Introduction
Ecosystem is the scientific study of interaction of living and nonliving things with each other but if any ecosystem is created artificially and is maintained to satisfy human needs is called agriculture ecosystem or agroecosystem.
Natural ecosystems usually contain hundreds or thousands of species of organisms and are very complex in their functioning. But agricultural ecosystems are relatively artificial and are being modified and controlled by humans. The main characteristics of agriculture ecosystems are:
• They contain fewer species and are simpler in their functioning.
• Agricultural ecosystems are made up of largely domesticated animals and plants that are used to produce food for humans.
• In agricultural ecosystems, …show more content…

Energy flow in agricultural ecosystem
Agriculture ecosystem is designed in such a way that maxim of sun energy can be utilized to maximize production of specific crop. It involves two fold processes:
1. Human and animal labor, fuel power machines and many other sources are used to convert sun energy directly into food.
2. Genetic engineering is used to transfer only desirable triads in plants and animals into next generations to maximize the yield of specific products from them.
In a food chain, there are basic steps that carry solar energy to human. Plants use soil nutrients, water and carbon dioxide from the air, and with the sun energy and produce food that is utilized by animals and humans. This can be shown as: Development of agricultural ecosystem
Why is agricultural ecosystem developed?
About 10% of world ice-free land is cropland and is covered with grasslands, forests, deserts and wetlands and 20% is pasture that is designed for animals rather than plant production. So, about 30% of the terrestrial world surface is available for agricultural

    Traditional agriculture requires massive forest and grassland removal to obtain land necessary to farm on. Deforestation and overgrazing has caused erosion flooding, and enabled the expansion of deserts. But with drainage systems, leveling, and irrigation provided by the Green Rev, all this terra deforming will unlikely happen again. We can retain clean air and lessen the global warming effect caused by deforestation.Many people argue that a revamp in agriculture will be way too expensive and unrealistic especially for those poor farmers in third world countries. However many times, they exaggerate the price.

    2078 Words  | 5 Pages

    Agriculture is the major farming activity. Agriculture's scale means not only that large area is directly affected, but that local and even regional climates can be affected. The draining of water from rivers and watersheds for irrigation leads to drier natural habitats. Those rivers that receive runoff from farmland are often poisoned by excessive nutrients and pesticides.

    The growth of the world’s population has led to a growth in animal agriculture, because as population grows, the need for food does as well. Animal agriculture is the use of animal farms to produce animal products that are then consumed by the general public. As agribusiness expands, issues such as the need for farm insurance and animal rights have received more awareness. Modern day industrialism is being applied to animal agriculture in developed nations such as the United States and Canada.

    Genetic engineering is a way in which specific genes for an animal or plant can be extracted, and reproduced to form a new animal or plant. These new organisms will express the required trait for that gene. This practice is a very controversial topic within the scientific world. It is being implemented in various areas such as agriculture, even though there are many alternatives that can be found for genetic engineered crops, such as organic materials and reducing leeching of the soil. The controversy regarding this practice occurs as it is believed to contribute both negative and positive implications and dangers, not only to oneself but the environment as a whole.

    How is the important of food production? That agriculture is one of the most essential means of producing food is realized easily when we think of the types of things that we eat. The rice or wheat that we eat comes from the land. Even potatoes and other roots or vegetables and even leaves such as tea, as well as the fruits that men eat are the products of the soil that covers the earth. In fact, everything that we eat, except meat, fish and other kinds of flesh comes from the land, and what grows on the land is part of agriculture. Even the sugar, oil, coffee and other beverages that we use are products of plants that grow on land. In the same way, many of the medicines that we use is made of plants that grow in various parts of the

    I am certain that all have heard of the terms greenhouse gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008).

  • ENVIRONMENTAL POLLUTION

    1653 Words  | 4 Pages

    The branch of science that deals with how living things, including humans, are related to their surroundings is called ecology . The Earth supports some 5 million species of plants, animals, and microorganisms. These interact and influence their surroundings, forming a vast network of interrelated environmental systems called ecosystems. The arctic tundra is an ecosystem and so is a Brazilian rain forest. The islands of Hawaii are a relatively isolated ecosystem. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Complex ecosystems are able to compensate for changes caused by weather or intrusions from migrating animals and are therefore usually said to be more stable than simple ecosystems. A field of corn has only one dominant species, the corn plant, and is a very simple ecosystem. It is easily destroyed by drought, insects, disease, or overuse. A forest may remain relatively unchanged by weather that would destroy a nearby field of corn, because the forest is characterized by greater diversity of plants and animals. Its complexity gives it stability.

    Crop rotation is the consecutive cultivation of different crops in a fixed order in the same fields. Crop rotation began as early as the nineteenth century. This aspect of farming helps to prevent soil erosion, as well as provide the soil with extra nutrients. This in turn benefits farmers by making more use of their fields, and helps to produce crop year-round.

  • Loss of Biodiversity

    998 Words  | 2 Pages

    One of the reasons for loss in biodiversity is alteration of habitats. A habitat is the natural environment in which a species of living organism lives. If the habitat of a species is changed, it will cause the species to die or migrate to other places where it can find its natural habitat. There are many ways in which the habitat of plants and animals can be altered. One of them is land use changes. Since the beginning of human life, human beings have been changing land use for farming. Large areas of forests have been cleared by humans to increase the area of farming to satisfy their growing needs. Many biodiversity-rich landscape characteristics have been lost due to intensive farming (Young, Richards, Fischer, Halada, Kull, Kuzniar, Tartes, Uzunov & Watt, 2007). For example, traditional farming was replaced by private farms in Europe after the First World War causing an immense change in land use patterns. Another major proble...

    ...o climate change. All of these have caused an impact on the ability to produce crops and grow agriculturally. Climate change has been increasing the number of droughts, floods, health hazards of employees, natural disasters, and sea level elevations. All of these put in danger the crop productivity resulting in famines and food price increments. Climate change affects agriculture in every country differently due to its location. Countries such as Canada and Russia are being affected positively by climate change since it has enabled the country to prosper agriculturally. Other countries cannot handle drastic temperature changes, such as Sudan and Bangladesh, whose agricultural growth has been affected negatively by the climatic changes. Agriculture is fundamental in a country, creating a balance between agriculture and the increasing climatic changes would be ideal.
