What makes kelp forests unique?
They grow in dense groupings much like a forest on land. These underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species. Kelp forests harbor a greater variety and higher diversity of plants and animals than almost any other ocean community.
Why is kelp important?
Because kelps are primary producers that modify the environment to create suitable habitat for a great diversity of species, they are known as foundational species. Kelp forests are also among the most productive ecosystems in the world, allowing them to support the diverse assemblage of life that inhibits them.
How do kelp forests grow?
Kelp thrives in cold, nutrient-rich waters. Because kelp attaches to the seafloor and eventually grows to the water's surface and relies on sunlight to generate food and energy, kelp forests are always coastal and require shallow, relatively clear water.
Are kelp forests endangered?
The Australian government now lists giant kelp forests as an endangered ecological community.
What is the relationship between temperature and kelp productivity?
Kelp forests grow best in nutrient-rich, clear waters whose temperatures are between 42–72 degrees F (5–20 degrees C). The water must be clear so that sunlight can reach the ocean floor where the kelp life begins. If the water is too warm (warmer than 20 degrees), the kelp does not thrive as well.
How does kelp grow so fast?
Giant kelp often grows in turbulent water, which brings renewed supplies of nutrients. This allows the kelp to grow to a possible height of 175 feet (53.4 m). The stemlike stipes are tough but flexible, allowing the kelp to sway in ocean currents.
How does kelp benefit the environment?
Kelp and other seaweeds are an important part of the marine ecosystem. Not only do they provide habitat and a source of food for a wide variety of sea life, kelp beds also disperse wave energy to protect shorelines from erosion. Sustainable harvest practices are critical to preserving wild kelp beds.
How does the presence of kelp influence water oxygen levels?
Kelp biomass is concentrated near the surface in the canopy region, so an increase in kelp photosynthesis can further elevate dissolved oxygen and pH in surface waters relative to deeper water (Frieder et al., 2012; Koweek et al., 2017).
How does kelp get water?
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.
Where is kelp found in Minecraft?
ocean biomes Kelp naturally generates in any ocean biomes (except in frozen, deep frozen and warm), near and around seagrass. Each chunk has 1⁄18 chance to generate a random patch of kelp.
How does climate change affect kelp?
Ocean heat waves suppress the upwelling of the cold, oxygenated and nutrient-rich water that kelp needs to thrive, so it's common for it to die back periodically, when hotter conditions occur.
How does water temperature affect kelp?
As the temperature of the water goes up, the amount and spatial extent of the kelp goes down. These changes could result in dramatic habitat loss leading to reduced ecosystem productivity and the extinction of many invertebrate species.
What is the relationship between oxygen and kelp productivity?
Despite their short lives by plant standards, kelps siphon huge amounts of carbon from the atmosphere—what scientists call “primary productivity.” They take carbon dioxide from the air and turn it into sugar fuel with the help of sunlight and water, releasing oxygen back into the air.
Do kelp forests have high productivity?
Aquatic kelp forests are considered to be some of the most productive ecosystems on the planet. These giant pillars of seaweed, commonly found along the Pacific coast of North America, provide food and shelter for thousands of marine species.
What factors affect kelp?

- Temperature. …
- Light. …
- Strength of Currents. …

What does kelp do for the water?
During photosynthesis, kelps take carbon dioxide out of seawater which drives pH up in the local environment.
How do you make green dye on Minecraft?
Unlike most other dyes, green dye in Minecraft Java, Bedrock, and Education editions do not have a typical crafting recipe. Instead, you need to smelt cactus in a furnace. Cactuses are mainly found in desert and badlands biomes. You will receive one green dye for every block of cactus you smelt in return.
What is smoker in Minecraft?
A smoker minecraft is a block that can be used to cook food items, like furnaces, but it takes less time than the furnace. It can also serve as the butcher's job site look block. If you use it on something other than food items, it won't work.
What has caused a reduction in kelp in the ocean?
Second, sea star wasting disease is killing the main predator of sea urchins, the sunflower sea star. Since their only predator in the ecosystem is dying, sea urchin numbers are increasing dramatically. Sea urchins feed on kelp, and this has ultimately led to a decrease in kelp forests.
How does ocean pollution affect kelp forests?
Non-point and point source pollution including sewage, industrial disposal, and coastal runoff might contribute to kelp forest degradation. For instance, high sedimentation from coastal run-off may bury new plant shoots.
How does oxygen affect kelp productivity?
As well as photosynthesizing, kelps and macroalgae also respire, which requires oxygen. Thus, deoxygenation may impact net primary production (NPP), which supplies organic matter to support food webs and ecosystems.
What is the relationship between water clarity and urchin survival?
CLEANLINESS. Sea urchins are used as indicator organisms in public aquariums to determine if the system is functioning properly. This is because they are very "picky" about water quality. If the water is contaminated, the sea urchins will be the first to show signs of stress, spines laying down or falling off.
How does oxygen and carbon dioxide 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.
What are the factors that affect primary productivity?
Solution : Factors affecting primary productivity: the Primary productivity depends upon plant species of an area, their photosynthetic capacity, availability of nutrients, solar radiation, precipitation, soil type, topographic factors (altitude, latitude, direction) and other environmental factors.
What are the factors affecting primary productivity?

What structural feature allows kelp to absorb more nutrients from the water?
Last but not least is the holdfast. Plants have roots which keep them grounded and allow for the absorption of nutrients, but kelp is different. The kelp grows in rocky areas, so the holdfast is used as the anchor for the kelp on these surfaces.
Can you bonemeal cactus?
Bone meal does not work on cacti to speed their growth. A cactus does not need light to grow and is non-flammable.
How do you make lapis lazuli in Minecraft?
Players can find lapis lazuli ores on the surface of caves and ravines. These ores can generate in veins of one to eight. An easy way to find lapis lazuli in Minecraft is to explore caves and ravines under Y level 32. When mining lapis lazuli ores, use a fortune III pickaxe to get a lot of lapis lazuli.
What villager uses the blast furnace?
armorer villagers Blast furnaces now serve as armorer villagers' job site block.
How do you get Fletcher?
The best way to transform a jobless Villager into a Fletcher is to corner one in their home, or another cramped location, and seal up all possible exits from within. Then, place the Fletching Table anywhere and wait until the jobless Villager interacts with it.
