because both terrestrial and aquatic environments are belong to the ecosystem

Absolutely, both terrestrial and aquatic environments are integral components of Earth's ecosystem, contributing to its diverse and interconnected web of life. Here's how they both fit into the broader ecosystem concept: 1. **Interconnectedness**: Terrestrial and aquatic ecosystems are not isolated; they interact in many ways. Rivers and streams flow through land and empty into seas, carrying nutrients and organisms that support both environments. 2. **Biodiversity**: Each environment contributes significantly to global biodiversity. From the vast variety of mammals and plants found on land to the multitude of fish, algae, and microscopic organisms thriving in water bodies, both systems highlight the richness of our planet's flora and fauna. 3. **Energy Flow**: Both terrestrial and aquatic ecosystems play a role in the flow of energy through food chains and webs. Energy captured by primary producers (e.g., plants on land or phytoplankton in water) is transferred to upper trophic levels, supporting diverse life forms in different ecological niches. 4. ** Material Cycles**: These ecosystems are part of global nutrient cycles. Terrestrial processes help convert organic matter back into usable elements through decomposition, while aquatic environments act as a sink for many materials, including carbon, and contribute to nutrient recycling. 5. ** Environmental Services**: Both offer invaluable ecosystem services such as water purification in aquatic ecosystems and climate regulation via forests (terrestrial). Aquatic ecosystems also provide food security through fishing, while terrestrial ecosystems provide resources like wood and material for agriculture. 6. ** Adaptations and Specializations**: Each promotes species adaptation based on its specific conditions. Terrestrial creatures have evolved to manage dry conditions and gravity, whereas aquatic species have developed to thrive in a buoyant environment with unique pressures and temperature gradients. 7. **Resilience and Stability**: Both ecosystems are important for regional and global stability, offering habitat for countless organisms, providing recreational opportunities, and acting as indicators of environmental health. 8. **Evolutionary Considerations**: Studying aquatic and terrestrial ecosystems helps us understand Earth’s evolutionary history and present-day ecological dynamics, which in turn informs conservation efforts. Recognizing both terrestrial and aquatic ecosystems as parts of one larger ecosystem framework underscores the importance of valuing environmental health and balance across all corners of our planet. Efforts to protect one often benefit the other, illustrating the inseparable roles these environments play in the grand tapestry of Earth's ecology.
