An ecosystem is a complex network of living organisms (biotic components) and their non-living environment (abiotic components), all interacting and interdependent. These interactions shape the adaptations of organisms, enabling them to survive and thrive in their respective habitats.
Biotic factors include living components such as plants, animals, fungi, and microorganisms. Abiotic factors encompass non-living elements like sunlight, temperature, water, soil, and air.
Within ecosystems, food chains illustrate the transfer of energy through a series of organisms. Each level in a food chain is known as a trophic level, starting with producers (plants) and moving up to primary consumers (herbivores), secondary consumers (carnivores), and tertiary consumers (top predators).
Consider a food chain: grass → grasshopper → frog → snake → hawk.
This progressive energy loss results in an energy pyramid, where each trophic level contains less energy than the level below.
Biodiversity refers to the variety of living species within an ecosystem, including their genetic diversity. Human activities, such as deforestation, land use changes, pollution, and global warming, pose significant threats to biodiversity. Strategies like conservation efforts, sustainable practices, and responsible waste management are crucial for maintaining healthy ecosystems.
Factors like population growth, climate change, and resource availability influence food security. Sustainable farming techniques, efficient fisheries management, and biotechnology play vital roles in addressing food production challenges while minimizing environmental impact.
