as precipitation, replenishing freshwater sources.
Wetlands and forests are particularly important in regulating water flow,
reducing flooding, and maintaining water quality.
Pollination and
Seed Dispersal: Many ecosystems rely on pollinators such as bees, butterflies,
and birds for the reproduction of flowering plants. These pollinators transfer
pollen from one flower to another, facilitating fertilization and the
production of seeds and fruits. Similarly, seed dispersal by animals ensures
the distribution of plant seeds across different habitats, promoting genetic
diversity and colonization of new areas.
Climate
Regulation: Ecosystems play a crucial role in regulating climate patterns by
absorbing and releasing greenhouse gases such as carbon dioxide and methane.
Forests, for example, act as carbon sinks, absorbing CO2 from the atmosphere
during photosynthesis and storing it in biomass and soil. Wetlands also play a
significant role in carbon sequestration. By regulating greenhouse gas
concentrations, ecosystems help mitigate the impacts of climate change.
Soil Formation
and Erosion Control: Ecosystems contribute to soil formation through the
weathering of rocks and the accumulation of organic matter. Vegetation helps
stabilize soil, reducing erosion caused by wind and water. Additionally, soil
organisms such as earthworms and bacteria play a crucial role in nutrient
cycling and soil structure maintenance.
These examples
illustrate how various ecosystem functions are interconnected and essential for
maintaining the health and balance of natural systems. Disruption of these
functions can lead to ecological imbalances, loss of biodiversity, and negative
impacts on human well-being. Therefore, understanding and conserving ecosystem
functions are critical for sustainable management of natural resources and the
environment.
Q2. What are the
available soil types in your country? Explain.
Q3. Write an essay on
the mineral resources, use and management in your country.
Q4. Discuss the major
opportunities and challenges of promoting genetic diversity in your country
with suitable examples.
