They play a role in decomposition because after feeding on decomposing plants, they return the organic material to the soil so it can be further digested into nutrients for growing plants. They are also able to remove toxic…
For years this planet has been undergoing vast changes in its environment, wildlife, and mostly our oceans. The acidifying of our oceans is because of all the Carbon Dioxide that is absorbed by seawater. A chemical reaction that occur which reduces seawater's pH. All of the Carbon Dioxide is being put into our atmosphere by the burning of fossil fuels. Calcium carbonate minerals are the building blocks for the skeletons of shells of many marine organisms. In certain areas where life now congregates in the ocean, the seawater, is supersaturated with calcium carbonate mineral.…
1.Summarize the information from the group visual The visual contains the role and impact the inverse specie,Green Crab has on the ecosystem. The Green Crab is native to Europe but at time went by it spread to America,australia and is at risk of spreading all over the world. The spread of Green Crabs was most likely by natural dispersal in the oceanic currents,or by domestic dispersal mechanisms. Also Green Crabs can tolerate a wide range of environmental extremes such as cold temperatures, low salinities, etc ,which means controlling their population is very difficult. The invasion of green crabs has huge impact on the ecosystem as they are carnivore, who eat Oysters,clams and hundreds of other Species.…
Despite the large, dead tree limbs on the trails and forest floor I thought that perhaps if these limbs weren’t on the forest floor decomposing and adding nutrients back to the soil; then there may not be as much tree diversity. Although many people feel it is our job to manage and manipulate nature to be ‘healthy’, we as humans cannot mimic mother nature and sometimes it is important to recognize that although a forest may not appear healthy in our eyes, it could be functioning in a way that is natural. Years before humans altered ecosystems, they functioned on their own and have adapted to many environmental…
Ecologically, oysters are important because they filter algae, sediment, and pollutants. They maintain a good water quality and salinity. Oysters can tolerate a wide range of salinity, between 10ppt-27ppt. Humans have had huge positive and negative impacts on oyster population. Things that destroy an oyster population include over harvesting, habitat destruction, water quality and diseases.…
"Many people rely on wetlands for their livelihood, as they are important centers for hunting, fishing and recreation" explains Elaine Mao in her article Wetlands and Habitat Loss. She also explains that wetlands like the Everglades filters, cleans, and stores water. Not only does it allow hunting, fishing, and recreation, and filtering, cleaning, and storing of water, it gives us protection of floodwater and hurricanes while allowing a ginormous diversity of species to live there.…
With more and more people coming into the world, it is difficult to regulate and mange all of the variables that include population growth. As populations rise, there is an increase in demand for food, resources, and also an increase in waste. While for many years it seemed okay, now researchers are finding that there are many cases where human waste is going to the wrong places causing disease, and many ecosystems to falter. This is happened across the globe, from China, to Brazil, and up to Washington D.C. in America. Directing our attention to Washington D.C., we can see how humans have disrupted the ecosystem and are now in jeopardy of not being able to restore it to it’s previous greatness.…
Louisiana Wetland Loss The loss of Louisiana's seaside wetlands is a standout amongst the most genuine natural issues confronting the nation today. Louisiana brags more than 4 million sections of land of wetlands, speaking to 40% of the country's aggregate. These wetlands are among the world's most different and gainful biological communities. In the blink of an eye, Louisiana's wetlands are in a condition of fast debasement.…
Learning Journal Unit Eight How did you like the course overall? Overall, despite the difficult nature of the course, I enjoyed taking the introduction to biology course. Moreover, the material covered in the class enriched my knowledge regarding the variety of species and organisms that inhabit our world and has inspired me to become a more proactive steward of my environment.…
Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. Biogeochemical cycling is defined as the chemical element flow between the living and nonliving components of the ecosystem. This is the cycle of nitrogen, phosphorus and carbon being converted into organic substances of plants and animals that are released back into the environment. There are three ways that human activities cause an imbalance of biogeochemical cycling on a daily basis.…
he Pine Marten is an amazing animal to know about. This animal can do many amazing things that other animals can’t. So let me tell you these many amazing things that this animals can’t do. The Pine Marten lives in the Deciduous Forest. The climate there is very cold and rains a lot.…
Introduction The agricultural industry is the key industry that feeds, clothes, and keeps the population of the world comfortable in their homes. Members of this large, yet dwindling industry are faced with the challenge of feeding a rapidly growing population that is expected to reach 8.5 billion people by the year 2030. The major component fueling the agricultural industry is the soil. The very outer layer of the earth’s crust is the very one thing keeping the population thriving.…
(Gain attention) President Barack Obama once said “There’s one issue that will define the contours of this century more dramatically than any other, and that is the urgent threat of a changing climate.” (Reveal Topic) This statement by President Obama on climate change conveys how important the fight against climate change is. (Establish Credibility) I became interested in this topic after getting into a disagreement regarding climate change with my grandfather and how he doesn’t “buy into that liberal bullshit,” so I set out on a mission to prove him wrong by conducting research with the goal of fully understanding the climate change debate. (Preview the Body)…
Soil preference of the Red Compost Worms, Eisenia fetida INTRODUCTION Earthworms provide countless benefits to humans, plants and animals, by improving drainage, advancing nutrient accessibility, and providing a steady soil system, helping to develop farm production. They benefit the soil ecosystem by decomposing and recycling organic matter, opening up pores inside the soil to develop its formation and supplying food for predators . By adding nutrients to the soil they inhabit, earthworms are constantly working to keep soil healthy in order for plants to grow well in it .…
Soil is the Earth’s fragile skin that supports all life on Earth. Soil anchors the majority of the world’s biodiversity and soil that is a healthy essential to attaining food production and providing an adequate water supply for a long period of time. Soil degradation is a decline in the soils quality caused by improper use such as agricultural practices and industrial or urban practices. Soil degradation can cause a serious global problem and may be aggravated by climate change. Examples of soil degradation includes loss of organic matter, decline in structural condition, erosion, adverse changes in salinity, acidity or alkalinity, and the effects of toxic chemicals, pollutants or excessive flooding.…
