If algae populations continue to decline, predict how this might impact the Great Barrier Reef food web.

Answer: the food web would crash.

Explanation: the great barrier reef's diversity would decline more and then the food web would crash since algae was the primary source, no ecosystem can live without a primary source to feed off of to gain energy and grow

Great barrier reef food web protects the coastline and is house to thousands of species. Algae is the primary producer on which the entire food web is based. If it continues to decline, ecosystem will crash.

The biggest coral reef in the world is the Great Barrier Reef. It is situated on Australia's northeastern coast. With a length of 1429 miles and more than 9,000 species, the Great Barrier Reef is enormous. One of the most biodiverse places on the globe, it. Over 3,000 different varieties of coral may be found on the Great Barrier Reef, yet despite supporting such a diverse range of life, the reef is threatened by climate change. Coral bleaching, which harms reefs and the creatures that dwell there, is being caused by changing temperatures and rising carbon dioxide levels.


A food web is a visual representation of how energy moves through an ecosystem. Food webs reveal which creatures in an environment devour one another. Trophic levels are divisions that can be made within food webs. Producers always come first in food webs.


Therefore, if algae (Primary producer)  population continues to decline Great Barrier Reef food web will have a crash landing.

There are two continents with an ocean between them. Today, the continents have very different plants and animals on them. However, a geologist found fossils of the same type of organism on both continents. Millions of years ago, when this type of organism was alive, we know it lived in only one place. The geologist is using the fossils as evidence to argue that the two continents used to be touching. How could the continents have gotten so far apart, and how long did it take for this to happen?
