An ecosystem is an active complex of living organisms in interaction with each other and with their physical environment. Components include plants, animals, microorganisms, water, soil, and air interrelating to form a functioning unit. Ecosystem interactions are involved in energy flow and nutrient cycling-the two basic processes sustaining life. Primary producers within the food web, including plants and algae, capture solar energy through photosynthesis. This energy and nutrients are transferred and recycled through consumers and decomposers, such as herbivores, carnivores, and microorganisms, inside the ecosystem.

Biodiversity is the number of life forms in an ecosystem. Biodiversity is among those things that decide on an ecosystem’s health and stability. Ecosystems with high biodiversity can more easily resist disturbances and recover them. Ecosystems provide various services useful to people: clean air and water, fertile soil, pollination of crops, and regulation of climate.

Among the numerous ecosystems that are present are forests, grasslands, wetlands, and oceans-they all stand out in their characteristics and functions. However, the majority of ecosystems under danger from human activities include deforestation, pollution, and climate change. The most important goals of conservation are to preserve and restore the ecosystem through practices that can balance human needs with environmental health.
