Effects of climate change on Great Barrier Reek Rising sea temperature Rising sea temperatures have adverse effects on the Great Barrier Reef (Johnson and Marshal 2007). According to Johanna and Marshal (2007)‚ increased temperature has a significant role in destroying aquatic life because sea animals have a particular body heat limit to survive in the ocean. As a result of enhanced heat‚ this limit has extended beyond that limit (Laugh and Hobdy 2011). For example‚ 8 years ago summer weather was

Dissolved Oxygen (DO) 1. What is dissolved oxygen? Dissolved oxygen is the amount of oxygen mixed into the water and is necessary for aquatic life. 2. How does it get into the water? DO gets into the water in many different way but primarily it is absorbed from the atmosphere and aquatic plants. 3. Why is it important? DO is important because it provides oxygen to aquatic organisms and without it they wouldn’t be able to live. Low levels would cause hypoxia and make it extremely difficult for

These components affect living organisms in many ways. Some of the soluble components and emulsions are poisonous‚ particularly to small organisms that do not have protective coverings or shells- Fish larvae‚ single celled algae and many kinds of plankton are vulnerable and these are the basic foundation of the marine food chain. In shallow water these toxic substances may directly kill algae‚ coral and sea grasses. These components may also be passed in the food chain or directly ingested or absorbed

In this article‚ the author asserts that spreading the zebra mussel in North America is a threat since this invasion cannot be stopped‚ and provides three reasons of support. However‚ the professor explains that there are some ways to stop the spreading of this fish because our knowledge is increased and it is not limited. He also contrasts with the author’s reasons by proving the additional convincing information. First‚ the author points out that the invasion of the zebra mussles might be unstoppable

opposite‚ so areas of high pressures form over the continents. Surface water is warmer and less saline than deep waters‚ meaning that the 2 layers do not mix. Prevailing winds usually go parallel to a coastline Photic zone: light penetrates and plankton grows. High elevations have colder climates: air pressure decreases Coastal areas have a maritime climate: little ligt and seasonal variation Albedo: land of surface to reflect solar radiation; is influenced by vegetation type‚ soils and topography

Requirements The seahorse is an omnivorous animal and the seahorse therefore eats a mixture of plant and animal matter which the seahorse does by sucking the food into it’s body through it’s elongated snout. The seahorse primarily feeds on brine shrimp‚ plankton‚ tiny species of fish‚ and algae.

Small fish eat tiny bits of plastic as if they were normal plankton. Those fish are then consumed by larger species and the plastic contamination moves up the food chain.

that forms in the oceans ultimately results in the conversion of two carbonate ions into bicarbonate ions. This net decrease in the amount of carbonate ions available makes it more difficult for marine calcifying organisms‚ such as coral and some plankton‚ to form biogenic calcium carbonate‚ and such structures become vulnerable to dissolution. Ongoing acidification of the oceans threatens food chains connected with the oceans. While ongoing ocean acidification is a current problem‚ it has occurred
