How did this affect the kelp forest?

Strong storms and changing water temperatures can cause changes in kelp forest communities. Human activities also impact the health of kelp forests through coastal development, sedimentation, pollution, and fishing. Removing predators while fishing can alter the food chain.

How do abiotic factors affect kelp?

Abiotic Factors that Affect Kelp Health, Density, and Population. Not unlike terrestrial plants, kelp requires nutrients such as Nitrogen and Phosphorus to grow and reproduce. Seasonal differences in strength of coastal upwelling results in natural variations in nutrient concentrations.

How do sea otters maintain kelp forests?

Sea otters maintain the balance of kelp forest ecosystems by controlling populations of sea urchins, which are voracious kelp grazers.

How do the populations of sea otters urchins and kelp affect each other?

relationship because both species benefit from the interaction. The sea otters help the kelp by eating the sea urchins because if there is too big of a population of sea urchins the kelp is endangered. The kelp in return provides and anchors for the sea otters while they are sleeping and doing daily activities.

How does a seaweed adapt to the sea?

Fronds of seaweeds are very tough, and this is helpful for the plant’s survival. This toughness allows the seaweed to avoid being torn by strong ocean waves. It also helps the seaweed keep water inside and not be dried out completely by the sun.

How does coastal development affect kelp forests?

Strong storms and changing water temperatures can cause changes in kelp forest communities. Human activities also impact the health of kelp forests through coastal development, sedimentation, pollution, and fishing. Removing predators while fishing can alter the food chain.

How does global warming affect kelp?

The disintegration of Northern California kelp forests, which grow along rocky coastlines in cool, clear water up to 100 feet deep, is a case study of how global warming triggers cascading effects. Oceans have absorbed about 93 percent of the heat trapped by industrial greenhouse gas pollution.

How does kelp affect ph levels?

Kelp and other seaweeds are ecosystem engineers that shape their physical and chemical surroundings. They soak up CO2 during the day through photosynthesis and thereby temporarily increase the pH level of seawater.

How does kelp get its nutrients?

Since the giant kelp is not a plant, it does not have roots. Instead, it obtains all of the necessary nutrients directly from the water and is attached to the rocky bottom by a structure known as a holdfast.

How does kelp influence biodiversity?

Giant kelp structure indirectly increases diversity by shading out understory algae that compete with stationary invertebrates. With more food available, the diversity of mobile predators increases.

How does kelp prevent erosion?

Through photosynthesis, kelp forests boost oxygen levels in the ocean while helping protect the coast from erosion by reducing the speed and size of waves.

How does low oxygen affect kelp?

When low-oxygen events occur, Leary will be able to track their movements through the kelp forest. … So after low-oxygen waves move through the kelp forest, they may leave pockets of hypoxic water along the bottom, altering and compressing fish habitats.

How does ocean acidification affect sea urchins?

Ocean acidification could interfere with the urchins’ ability to transform calcium, magnesium and other minerals from seawater into their “tests” (the white shell left when the animal dies), spines and teeth.

How does orca affect sea urchins?

Killer Whales Have Begun Preying On Sea Otters, Causing Disruption Of Coastal Ecosystems In Western Alaska. Summary: … The decline in sea otters has allowed their primary prey, sea urchins, to increase in number and strip coastal kelp forests over large areas.

How does orcas affect sea urchins?

Killer Whales Have Begun Preying On Sea Otters, Causing Disruption Of Coastal Ecosystems In Western Alaska. Summary: … The decline in sea otters has allowed their primary prey, sea urchins, to increase in number and strip coastal kelp forests over large areas.

How does rising co2 affect kelp?

As more carbon dioxide fills the air, more of the gas dissolves into seawater, making the ocean more acidic and threatening marine organisms. Giant kelp may offer a local solution. As kelp grows, it captures carbon from the water and produces oxygen, possibly removing enough carbon dioxide to relieve acidification.

How does seaweed affect the ocean?

Seaweeds buffer against ocean acidification, dampen wave action and reduce coastal erosion, and clean up waterways by absorbing excess nutrients from wastewater.

How does sedimentation affect kelp forests?

Increased seawater turbidity and/or sediments can impact marine kelp communities either by indirectly reducing sunlight or by the direct physical influence of the particulate matter.

Is kelp an abiotic or biotic factor?

Is kelp biotic or abiotic? Kelp Forest–Aquatic Biology. Abiotic factors are a major part of the kelp forest and allow it to live.

What animal eats giant kelp?

Sea otters play a particularly important role in the health of the bay’s kelp forests; without them, sea urchins — which normally eat pieces of kelp that fall to the seafloor — will feed on the stripes of giant kelp plants and can completely destroy a kelp bed.

What animals in the sea eat kelp?

What creatures eat kelp? Invertebrates that eat kelp include snails and shellfish such as crabs, sea urchins and abalone. These shellfish are themselves eaten by other creatures. For instance, in the Pacific Ocean off the West Coast of the United States, sea otters eat a lot of abalone.

What are the adaptations for kelp?

Although kelps resemble land plants, they are uniquely adapted to life in cool, clear, moving water. They depend on moving water to provide a steady supply of nutrients for photosynthesis. As water flows by the blades, their serrated edges help to increase water mixing.

What are threats to kelp forests?

What threats do kelp forests face? Unfortunately, kelp forests today face a variety of threats, such as commercial kelp harvesting, pollution, and climate change, which exacerbates El Niño southern oscillation (ENSO) events and negatively impacts kelp reproduction and survival.
