An example of this, according to Raven, Berg and Hassenzahl, is “an organism in an environment” (43). Phytoplankton, Zooplankton and Benthos are all living or biotic organisms this study examined in the starch factory stream. Phytoplankton are, according to Raven, Berg and Hassenzahl, “free-floating photosynthetic algae and cyanobacteria that form the base of most aquatic food webs” (124). Phytoplankton is green when examined in a microscope while zooplankton is not. Zooplankton are defined as “nonphotosynthetic organism that include protozoa (animal-like protists), tiny shrimplike crustaceans, and the larval (immature) stages of many animals.”…
The effect of caffeine on the heart rate of Daphnia pulex Introduction In this experiment the effect of caffeine on the heart rate of Daphnia will be tested by use of a microscope and caffeine solution. Daphnia pulex is a crustaceous animal found in the ocean. There internal organs can be visible to observe because their body is translucent. This would be interesting because we could see how the effect of caffeine effects the heart rate of humans as well.…
"Monster is a relative word; to a canary, a cat is a monster. So far we humans were used to being cats." After the first three movies in the series, you might think that they would have learnt of their incapacity to contain a dinosaur – precisely the reason why Jurassic Park was shut down at the end of the third movie. Twenty-two years later, the park has been reopened, renamed and revamped. The theme park, dubbed Jurassic World, is now owned by Simon Masrani (Irrfan Khan) who has taken Hammond's dream of a dinosaur amusement park to a whole new level.…
Just north of Key Biscayne in sunny Miami, Virgina Key is a protected barrier Island in the Atlantic ocean. Consisting of 863 acres of land, it was once much larger, extending into the Ft. Lauderdale area. Between 1835 and 1838 hurricanes eroded the beach, creating inlets and dividing the island in two. The other portion became Fisher Island, which sits at the southernmost tip of Miami Beach. Virgina Key was a part of the civil rights movement.…
In contrast to most sea creatures, these unique critters “live on the skeletons of whales, which drift down to the ocean floor” (Ennis). Because zombie worms are attached to the whale bones, they must use them to contribute to their diet. These ocean animals “lack a mouth and gut, [so] the worms drill into the bones [to] extract the stored nutrients” (Ennis). Without this adaptation, zombie worms would starve and die. Zombie worms also have an additional way to digest food through their bodies; they “[use] a process called symbiosis, in which the worms depend on the internal bacteria to digest the fats and oils extracted from their whale-bone diet” (Ennis).…
Adaptations include camouflage and poison. Producers like Halophila seagrasses, diatoms, cyanobacteria, mangrove trees, zooxanthellae, sea lettuce, caulerpa, dinoflagellates, coccolithophore, and rhodophyta, whether they are green plants or phytoplankton, all adapt to stay in the reef. Adaptations include roots that anchor the organisms into the mud and protective cell walls. Coral is a keystone species of the GBR. Without them, the reef’s biodiversity would dramatically decrease, organisms would lose their homes, & a source of…

In the movie, Finding Dory, underwater algae and plants appear in nearly every scene. From kelp to seagrasses, these algae and plants serve an important cinematic role as mysterious curtains and beautifully flowing details, but in the real world, these algae and plants serve just an even more significant function. Early in the movie, baby Dory searches the kelp forest by the Marine Life Institute, and later she returns to find her parents in the same kelp forest. Kelp forests are some of the most productive ecosystems on Earth, with dense growth of kelp, very large brown algae. Kelp is thought to have evolved from other brown algae only 23 million years ago.…

We have been able to observe marine organism in the clade Littorinimorpha in the three tides zones high, mid, and low each have their own ecological niche for marine organisms. But there is some marine life that are able to live in patchiness within zones and thrive in more than one. The high intertidal zones are home to marine life that are more tolerant to air, like barnacles (Ricketts et al. 1968). The mid zone includes higher low water and lower low water, which can be indicated by limpets (Ricketts et al. 1968). Last the low zone includes those that are normally uncovered during minus tides (Ricketts et al. 1968).…
Ningaloo Reef Marine Ecosystem 1. Identify ten organisms from your chosen ecosystem and draw a food web to show trophic interactions between them. Within this food web, you must include and label a decomposer. Ten organisms that live in the Ningaloo Reef include the bottlenose dolphin, loggerhead turtle, tiger shark, whale shark, Southern Calamari squid, jellyfish, zooplankton, dugong, phytoplankton and seagrass. The decomposer in this food web is bacteria, which works to further break down the dead organic matter in the bodies of plant and animal organisms.…
Echinoderms are very significant in the environments they inhabit. They demonstrate critical ecological roles in marine habitats, such as controlling algae growth, feeding other species (marine and terrestrial) and acting as hosts for numerous symbiotic organisms. Furthermore, as a keystone species in many marine ecosystems, their numbers can radically alter entire ecosystems. Sea urchin populations play a large role in the functioning of kelp forest ecosystems, with profound effects (positive and negative) on the kelp community structure. They help control kelp population, yet destructive grazing of an uncontrolled urchin population can have a negative damaging effect over time, creating vast areas with no kelp (urchin barrens).…
Increased ocean acidification isn’t the only thing affecting the ocean, but it is very problematic because it erodes aragonite which is a mineral of calcium carbonate. In other words it kills corals and causes the hard exoskeleton to erode. Action needs to be taken to ensure the survival of corals and the creatures that rely on coral reefs to survive. Coral reefs are sources of food for millions of people, but also are sources of medicines. As coral reefs disappear so do the organisms that are mutualistic to it.…
Coral reefs are diverse underwater ecosystems composed of small animals known as coral polyps, the skeletons of dead corals, and the various plants and animals that take refuge in the rich environment they produce. Sadly, the world 's coral reefs are dying. Ocean acidification, rising water temperatures, and disruption in the balance of sea life combine to form a lethal threat to these beautiful natural wonders. But what is really killing coral reefs? We are.…
This means that bioluminescence is the only source of light, which affects the vision of the organisms that live in the deep ocean. Because it is harder, if not impossible, to see in the deep ocean, it is a lot more difficult to find mates, avoid predators, and find food. To survive, many organisms have changed their colour over time to blend in with the darkness to avoid predators, or developed bioluminescence to find prey and for defence. Some organisms may even have developed larger eyes or feelers to increase their sensitivity.…
