Biotic Components

• Producers: Mainly plants, they convert solar energy into chemical energy through photosynthesis, forming the base of the food web.
• Consumers: Animals that rely on other organisms for food, divided into herbivores, carnivores, omnivores, and decomposers.
• Decomposers: Fungi and bacteria that break down dead organic matter, recycling nutrients back into the ecosystem.

Abiotic Components

• Soil: The medium for plant growth, composed of minerals, organic matter, water, and air, influencing vegetation type and productivity.
• Water: Essential for life, influencing soil moisture, plant growth, and animal habitats.
• Climate: Determines the overall environment of the ecosystem, including temperature, precipitation, and sunlight, shaping the types of life that can thrive.
• Air: Provides essential gases like oxygen for respiration and carbon dioxide for photosynthesis.
• Light: Solar energy is crucial for photosynthesis, driving the primary production in ecosystems.

The interaction between biotic and abiotic components defines the unique characteristics and functions of each terrestrial ecosystem, supporting a diversity of life forms and ecological processes. Understanding these interactions is key to managing and conserving terrestrial ecosystems effectively.

Energy flow and nutrient cycling are fundamental processes that drive the functioning of terrestrial ecosystems. These interconnected cycles support life, maintain ecological balance, and ensure the sustainability of ecosystems.

Energy Flow

Energy in terrestrial ecosystems flows through a food chain or web, starting from the sun and moving through producers to consumers and then to decomposers. This flow of energy is crucial for the survival of ecosystem inhabitants and dictates the structure of the ecosystem.

• Solar Energy: Captured by producers (plants) through photosynthesis.
• Consumers: Use the energy stored in plants or other animals they eat.
• Decomposers: Release energy from waste and dead organisms, making it available again for producers.

Nutrient Cycling

Nutrient cycling involves the recycling of nutrients necessary for life, such as carbon, nitrogen, and phosphorus, through different components of the ecosystem.

• Carbon Cycle: Moves carbon between the atmosphere, living organisms, and the earth, crucial for regulating the earth"s climate.
