Mufasa is talking about the ecosystem. All animals in the ecosystem are connected, and therefore each requires all the others for its survival. If the balance is not respected - for example, if humans wipe out one particular species - the entire ecosystem will suffer as a result. 7) In an attempt to explain the Circle of Life, Mufasa says to Simba; “when we die our bodies become the grass……the antelope eat the grass……” How is this possible? Describe the process that Mufasa is referring to in detail.
Plants are the producers for an ecosystem. They photosynthesise carbon dioxide and water and produce energy in the form of carbohydrates and other molecules. Photosynthesis requires water, and plants gain water from the soil using mineral ions such as nitrate produced by the nitrifying bacteria. Hydrolysis of ATP releases energy for processes such as active transport of the nitrate ions (and others such as potassium etc) from the soil into root hair cells, a process that lowers water potential and is used to draw water into the plant from the soil. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.
Abstract Intraspecific and interspecific competition plays a major role in stabilizing environments. These mechanisms ensure that no species can go beyond its environments carrying capacity. The purpose of this lab is to determine the effects of density on biomass of plants and the effects of predators and abiotic factors in an environment. This will be tested with the spinach plant Spinacia vulgaris of varying densities in the same sized pots and with the use of P. aurelia, P. bursaria and P. caudatum divided into control and experimental groups. The results showed that the increasing of the density leads to a decrease in the biomass of plants and that the experimental groups are not much different than the control groups.
The conclusive data shows that the buckthorn shrub was affecting the soil properties by adding higher concentrations of elements in each of the three wooded areas sampled. The buckthorn shrub is like a sponge to the soils minerals sucking every mineral and drop of water it needs to survive and flourish, which leaves the soil highly concentrated, making the competition for soil minerals and water extremely high between native shrubs and the European buckthorn. Since the buckthorn is so physically dominant, many native shrubs cannot adapt to an environment shared
Ecology unit Test 1. Which of the following is true about ecology? (1 point) (a) Ecology is a philosophy that seeks to limit harm to the natural world. (b) Ecology is a practice that emphasizes preservation of life. (c) Ecology is an area of study that focuses on interactions in nature.
Rotten Apples I had an interest in decomposition and how it can help the earth and the world become a better place. The environment has a big issue when it comes to decomposition. The environment is a big issue when it comes to decomposition. I begin to think if the worms in our soil could decompose faster would that possibly help us with space for the wasted land we use for the trash. After a little research what was hypothesized was that the night crawlers would make the apple decay faster because they are a special breed.
The Ecological Footprint measures the sum of these areas, wherever they physically occur on the planet. The Ecological Footprint is used widely as a management and communication tool by governments, businesses, educational institutions, and non-governmental organizations. What does the Ecological Footprint measure? Ecological Footprint accounts answer a specific research question: how much of the biological capacity of the planet is demanded by a given human activity or population? To answer this question, the Ecological Footprint measures the amount of biologically productive land and water area an individual, a city, a country, a region, or all of humanity uses to produce the resources it consumes and to absorb the waste it generates with today’s technology and resource management practices.
Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters. Extinction of theses invertebrates would totally disrupt the balance of the ecosystem. The aim of this study is to bring awareness about the harmful impact global warming has on the local aquatic invertebrates and on the ecosystem at a global scale. The hypothesis for this study is that the biotic diversity of the slow moving water and fast moving water are driven by abiotic factors. To support this hypothesis, three predictions were made.
7. How do your findings relate to relevant theories in environmental science? Specifically: a. Do your results indicate that any of the species are keystone species? Do they support the theory of bottom-up or top-down control of population dynamics in ecosystems?
There are many different reasons why extinction happens, some of these cause are natural but the majority of them are due to human activity such as deforestation and an increased amount of fossil fuels being used which then leads to global warming. Extinction has increased 100,000 times more than before humans were on earth. There currently is a mass extinction of species since the extinction of the dinosaurs 65 million years ago, some of the main causes of this are habitat destruction, invasive animals, population growth, pollution and over exploitation. Biodiversity is the variety of plants and animal life in the world or in a particular habitat which are affected negatively due to some activities that humans are causing such as climate change. My first piece of evidence in favour of human activity leading to extinction is ‘humans are driving animals to extinction faster than they can evolve ‘written by Juliette Jowit, (on Sunday the 7th of March 2010), the guardian newspaper, 15/01/15.
