Invertebrate

Have you ever wondered how was it like to live in the freshwater biome? I’m going to tell you some interesting things about thies biome. Surprisingly, only one fifth of the of the earth are freshwater biomes, and only 3% of the water on Earth. Freshwater is located on every continent even Antarctica. I selected this biome because I know that we need freshwater, and I wanted to know where we get it from and who effect by taking it. Next, I will talk to you what the environment is like in the…

Brisbane River (refer to the map) and is an example of a riparian zone, which by definition is “the interface between land and a river or creek” (Dictionary.com, 2015). Freshwater creeks such as Bulimba creek are an optimum habitat where fish, invertebrates, plants and birds thrive in it. They provide “feeding, spawning and/or nursery areas for many species of freshwater fish” and support a diversity of plant communities including “trees, rushes, or floating and submerged aquatic plants”…

mouth of the Atlantic salmon in all its developmental stages also allows it to successfully adapt to these two environments. Generally in the fresh water phase (and this encompasses all the stages prior to smolting), young salmon eat insects, invertebrates and plankton, while adult salmons in salt water eat other fish, squid, eels, and shrimp (Quinn, 2005). This makes the structure of the mouth of the salmon develop differently at each stage to parallel their diet. In stages before smolting…

type I, type II, and type III. A type I curve is where individuals live out their full life, with a heavy mortality at the end. A type II is where survivorship curve will be straight, which is a characteristic of adult birds, rodents and many invertebrates. If mortality rates are extremely high in early life, which is the case in insects and fish, it will take the form of a type III curve. It is expected that people with deaths before 1900 will have a lower life…

Topic B: Ocean acidification and coral reefs Introduction • Ocean acidification is a reduction in the pH of the water in the ocean as a result of increased carbon dioxide uptake in the ocean due to humans burning fossil fuels at such a high rate. • Unless drastic changes are made in regards to CO2 emissions, the rate of ocean acidification is projected to significantly increase over the next century. It is currently estimated that without any changes the pH of the oceans will be 7.8 by 2100 (…

lowering of sea level caused a reduction in ecospace on continental shelves, and the cooling caused by the glaciation itself are some of the big factors for the Ordovician mass extinction. This drop in temperature caused more than 60% of marine invertebrates to die along with two-thirds of all brachiopod and bryozoan families. Number 2: The Devonian extinction The extinction happened about 364 million years ago.…

The Endangered Species Act, like many of the conservation acts, was put in place because people noticed something needed to be done. Although this act is very complex and can be confusing, it has been successful. Nonetheless, since many species are still listed or waiting to be assessed people criticize the act’s effectiveness. In 1966, congress passed the Endangered Species Preservation Act. This listed native animals as endangered and gave limited protection. The act was amended in 1969 to…

Biodiversity, what, who cares, should we pay attention to this? The first question that should be answered is what is biodiversity? To put it simply, it is the study of species and all of their respected families. It covers the whole spectrum of animal life all the way down to the plant life and its variety of those species. Without biodiversity, we would all look the same and there would be nothing different. For example, all the different kinds of flowers you like, only one of them would exist…

reaching sexual maturity 30 to 50 years of age and can live up to 100 years of age if they partook in a healthy lifestyle, which includes living on a primarily herbivore diet (seagrasses and algae) as an adult, while juvenile turtles may feed on invertebrates such as insects and crustaceans. Typically, green sea turtles live and grow in shallow waters, most usually around islands and beaches, near reefs and/or bays, and they are attracted to lagoons due to their abundance in nutrients. The only…

snapping movement while lowering the floor of its mouth to intense the volume. The snout is designed to suck up microscopic animals that live in the sea (Dive 1). These creatures include small crustaceans, brine shrimp, zooplankton, worms and other invertebrates (Dive 1). Seahorses usually ambush these…
