If algae populations continue to decline, the great barrier reef food web would crash.
Despite being a biodiverse and productive environment, coral reefs are in danger due to regional and global factors. Coral reef destruction as a result is endangering coastal food supplies and livelihoods. Climate predictions indicate that coral reefs would continue to experience significant changes even if the Paris Agreement's (Dec 2015) objectives are successfully carried out. Modified food webs, changes in community structure, decreased habitat complexity, decreased fecundity and recruitment, adjustments to fisheries productivity/opportunity, and a shift in some ecosystems' carbonate budgets toward the dissolution and erosion of calcium carbonate stocks are just a few examples of ecological changes.

What is the Carboniferous period also known as?
Answer:
The period is sometimes called the Age of Amphibians, during which amphibians became dominant land vertebrates and diversified into many forms including lizard-like, snake-like, and crocodile-like.
Explanation:
The "Carboniferous Period" is sometimes referred to as the "Age Of Amphibians".
Describe amphibians.Amphibians are a group of small animals that need water or a damp environment to survive.
These species include frogs, toads, salamanders, and newts. Each creature has incredibly thin skin that enables breathing and water absorption.
Furthermore, amphibians have special skin glands that produce useful proteins. Some allow the animal to take in or release gases like carbon dioxide, oxygen, and water. Others fight off fungal or bacterial infections. Each species also employs one or more for defense.
To warn potential predators, the most deadly frogs are also the most colorful. Curare, for instance, is found in the skin of colorful poison dart frogs. Another distinctive characteristic of most amphibians is their life cycle of egg-larva-adult.

What Natural vegetation region is best for agriculture
The natural vegetation region that is best for agriculture is the Grassland vegetation region.
What vegetation regions are good for agriculture?There are five main vegetation regions which are forests, deserts, tundra, grassland, and the places covered with ice sheets. Of these five, only 2 are suitable for agriculture and they are the grassland vegetation region, and the forest vegetation region.
The grassland vegetation region is most often used for agriculture because it is found more abundantly than the forest vegetation. There is also the fact that it is easy to harvest and easy to plant on because it doesn't have as many trees as the forest vegetation region.
Using a grassland vegetation region is also more environmentally friendly because less trees are cut as would have been done in the forest region. Overall, the grassland vegetation region is best for agriculture and the environment.

Are you referring to above the surface of the ocean or below the surface of the ocean? But either way it is completely dark at night in the ocean, and without any source of light or any glow from the moonlight, it would be near pitch black above or below the surface of the ocean.
The surface of the ocean may reflect light radiating from the moon, and therefore illuminating the surface of the ocean providing visibility depending on the phase of the moon, brightest during the full moon.
But during the day, the glow of light from the sun may travel as far as 1000 meters deep into the ocean, although light still travels beyond 200 meters and up to 1000 meters but its intensity is greatly reduced making it nearly invisible to the eye.
Euphotic (sunlight zone) 0 - 200 meters deep is penetrable by light.
Dysphotic (twilight zone) 200 - 1000 meters is barely penetrable by light making it darker as the depth increases.

The ocean's surface may reflect moonlight, brightening it and improving vision, depending on the moon's phase. The full moon is when this is the brightest.
During the day, light can travel up to 1000 meters and beyond 200 meters, but it is much less strong and is essentially imperceptible to the human eye. The sun's light can reach sea depths of up to 1000 meters.

the expansion of deeply buried rocks after they are exposed by erosion causes the formation of?
Using the concepts of rocks, we got that the expansion of deeply buried rocks after they are exposed by erosion causes the formation of Fractures.
Fractures along which the rock has slipped relative to the other side are called faults, whereas fractures that are the simple cracks where the rock has pulled apart by the small amount are joints. Any fracture or system of fractures along which the Earth moves is known as a fault. Faults allow the blocks to move relative to each other which actually results to an earthquake.
When deeply buried rocks are uncovered by the erosion, the removal of weight allows them to relax and expand. Produces fractures and it increases in porosity. This stress-relaxation process actually reduces the strength of rocks, opening up passageways/storage places for the water to attack and further weaken the rocks.
Hence, the expansion of deeply buried rocks after they are exposed by erosion causes the formation of Fractures which reduce the strength of the rock.

Which of the following situations would result in a relatively higher regional elevation?
A. Cool, dense oceanic-crust lithosphere far away from the mid-ocean ridge
B. Dense lithosphere replaced by less dense asthensophere
C. Subduction of oceanic crust lithosphere in a trench system
D. A region with thin lithosphere (such as the mid-ocean ridge)
A location with a thinner lithosphere will have a comparatively higher regional elevation as the thick lithosphere is replaced by the less dense asthenosphere.
When the lithosphere in a certain area is heated, it expands and becomes less dense, elevating the area as a result. Because less thick asthenosphere is replacing more dense lithosphere in this instance, thinner lithosphere likewise produces greater heights.
Regional heights are largely governed by crustal thickness, although they can also be impacted by the upper mantle's material composition, temperature, and density.
Different geologic histories of different places are reflected in disparities in crustal thickness. The highest point on Earth is Mount Everest's summit, which is located in both China and Nepal.

A lateral moraine is a result of: glaciers scrape along valley walls, knocking rock loose.
The correct option is e.
Landforms called moraines are made of glacial till, which is primarily deposited by glacial ice. As the ice melts, it leaves behind heaps of sharp-crested boulders and other debris that have been carried by the glacier. They only develop in a glacier's ablation zone.
A lateral moraine develops on a glacier's flanks. The glacier loosen rock and dirt from both sides of its path as it moves along.
