PPT-EXPLORING MARINE ECOSYSTEMS

All ecosystems contain biotic and abiotic factors Biotic living features Abiotic nonliving physical features Relationship between biotic and abiotic factors is important to ecosystem health.

The Nation’s valuable ocean ecosystems are being disrupted by increasing global temperatures through the loss of iconic and highly valued habitats and changes in species composition and food web structure. Ecosystem disruption will intensify as ocean warming, acidification, deoxygenation, and other aspects of climate change increase. In the absence of significant reductions in carbon emissions, transformative impacts on ocean ecosystems cannot be avoided.. BY. . A.Swedha. Assistant Professor. Department of Microbiology.
