The interconnectedness of life on Earth is a fundamental concept in ecology. All living organisms, from microorganisms to humans, interact with their environment and with each other in complex ways. These interactions can be broadly categorized into biotic (living) and abiotic (non-living) factors. Biotic factors include interactions between organisms, such as predation, competition, and symbiosis, while abiotic factors include physical and chemical factors like light, temperature, water, and soil.

Ecosystems are the basic units of ecology, comprising living organisms (biotic components) and their physical environment (abiotic components). Ecosystems can be terrestrial (e.g., forests, grasslands) or aquatic (e.g., rivers, oceans). In an ecosystem, energy flows through the food chain, from producers (plants, algae) to consumers (animals) and decomposers (microorganisms). Nutrients are cycled through the ecosystem, with each component playing a vital role in maintaining the balance of nature. Ecology And Environment Pd Sharma Ebook Free 16
