Ocean Zones
How much of the planets water is found In the biome
97%
What are plankton?
Organisms that float with weak swimming abilities
What is the photic zone?
Light
Biotic sources?
Living organisms in the biosphere
What are major oceans in the world?
Pacific, Atlantic, Indian, Southern and Arctic Ocean’s
T or F Biologically this is the planets most important biome
True
What is zooplankton
Animal plankton
Describe the process of marine primary production.
Marine primary production is the synthesis of organic compounds from inorganic substances, primarily through photosynthesis by phytoplankton and algae. These primary producers convert carbon dioxide and nutrients into organic matter, providing the foundation of the marine food web
What are some marine sources?
Fish or coral, minerals oil and gas
Define Marine biodiversity
Marine biodiversity refers to the variety and variability of life forms within marine ecosystems, including the diversity of species, genetic diversity, and ecosystem diversity.
Explain the concept of ocean acidification?
Ocean acidification is the process by which the pH of the ocean decreases due to the absorption of carbon dioxide from the atmosphere, leading to a decrease in the availability of carbonate ions
What are the differences between plankton, nekton, and benthos
Plankton are tiny organisms that drift in the water and cannot swim against currents. Nekton are larger, free-swimming organisms such as fish, mammals, and squid. Benthos are organisms that live on or in the ocean floor, including algae, sponges, and bottom-dwelling fish.
What are the main types of marine ecosystems?
Marine ecosystems include coral reefs, mangrove forests, seagrass beds, kelp forests, open ocean (pelagic zone), intertidal zones, and deep-sea habitats.
What are some conservation strategies to protect marine ecosystems
Conservation strategies include the establishment of marine protected areas, sustainable fisheries management, reducing pollution from land-based sources, addressing climate change through carbon emissions reduction, promoting sustainable seafood consumption, and raising awareness about the importance of marine ecosystem
What is the biggest biome?
Marine
…… is the top layer of the ocean
Sunlit zone
What are some adaptations that marine organisms have developed to survive in their environment?
Marine organisms have developed a variety of adaptations to survive in their environment, including streamlined bodies for efficient swimming, salt glands to excrete excess salt, camouflage and mimicry for protection, bioluminescence for communication and camouflage, and specialized feeding structures
What is a marine food web, and how does it function?
A marine food web is a network of interconnected food chains, depicting the flow of energy and nutrients through marine ecosystems. Producers (such as phytoplankton and algae) are consumed by primary consumers (herbivores), which are in turn eaten by secondary consumers (carnivores), and so on. Decomposers break down organic matter, returning nutrients to the ecosystem
What is the importance of coral reefs and the threats they face
Coral reefs are incredibly biodiverse ecosystems that provide habitat for numerous species, protect coastlines from erosion, and support local economies through tourism and fishing. However, they face threats from climate change, ocean acidification, pollution, overfishing, and destructive fishing practices such as blast fishing and cyanide fishing
