Which human activity is most likely to be a major threat to marine systems?

Global warming is causing sea levels to rise threatening coastal population centers. Many pesticides and nutrients used in agriculture end up in the coastal waters resulting in oxygen depletion that kills marine plants and shellfish. Factories and industrial plants discharge sewage and other runoff into the oceans.

Which of the following are the two greatest long term threats to coral reefs choose two?

Increased ocean temperatures and changing ocean chemistry are the greatest global threats to coral reef ecosystems. These threats are caused by warmer atmospheric temperatures and increasing levels of carbon dioxide in seawater.

What are the 4 types of coral reefs?

Scientists generally agree on four different coral reef classifications: fringing reefs barrier reefs atolls and patch reefs.

  • Fringing reefs grow near the coastline around islands and continents. …
  • Barrier reefs also parallel the coastline but are separated by deeper wider lagoons.

What are the two main types of freshwater wetlands quizlet?

the three most common types of freshwater wetlands are marshes swamps and bogs. what are marshes? marshes are usually grassy areas covered up by shallow water or streams. They have many cattails and tall grasses.

What is terrestrial ecosystem and its types?

A terrestrial ecosystem is a land-based community of organisms and the interactions of biotic and abiotic components in a given area. Examples of terrestrial ecosystems include the tundra taigas temperate deciduous forests tropical rainforests grasslands and deserts.

What are the 3 types of aquatic biomes?


  • Aquatic biomes can be classified based on the amount of salt in the water.
  • Freshwater biomes have less than 1% salt and are typical of ponds and lakes streams and rivers and wetlands.
  • Marine biomes include the oceans coral reefs and estuaries.

What name is given to the factors that determine the types and numbers of organisms in an ecosystem Site 1?

A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem examples might include aquatic plants fish amphibians and algae. Biotic and abiotic factors work together to create a unique ecosystem.

What are the three types of aquatic organism describe each?

Aquatic organisms generally fall into three broad groups: plankton nekton and benthos. They vary in how they move and where they live. Plankton are tiny aquatic organisms that cannot move on their own. They live in the photic zone.

What type of ecosystem is a lake?

Pond and lake ecosystems are a prime example of lentic ecosystems. Lentic refers to stationary or relatively still water from the Latin lentus which means sluggish. A typical lake has distinct zones of biological communities linked to the physical structure of the lake.

What factors help us categorize aquatic biomes?

Aquatic biomes can be generally classified based on the amount of salt in the water. Freshwater biomes have less than 1% salt and are typical of ponds and lakes streams and rivers and wetlands. Marine biomes have more salt and are characteristic of the oceans coral reefs and estuaries.

How are organisms in an aquatic ecosystem grouped?

Organisms that live in aquatic ecosystems are grouped by their location and by their adaptations. Three groups of aquatic organisms include plankton nekton and benthos.

Which of the following is classified as freshwater aquatic life zone?

A. Freshwater life zones include standing (lentic) bodies—such as lakes ponds and wetlands—and flowing (lotic) systems such as streams and rivers. B. Lakes are large natural bodies of standing water found in depressions.

Oysters Sea Stars And Lobsters Would Be Considered What Type Of Organism??

Macrobenthos are organisms that are larger than one millimeter like oysters starfish lobsters sea urchins shrimp crabs and coral. Meiobenthos are between one tenth and one millimeter in size. Organisms in this group include diatoms and sea worms.

Is the fresh water standing type of ecosystem?

The freshwater ecosystems are generally classified into two major groups as lentic and lotic ecosystems. The term Lentic ecosystems is given to standing water bodies or still water bodies. The LENTIC Ecosystems includes all standing water bodies like Lakes ponds swamps or bogs.

What are strongly Swimming consumers?

these organisms are strong swimming consumers such as fish turtles and whales. these are organisms that are bottom-dwellers such as oysters and sea stars which anchor themselves to ocean bottom structures clams and worms which burrow into the sand or mud and lobsters and crabs which walk about on the sea floor.

Sea Stars

What is aquatic food organisms?

Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton small fish and crustaceans. Primary consumers are in turn eaten by fish small sharks corals and baleen whales.

What are the three common types of freshwater wetlands?

Most scientists consider swamps marshes and bogs to be the three major kinds of wetlands. A swamp is a wetland permanently saturated with water and dominated by trees.

What are the two main type of freshwater wetlands?

There are 4 main types of Freshwater Wetlands in North America Ponds Marshes Swamps and Peat bogs. A Marsh is usually found near a river lake or tidal waters.

What are the major types of freshwater systems?

There are three main types of freshwater biomes: ponds and lakes streams and rivers and wetlands. We’ll go into the details of each below. Ponds and lakes are often called lentic ecosystems. This means that they have still or standing waters not moving like rivers or streams.

How do human activities affect species diversity?

How do human activities affect species diversity? Over-exploitation pollution and habitat conversion are the main threats to species diversity. They cause a gradual loss of species on local regional and global levels. Additionally the introduction of species into new ecosystems destroys natural balance.

How many different species live in coral reefs?

Scientists believe that more than a million species around the world live on coral reefs. At any one reef thousands of species can be collected or observed living there.

What are the three types of coral reefs?

The three main types of coral reefs are fringing barrier and atoll. Schools of colorful pennantfish pyramid and milletseed butterflyfish live on an atoll reef in the Northwestern Hawaiian Islands. The most common type of reef is the fringing reef. This type of reef grows seaward directly from the shore. See also what is a valley glacier
