Look at the graph to the right. What does it show? Why do you think corals have declined since ? Gizmo Warm-up Coral reefs are some of the most diverse habitats on Earth, home to over a quarter of all marine species. In the Coral Reefs 1exploration, you will focus on the effects of environmental factors on Caribbean reefs. Click Advance year 10 times.

Look carefully at the composition of the reef over time. Do you see any major changes? Select the DATA tab. Check that Staghorn coral, Star coral, Sponges, and Algae are selected.

Coral Reef

Populations are given as a percentage of normal populations. Click Advance year 15 times. What do you notice about these populations? In a healthy reef, what are the values for Nutrient load, Water clarity, Coral cover, and the total number of fish species? Click Restart. Introduction: A healthy Caribbean reef is home to over 50 species of coral and over fish species.

In this simplified model, we only consider the interactions of ten important species. Question: How do different species interact in a healthy coral reef? For each organism, give its name and what it eats or how it obtains energy. How do you think corals would be affected by cloudy, muddy water? Their food supply would be low because the cloudy, muddy water would block the sun form reaching it Classify: A producer is an organism that makes its own energy, usually from sunlight.

A consumer is an organism that gets energy by feeding on other organisms. Which of the reef organisms in this Gizmo are producers? Which of the reef organisms are consumers. Check that Ocean conditions is selected on the dropdown menu.

Introduction: In recent decades, global climate change has altered ocean conditions in the Caribbean. Average surface temperatures have risen about 0. Many scientists think climate change will lead to stronger storms and may cause the ocean to be more acidic. Question: How are coral reefs affected by storms, high temperatures, and acidic water?

Predict: Coral reefs in the Caribbean are sometimes damaged by hurricanes.

Of the two types of coral shown, which do you think is more resistant to storm damage? What changes do you notice? Which organism was most hurt by increased storms? Click Return to original settings and Restart. The white corals you see have undergone coral bleaching. At high temperatures, corals may lose their zooxanthellae, causing corals to lose their color and their main source of food. Once bleaching occurs, the coral colony usually dies.Author: Created by EncounterEdu.

Created: Sep 19, Updated: Feb 4, This lesson will look at the impacts of coral reef destruction, categorising those impacts. We discover the impacts to different stake holders in Timor-Leste through watching videos. Students will then write a letter to their local MP informing them of the threats the coral reefs are facing and why they need protection.

This lesson is from the Coral Oceans Geograpy unit. The unit delivers a comprehensive understanding of coral reefs. Through the use of our exclusive galleries, videos and online resources, students will develop their knowledge and understanding of what coral reefs are, why they are important and how to protect them.

The unit includes challenging lessons on abiotic components such as the nutrient cycle and biotic factors such as food chains. To experience the full impact of this scheme of work it can be taught in advance of our annual Coral Live event. Read more. Report a problem.

Coral reefs provide food and shelter for fish and other animals. Normally, the Great Barrier Reef is bursting with life. This March, biologists made an alarming discovery: They found that 93 percent of the Great Barrier Reef is suffering from coral bleachingwhen the corals that make up a reef turn white.

These tiny sea creatures live in colonies. They build hard skeletons under themselves, forming reefs see How Corals Build Reefs. These structures provide food and shelter for fish and other animals. But recently, the reef has come under threat. So have others like it around the globe. Biologists made an alarming discovery this March. They found that 93 percent of the Great Barrier Reef is suffering from coral bleaching.

Bleaching happens when corals are exposed to water temperatures that are warmer than usual. Warmer water puts stress on corals. In response, they expel tiny plantlike organisms, called algaethat normally live inside their tissues and give them their color. The corals protect the algae, and the algae make food for the corals. Bleaching happens when water temperatures are warmer than usual.

In response, they push out algae that normally live inside their tissues. These tiny, plant-like organisms give corals their color. This relationship is an example of mutualism. The corals protect the algae. And the algae make food for the corals. Corals also capture prey. But scientists believe that algae provide corals with up to 90 percent of their energy. When temperatures get too high, the algae living in corals can no longer function.

Ocean temperatures have been on the rise because of global climate change. The combined effects have caused the longest-lasting coral-bleaching event on record. The bleaching started in The algae living in corals can no longer work when temperatures get too high.See All.

Resistance to Coral Bleaching.I love this SUV but I'm sorry that I didn't get the Hybrid because the gas mileage is NOT good (very disappointed). The ride and comfort is excellent and the visability is great. The blind spot alert could have been better, it lights up yellow rather than bright Red and doesn't beep when a car is in the blind spot and you have the blinker on.

All in all it's a great SUV except for the gas mileage. Report Abuse Read All Reviews 2017 RAV4 Light Years Ahead of Older Model We compared both the new 2017 Mazda CX-5 and the RAV4 and while both are excellent compact SUVs, my wife preferred the lower dashboard and simpler console of the RAV4, so that's how we went. The new XLE version is so much quieter than our older 2011 RAV4 and has a much improved ride. On the mechanical side, the RAV has real good pickup and has kept us in the 30-31 mpg range on our two highway trips thus far.

For an AWD vehicle that's not too shabby. Overall we are extremely pleased with our purchase. Given Toyota's legendary reliability, we expect to enjoy the RAV4 for quite some time.

Lastly, the only improvements I would recommend for the XLE level would be: an additional USB port either in the console or in the rear of the console, the option for heated seats, and a wider choice of cloth seat and dash colors.

First thing I did was reduce the tire pressure to the vehicles door jam specification. Here is my take. Its not as quiet as my 2004 4Runner, especially on rough roads.

On the Freeway it is quiet, so long as the road surface is good. Seats are comfy but the hip bolstering can make it difficult to get out of the vehicle. Stereo sounded pretty good at a stop or stop light, but the sound quality goes down hill as the speed increases. Its nimble and the short wheel base takes all of the credit. The MPG was around 24 with lots of city driving, I'm not a lead foot or a grandpa driver.

So would I consider this for purchase. No, the deal breaker is the amount of noise that makes into the car.

RELATED: Eleven Returns, But Will Is the Key in Stranger Things Season 2 TrailerThe first season centered on the disappearance of 12-year-old Will Byers (Noah Schnapp), who was whisked away to the chaotic Upside-Down dimension by one of its monstrous denizens.

The two groups eventually came together to liberate Will from the Upside-Down, seemingly losing Eleven in the process. Promotional materials for the second season have teased a massive, sinister force on the horizon, with Will seemingly the focus of its attention. Meanwhile, Eleven is back, but what do a series of since-removed episode titles reveal about her arc. And is the nefarious Department of Energy still up to its old tricks.

Most importantly, what about Barb. Well, once those original titles debuted the Duffer brothers discovered they were a little too revealing, as fans began to theorize, piecing together major plot points from little more than a handful of words. After Avengers 4, What Are The Next 20 Marvel Movies.
