Landscapes - ecosystemchoose a jigsaw puzzle to solve

An ecosystem is a community made up of living organisms and nonliving components such as air , water and mineral soil . Ecosystems may be studied either as contingent collections of plants and animals , or as structured systems and communities that are governed by general rules. The biotic and abiotic components interact through nutrient cycles and energy flows. Ecosystems include a network of interactions among organisms, and between organisms and their environment. Ecosystems can be of any size but one ecosystem has a specific, limited space . Some scientists view the entire planet as one ecosystem. Energy , water , nitrogen and soil minerals are other essential abiotic components of an ecosystem. The energy that flows through ecosystems comes primarily from the sun , through photosynthesis. Photosynthesis also captures carbon dioxide from the atmosphere . Animals also play an important role in the movement of matter and energy through ecoystems.
