Intensification of agricultural practices causes the loss of biodiversity, and thus influence important ecosystem services. It affects plant production, plant protection, pollination, decomposition processes, nutrient cycles, and the resistance to invasive organisms [15, 63–65].
How does agriculture affect the ecosystem?
Agriculture can contribute to ecosystem services, but can also be a source of disservices, including loss of biodiversity, agrochemical contamination and sedimentation of waterways, pesticide poisoning of non-target organisms, and emissions of greenhouse gases and pollutants (Dale & Polasky 2007; Zhang et al. 2007).
Can biodiversity affect the ecosystem?
Loss of biodiversity appears to affect ecosystems as much as climate change, pollution and other major forms of environmental stress, according to results of a new study by an international research team. … Studies over the last two decades demonstrated that more biologically diverse ecosystems are more productive.
What is agroecosystem?
Agroecosystems, are defined as communities of plants and animals interacting with their physical and chemical environments that have been modified by people to produce food, fibre, fuel and other products for human consumption and processing (Maes, 2018).
What do you think is the role of man in an ecosystem and agroecosystem?
The human processes of farming, industrial production and consumption (or use) of commodities are carried out by similar rules as those of the matter and energy flows of the natural ecosystems. … Waste and scrap are generated and disposed of in the environment during the production and consumption of commodities.
What is the importance of Agroecosystem?
Agricultural biodiversity ensures, for example, pollination of crops, biological crop protection, maintenance of proper structure and fertility of soils, protection of soils against erosion, nutrient cycling, and control of water flow and distribution.
How does agriculture relate to the ecosystem?
Agricultural ecosystems provide a range of services including food production, carbon sequestration, nutrient recycling, and climate regulation (Andrén and Kätterer, 2019). Agricultural crop, livestock, and fisheries production are dependent on the climate.
Why does biodiversity of an ecosystem affect its resilience?
Biologically diverse communities are also more likely to contain species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment.
What is the effect of biodiversity on ecosystem productivity?
What is the effect of biodiversity on ecosystem productivity? Increased biodiversity increases productivity.
How is biodiversity important for ecosystem functioning?
An ecosystem with high species diversity is much more stable than an ecosystem with low species diversity. Also, high biodiversity makes the ecosystem more stable in productivity and more resistant towards disturbances such as alien species invasions and floods.
What is the difference between agroecosystem and natural ecosystem?
So the difference is an ecosystem is natural and an agroecosystem is manmade. An example of the difference between an ecosystem and an Agroecosystem is a farmer plants only one type of seed in a field but in nature, many different types of plants grow alongside one another.
What is an example of an agroecosystem?
Examples of relatively diverse traditional agroecosystems include shifting cultivation, traditional rainfed rice systems, home gardens, and traditional shade coffee and cacao systems. One common traditional agricultural system is shifting cultivation (also known as swidden or slash-and-burn agriculture).
What are the components of agroecosystem?
Abi- otic components of agro-ecosystems include temperature, soil, water, relative humidity, light, and wind. Biotic factors include parasitic and herbivorous pests, competition between crops and other plants, and favorable (symbiotic) relationships among organisms, such as belowground organisms and polli- nators.
Why are pest outbreaks common in an agroecosystem but rare in a natural ecosystem?
Agroecosystems can be more susceptible to pest damage and catastrophic outbreaks owing to lack of diversity in species of plants and insects and sudden alternations imposed by weather and man. However, an agroecosystem is a complex of food chains and food webs that interact together to produce a stable unit.
Which of the following is not a problem associated with agroecosystem?
Answer: The correct answer of this question is option 4,increased dependence on few varieties of plants for food.
