Ecosystems, Energy, And Nutrient Cycles
Energy is the capacity to perform work, and it can only be measured in relation to how it affects matter. All organisms require energy to stay alive. All organisms also transform energy. Energy cannot be created or lost, it can only be transferred and transformed. Therefore, in order to perform any kind of function (or work) the body needs energy (the capacity to perform work), and since the body cannot create new energy, it must get energy from outside sources. All energy that is exerted within an organism is transformed into a new kind of energy, and all organisms are energy transformers. All chemical reactions in cells require energy.
Within an ecosystem, energy transfers from one organism to another. This begins with producers, then energy transfers to consumers, and then to more consumers. Producers make their own food by utilizing outside energy, such as plants use photosynthesis to create food using the energy in sunlight. Consumers, however, must obtain energy from either producers or other consumers in the form of eating them. There are three kinds of consumers: herbivores, carnivores, and omnivores. The herbivore only eats producers...
ecosystem" is used frequently in the popular media, and yet most people do not have a clear, working definition of an ecosystem. An ecosystem simply refers to all of the organisms and their physical environment that exist within a certain, specific area. This includes all plants, animals, and their environment, which can include water, dirt, rocks, and the air that surrounds them. For example, all of the organisms that
Tundra Energy Flow Chart Arctic Willow Bacteria Lemming Arctic Wolves Snowy Owl The base of the tundra ecosystem's energy flow is the Arctic willow, a small aquatic plant which grows because of a bacterial process in which nutrients from its body are returned to the surrounding soil. Because animals are unable to derive solar energy directly from sunlight in the tundra, they are forced to depend entirely on plants, which absorb solar energy and utilize it
aquatic system • Describe climate affects selected ecosystem. • Explain, based laws thermodynamics, energy flows selected ecosystem. • Examine matter transported selected ecosystem due biogeochemical cycles, carbon, hydrologic, nitrogen, phosphorus. Aquatic ecosystems Aquatic ecosystems are mainly responsible for assisting energy transfers across the planet and for making it possible for all life on earth to exist. Depending on the area where it is located and on the substances that it contains,
Despite the significance or importance of the microbes, they remain unseen in the context of daily activities or human experiences. They grow and live almost everywhere through application of wide range of resources in comparison to the plants and animals with reference to the lifestyles. Two factors are essential in the growth, development, and operation of the microbes in the marine environment. One of the essential factor is the
Biology Summary A population of grasshoppers in the Kansas prairie has two color phenotypes, green and brown. Typically, the prairie receives adequate water to maintain healthy, green grass. Assume a population of birds that eats grasshoppers moves into the prairie. How will that affect natural selection of the grasshoppers? How might this change in a drought year? In this instance the grasshoppers which are most suitably adapted to current conditions will be
Vertical Farming-Opportunities and Challenges for Singapore There has been much talk surrounding the environmental issues of food production, with many now suggesting the city is the ideal place for growing food to cater for rapidly expanding urban populations. In Singapore, small-scale examples of this are emerging, such as Changi General Hospital and the Tanjong Pagar apartment complex. This dissertation will examine the Vertical Farming movement, and look at the opportunities and
