An important part of modern agriculture is maintaining an artificial environment in which plants and animals can grow. a farmer is growing various food plants, such as vegetables and grains.
Explain three ways that he can control abiotic factors and one way that he can control biotic factors. For each method, list the factors controlled and briefly describe their effects on the plants. |
Abiotic factor of water can be affected directly by irrigation and drainage and indirectly by time of planting with different amounts of rainfall during different seasons. Affects all plant activities and is essential for life.
Abiotic factor of soil can be controlled by growing plants in purchased topsoil and by fertilization. Effects vary, since different plants have different optimum soil conditions; provides minerals and other nutrients and affects soil water and oxygen. Abiotic factors of temperature can be affected strongly by radiation, so can be controlled by anything that affects that; can also be affected by growing plants indoors or (indirectly) by planting at different times of year. Affects all plant activities The biotic factors of the use of insecticides to control pestilent insects, allowing plants to grow unhindered. |
