The first reason we chose to work on aquatic biome is because one its the biggest out of all of them because it covers up most of the world. The second reason is because a lot of people like fishes and the pretty sites that happen underwater. Water is the common link among all of the biomes. The aquatic biome can be broken down into two basic regions freshwater and marine. In the aquatic biome there are many things to discover like the aquatic animals and coral reefs. Freshwater is defined as having a low salt concentration. The animals that live in the freshwater region are used to the low salt concentration. If there was too much concentration in the freshwater region then, the animal that lives down there will most likely die. There are many freshwater regions like ponds, lakes, rivers, streams, and wetlands. The second region that we are going to discuss is the Marine region. The Marine region consists of the ocean and estuaries. An estuary is where the tide meets the stream. Marine regions cover three-fourths of Earth’s surface it includes oceans, coral reefs, and estuaries. T...
Australia is a land of rather extreme weather conditions and widely diverse climates that force the vegetation living there to adapt in many interesting ways. Australia is the driest continent, and biomes such as grasslands and savannas are prime sources of widespread catastrophic fires. The plants that grow in the vast arid and semi-arid regions of Australia are prone to fires simply because of the desert climates that they grow in. High temperatures combined with low fuel moisture contents, little humidity and drying winds that sweep across the landscape encourage many of the plants living in these areas to burst into flames at fairly frequent intervals. Serotinous cones, protective bark, intricate underground recovery systems, unique seed distributions and even the necessity of fire for reproduction are just some of the amazing ways that the major plant families which grow in these fire-prone areas have learned to adapt to their environments.
What is a biome? Biomes are major life zones characterized by vegetation type or by the physical environment. Climate plays a role in determining the nature and location of Earth’s biomes. Texas has 10 different ecosystems with lots of diversity. Minnesota has 4 different ecosystems which are also quite diverse. Regardless of the size of the biomes or the number of biomes in each state, they are all important not just to the locate environment but on a global level because of the life they support. We are going to take a look at the different biomes, comparing climate and rainfall, as well as vegetation fauna.
Fish habitat is the underwater world which many people do not see. It is just like the world that people live. Fish and plants reproduce, eat, and live in this environment, and even face challenges such as invasive species. It is said that “Invasive species are non-native species that threaten the diversity or abundance of native species due to their uncontrollable population growth, causing ecological or economic impacts” (“Invasive” par. 1). Vegetation plays a big role for fish habitat and for a lake itself. Aquatic habitat provides living space for not only fish but also for many aquatic insects. These insects then in turn provide fish and other species of animals with food (“Native” par. 4).
The scientists had originally hypothesized that coastal marshlands had similar water chemistry to that of open water areas whereas beaver-impounded wetlands did not because of the lack of free-flowing water. However, after the Kruskal-Wallis test, they concluded that all water chemistry of open-water, beaver-impounded wetlands and coastal marshes differed quite
Seffen and Moravichik introduce estuaries by explaining the way the freshwater from rivers flow to the sea and mix with the saltwater. Estuaries are Nature’s water blender because in coastal regions the freshwater from rivers meets the salt water of the ocean and are mixed in several different ways. The diverse mixture of salt water to fresh water creates different habitats with a complex ecosystem. Estuaries are important to the environment as well as the economy. Estuaries have very different temperatures and precipitation averages because of the different regions where they can be found. Keeping estuaries healthy is an important job throughout the world. Estuary biomes are full of surprises (Seffen & Moravichik, 2008).
This paper introduces the environmental concerns of the loss of coastal wetlands. The paper will discuss the significance of wetlands and the devastation that is occurring because of human activity. Wetlands are an essential element of our environment both ecological and societal; conservation will be essential for the preservation of these precious ecosystems.
An estuary is a stretch of water that is created out of fresh water from rivers and it mixes with salt water which comes from the ocean. In an estuary the fresh water is blocked from going into the ocean by mainland and salt marshes. But the mixes of salt and fresh waters make an amazing environment that has all different types of animals and plants of all kind.
These areas are incredibly important to humans because of the wildlife. Many species of fish and other animals that are largely used in commercial fishing use estuaries as grounds to breed. Estuaries also remove toxins from the water, making them all the more important. However, as with the Amazon Rainforest, human activity is putting these important habitats at risk of destruction. Estuaries have been overexploited and polluted by humans, decreasing biodiversity and causing them to degrade. The effects are so bad, that humans have suffered from this as well. Several fisheries have been shut down, damaging the economy. Natural disasters have also impacted estuaries, Hurricane Katrina and the tsunami that from Asia in 2004 caused the loss of many mangrove trees, that are vital to wetland

Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturia, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. Tundra is separated into two types: arctic tundra and alpine tundra.
“The sandy beach is a harsh, constantly changing environment,” explained by the UKMCS (2). This is the ocean is constantly moving because of the wind in the earth’s atmosphere (Crawford 4). Along the edge of most coastlines, a commonly found zone is an estuary (Marine Conservation Society (UK) SouthEast 1). This is where brackish waters, an area where freshwater is released and mixed with the ocean’s salt water, is created (1). However, even though there are small amounts of freshwater added, this does not change that the salinity of the ocean is remarkably high.
Biodiversity is described by Ruth Patrick as, “the presence of a large number of species of animals and plants…”(Patrick 15). In other words, biodiversity is the term for the measure of the variety of different species that do exist still on our plant. These species can range from the simplest bacteria to the very complex primates. Biodiversity can relate locally or globally. For example the Southern New England forest contains 20 or 30 tree species while in the rainforest of Peru there are hundreds of species of trees (Patrick 15). There are also further ways to view biodiversity and that is in levels. These levels can be the “diversity of higher plants, number of species, or expressed as sheer weight (biomass)” (Patrick 15). Biodiversity is different is each part of the world. Not every part of the world contains the same amount of creatures yet there are parts of the world that might contain similar amounts. These regions of the world have similar weather patterns and therefore similar species will develop there but they are not necessarily the same. One of the more important regions of the world that contain a large amount of biodiversity is the tropical rainforest region. “The forests comprise roughly 7% of the dry land surface of Earth and may hold more than 50% of all species” (Patrick 15). Yet us as humans do not know all of the creatures and organisms that live on this planet at all. We only have discovered, in one way or another, about 1.4 million species yet the number that is estimated is about 10-100 million (Patrick 15).
Earth is the only planet in the Solar System that has liquid water. The ocean contains ninety seven percent of the earth’s water and covers almost three quarters of the planet. There are four different oceans, the Pacific, Atlantic, Indian, and the Arctic. Tides and currents occur in all three of these oceans. Many different kinds of fish and mammals also make their homes in these oceans. All of these oceans are connected to each other in some way. Humans find oceans to be very interesting, beautiful, and exploring.
What is aquatic biology? Aquatic biology is very similar to marine biology in that you study ecology, behavior of plants and animals, and microbes; however, instead of the main focus being saltwater, aquatic biologists study things like rivers, wetlands, ponds, and other freshwater resources (princetonreview.com). Being an aquatic biologist comes with many crazy experiences, some in college, others with diving, and some with preserving the environment.
Biodiversity refers to wide diversity found in the living components of the earth which refers to the numerous varieties of flora and fauna including those of microorganisms too. The interaction of biotic and abiotic components of the ecosystem is very important aspect of life on earth. Biodiversity helps us to understand the variations among species and also how life originated on earth. Its study helps us to understand the inter-relationship between various forms of life and their adaptation to different conditions.
