How deep is the oceans photic zone?
Photic - light; photic zone - light falling zone.
Depth of photic zone refers to the distance travelled by sunlight in to the depth of the water and enable photosynthesis. It is measured using SECCHI DISC or photometer.
Depth of photic zone is influenced by turbidity.
It includes atmosphere-water surface to the depth where the total penetrating light intensity falls by 1%.
This zone is a zone of productivity.
Which are the two biomes with the most biodiversity?
The Main Water Biome & the Tropical Rain Forest have the greatest biodiversity, Rain Forest being the greatest. All this means is that these two biomes have a great amount of plant and animal species.
If you were a plant which zone would be most difficult to live in?
As a plant, the extreme conditions in zones characterized by hot deserts or frigid polar regions would be the most challenging to thrive in. These zones often have limited water availability, high temperatures, or extreme cold, presenting significant obstacles for plant survival and growth.
How can overfishing lead to ecosystem collapse?
Ecosystems are an integrated process that requires each part to be present to allow the whole system to operate correctly. This is similar to a car engine that requires all of its parts to work - "over removing" the crankshaft affects the whole engine.In the case of fish they are both consumers and consumed. Fish eat smaller plants and animals that would overpopulate their niche in the ecology if not removed. This ould cause a depletion of the smaller plants and animals they feed on crating a barren base ecology. As fish are consumed, the animals they feed would be starved for food and either die out or move to other locations. They might also switch to less nutritious food or to species that are not as numerous and deplete their numbers.
It doesn't stop there. Bears, as an example, eat salmon. They then wander through the woods where their faces provide nutrients for trees. The trees provide ecologies for a wide range of animals and have other functions like soil building with their leaves or needles and soil stabilization with their roots. Therefor - no salmon, no bears, no healthy trees, no birds and squirrels, no control of erosion, eroded soil fills the streams and the hydrogeology of the ecosystem changes.
- The water table is located at the top of the zone of saturation, where soil and rock are completely saturated with water.
- It is not generally found under the zone of saturation.
- The water table is typically above the layer of bedrock.
- It is usually located above the layer of bedrock, not below it.
Why is the great barrier reef so important to us?
The Great Barrier Reef is important because it is the largest coral reef system in the world, providing habitat for numerous marine species. It also supports tourism, fishing, and protects coastlines from erosion. Additionally, the reef is crucial for scientific research and understanding the impacts of climate change on marine ecosystems.
What would happen if the climate conditions change in the great barrier reef?
Most island of the Great Barrier Reef are very little above seal level, thus would be swamped by a rapid rise in sea level brought about by glaciers melting. The same fate awaits the Maldives and many island groups, also countries like Bangladesh.
If you were in the Great Barrier Reef what would you be wearing?
If I were in the Great Barrier Reef, I would be wearing a swimsuit, rash guard to protect against the sun, reef-safe sunscreen, and dive or snorkeling gear if I plan to explore underwater. It's important to be comfortable in the water while also protecting yourself from the sun and potential hazards.
Barnacle fish mainly feed on plankton, algae, and small invertebrates. They use their specialized mouthparts to scrape food particles from surfaces or filter them from the water. Some species may also scavenge on organic debris.
What are the average yearly temperatures for the shoreline biome?
There is no specific temperature it depends on the location and weather, the same as anywhere else.
Temperature variations between night and day tend to be fairly limited during summer with a difference that can reach 19 degrees Fahrenheit, and fairly limited during winter with an average difference of 12 degrees Fahrenheit.DOGS RULE AND THE SECOND ONE IS RIGHT NOT THE FIRST ONE
Why do conditions vary in different zones of a rocky shore?
They do for many reasons, one is that tides cause diffeen velocitys of growth compared to normal sea level changes, another is that my bum is very sore due to heat rash and i have to put fatty ointment on i because the doc said it was the right thing to do...
Ediacara life-forms are a group of soft-bodied, early multicellular organisms that existed in the Ediacaran Period, around 635-541 million years ago. They were some of the earliest complex organisms on Earth and existed prior to the Cambrian explosion. Ediacara biota are known for their diverse body plans and unique shapes.
Topaz has a density of 3.4-3.6 which is much more than water has (1.0) , so topaz sinks in water.
What is the movement of water within the surf zone that parallels the shore?
Longshore currents are the movement of water within the surf zone that parallels the shore. These currents are responsible for transporting sand and sediment along the coastline and can be influenced by wave direction and beach topography. Longshore currents can be strong and pose a hazard to swimmers and surfers.
How many life forms are there?
It is estimated that there are around 8.7 million species of life forms on Earth, but the actual number could be much higher. The majority of these species are still undiscovered, especially in habitats like the deep sea and tropical rainforests.
What city is the Great Barrier Reef located?
Because the Great Barrier Reef extends for 2000 km up the Queensland coast, there are several cities close to the reef. A large city which is closest to where the reef comes in nearest the coast is Cairns.
Townsville is a large city along the coast, but the reef is not as accessible and close to shore from there. The southern end of the Great Barrier Reef is around 75km northwest of the port city of Gladstone.
Brisbane is the nearest capital city to the Reef, but it is about 530km from the southern end.
Contrary to popular overseas opinion, Sydney is nowhere near the Great Barrier Reef, as it is 930 kilometres south of Brisbane.
What is an octopus locomotion?
It uses its 8 tentacles and thrashes them to propel through the water, like if you swam moving your arms to the sides
What types of rock are found in the Great Barrier Reef?
The Great Barrier Reef is primarily composed of coral, which is formed by the accumulation of calcium carbonate skeletons from coral polyps. Additionally, there are some areas where sediments and sandstones can be found.
What are soe major breakthroughs in marine biology?
The Alvin sailed underwater in 1977, all the way to the ocean floor.The sun was not shining there because it was so deep. Marine Biologists were shocked to see tubeworms plankton and more life.They then discovered that the solar energy was from the hot springs! Hope this helped (; N.E.B.
The permanetly dark zone below the photic zone is called the?
The permanently dark zone below the photic zone is called the aphotic zone. In this region, sunlight is unable to penetrate deep enough for photosynthesis to occur, resulting in a lack of primary production by plants. Organisms in this zone rely on alternative energy sources, such as detritus and chemosynthesis.
All the organism have adaptations, for example humans have teeth to eat, lions have claws to tear their prey. So if you want to know some kind of creatures adaptations, please write it on the question.
Can industrial thermal run off be used?
Yes, industrial thermal runoff can potentially be used for various purposes such as heating buildings, generating electricity through steam turbines, or even for industrial processes that require heat. However, it must be carefully managed to prevent environmental impact and ensure efficiency in its use.
What layer of the ocean do plants grow?
Plants in the ocean typically grow in the euphotic zone, which is the upper layer where sunlight penetrates and allows for photosynthesis to occur. This zone usually extends to around 200 meters deep, but can vary based on water clarity and other factors.
