Why does a marine ecosystems are important?

Upvote4 Downvote1

The oceans are a significant source of oxygen for our planet and are instrumental in the capture and storage of carbon dioxide. Marine species provide important ecosystem services such as the provision of food, medicines, and livelihoods. They also support tourism and recreational activities around the world.

Considering this, what are the five main marine ecosystems?

Marine ecosystems include: the abyssal plain (areas like deep sea coral, whale falls, and brine pools), polar regions such as the Antarctic and Arctic, coral reefs, the deep sea (such as the community found in the abyssal water column), hydrothermal vents, kelp forests, mangroves, the open ocean, rocky shores, salt

What are the characteristics of the marine ecosystem?

Specific marine ecosystems such as coral reefs, estuaries, salt mashes, mangrove forests are found throughout the world, but are characteristic of certain areas, depending on climate, geography, water temperature, and other physical factors.

What kind of animals live in the marine ecosystem?

Here are just a few of the animals that you will find in the marine biome:

Fish - Sharks, swordfish, tuna, clown fish, grouper, stingray, flatfish, eels, rockfish, seahorse, sunfish mola, and gars.
Marine mammals - Blue whales, seals, walruses, dolphins, manatees, and otters.

How many species of marine life are there?

Between 700,000 and one million species live in the world's oceans, according to a thorough new analysis, which also estimated that between one-third and two-thirds of those species have yet to be named and described.

3

Which marine ecosystem has the highest biodiversity?

Biodiversity is the variety of living species that can be found in a particular place—region, ecosystem, planet, etc. Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest.

What are the characteristics of the marine ecosystem?

Specific marine ecosystems such as coral reefs, estuaries, salt mashes, mangrove forests are found throughout the world, but are characteristic of certain areas, depending on climate, geography, water temperature, and other physical factors.

5

What is the definition of marine biodiversity?

Marine biodiversity therefore refers to the species richness and abundance in the world's oceans and seas. And since the world is covered with approximately 70% water, the amount of life in the oceans is enormous.

Fish - Sharks, swordfish, tuna, clown fish, grouper, stingray, flatfish, eels, rockfish, seahorse, sunfish mola, and gars.
Marine mammals - Blue whales, seals, walruses, dolphins, manatees, and otters.

What is the definition of marine resources?

They include a huge number of things biological diversity, fish and seafood supplies, oil gas, minerals, sand gravel, renewable energy resources, tourism potential, unique ecosystems like coral reefs under the broadest definition term, marine resources are that plants, animals humans need for life originate in ocean.

8

Why is sea life important?

Why are oceans important? Oceans are the lifeblood of planet Earth and humankind. They flow over nearly three-quarters of our planet, and hold 97% of the planet's water. They produce more than half of the oxygen in the atmosphere, and absorb the most carbon from it.

9

What is the biodiversity of the ocean?

The variability among living organisms from all sources, including, inter alia [among other things], terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part: this includes diversity within species, between species and of ecosystems.

10

What is the marine environment?

Marine life depends in some way on the saltwater that is in the sea (the term marine comes from the Latin mare, meaning sea or ocean). A habitat is an ecological or environmental area inhabited by one or more living species. Marine habitats can be divided into coastal and open ocean habitats.

11

How does climate change affect the biodiversity of a region?

Healthy ecosystems and rich biodiversity are fundamental to life on our planet. Climate change is affecting the habitats of several species, which must either adapt or migrate to areas with more favourable conditions. Even small changes in average temperatures can have a significant effect upon ecosystems.

12

What are the factors of biodiversity?

Natural or human-induced factors that directly or indirectly cause a change in biodiversity are referred to as drivers. Direct drivers that explicitly influence ecosystem processes. include land use change, climate change, invasive species, overexploitation, and pollution.

13

Why is it important to have species diversity in the oceans?

Why is marine biodiversity important? Every ecosystem performs certain functions that are critically important for organisms. They thereby ensure that the structure-forming plants are not smothered, and are allowed to grow – that is their contribution to the ecosystem.

14

What is the meaning of marine life?

Marine life is concerned with the plants, animals and other organisms that live in the ocean. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.

15

Where are benthos Nekton and plankton organisms found?

Examples include microscopic foraminifera, coccolithophores, radiolarian, diatoms, dinoflagellates, and the larvae of many marine animals, such as crabs, fish, and sea stars – as well as larger organisms like floating sargasssum weed and jellyfish. Benthos are organisms that live on or in the seafloor sediment.

16

What is the definition of a marine ecosystem?

Marine ecosystems are among the largest of Earth's aquatic ecosystems. Examples include salt marshes, intertidal zones, estuaries, lagoons, mangroves, coral reefs, the deep sea, and the sea floor. They can be contrasted with freshwater ecosystems, which have a lower salt content.

17

What is the benthic environment?

The Benthic Community is made up of organisms that live in and on the bottom of the ocean floor. Benthos include worms, clams, crabs, lobsters, sponges, and other tiny organisms that live in the bottom sediments. Benthos are divided into two groups, the filter feeders and the deposit feeders.

18

Are jelly fish plankton?

Jellyfish are a type of zooplankton that both drift in the ocean and have some swimming ability. Hundreds of jellyfish species live in every part of the ocean and belong to the same animal group as corals and sea anemones.
