Q1. Explain the concept ‘Ecosystem Function’ with suitable examples.

Ecosystem function refers to the processes and activities within an ecosystem that contribute to its overall health, stability, and productivity. These functions are essential for maintaining the balance of nutrients, energy flow, and other crucial processes that sustain life within the ecosystem. Here are some key ecosystem functions along with examples:

Nutrient Cycling: Ecosystems recycle nutrients such as carbon, nitrogen, and phosphorus through various biological, chemical, and physical processes. For example, decomposers like bacteria and fungi break down organic matter, releasing nutrients back into the soil for plants to use. In aquatic ecosystems, phytoplankton absorb carbon dioxide during photosynthesis and release oxygen, while marine organisms recycle nutrients through the food chain.

Primary Production: This refers to the synthesis of organic matter by autotrophic organisms (mainly plants) through photosynthesis. Plants capture sunlight and convert it into chemical energy, which forms the basis of the food web. For instance, in a forest ecosystem, trees convert sunlight into biomass through photosynthesis, providing energy and nutrients for other organisms such as herbivores, which are then consumed by predators.

Water Regulation: Ecosystems play a crucial role in regulating the hydrological cycle by controlling the distribution, quantity, and quality of water. Wetlands, for example, act as natural water filters, removing pollutants and excess nutrients from water before it enters rivers or groundwater. Forests also regulate water flow by absorbing and releasing water, reducing the risk of floods and maintaining stable water levels in rivers and streams.

Climate Regulation: Ecosystems influence climate patterns by storing and releasing carbon dioxide and other greenhouse gases, regulating temperature, and influencing precipitation patterns. Forests, particularly tropical rainforests, act as carbon sinks, absorbing large amounts of carbon dioxide from the atmosphere through photosynthesis. They also release water vapor through transpiration, which contributes to cloud formation and rainfall.

Pollination and Seed Dispersal: Many ecosystems rely on the mutualistic relationships between plants and animals for pollination and seed dispersal. Pollinators such as bees, butterflies, and birds facilitate the reproduction of flowering plants by transferring pollen between flowers. Seed dispersers such as birds, mammals, and insects help plants colonize new areas by dispersing seeds through their feces or by carrying them to different locations.

Erosion Control and Soil Formation: Ecosystems, particularly forests, grasslands, and wetlands, help prevent soil erosion by stabilizing soil with roots, reducing the impact of wind and water erosion. They also contribute to soil formation through the accumulation of organic matter and the breakdown of rocks and minerals by microorganisms and plant roots.

These are just a few examples of the diverse functions that ecosystems perform. Each ecosystem has its unique set of functions depending on its structure, composition, and environmental conditions. Maintaining the integrity of these functions is crucial for the sustainability of ecosystems and the well-being of human societies.

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.
