MARINE ECOLOGYNOTES

What do you mean by marine ecology?
Marine ecology is the study of living things in the ocean and how they interact with their environment.
It is an interdisciplinary science that combines biology with physical sciences (e.g. geology, chemistry, oceanography, geophysics, statistics).
What are the 4 types of marine ecosystems?
The number of marine ecosystems is actively debated.
Although there is some disagreement, several types of marine ecosystems are largely agreed on: estuaries, salt marshes, mangrove forests, coral reefs, the open ocean, and the deep-sea ocean.
An estuary is a coastal zone where oceans meet rivers.
What are the principles of marine ecology?
The four ecological principles – maintaining or restoring (1) native species diversity, (2) habitat diversity and heterogeneity, (3) key species, and (4) connectivity - must form the foundation of any ecosystem based planning efforts.
Healthy marine ecosystems are important to society as they provide services such as food security, animal feeds, and raw materials for pharmaceuticals, building materials for coral and sand, and nature protection against dangers such as coastal erosion and floods.
