Pesticides, though non-biodegradable, are both beneficial and harmful for agriculture. Select the INCORRECT option regarding pesticides.

Key Point

• Pesticides are compounds used to prevent, destroy, and control pests.
• Pesticides, though non-biodegradable, are both beneficial and harmful to agriculture. They alter nitrogen metabolism, so less protein content in plants
• Pesticides  reduce the chlorophyll content  of the plant and hence affect photosynthesis. They reduce plant growth.
• In some cases, the soil, water, turf, and other vegetation could all become contaminated by pesticides and the pesticides can be toxic to some non-target plants and animals.

Additional Information

• The first stage of the nitrogen cycle and a vital biological activity is nitrogen fixation. A number of bacterial species, including Rhizobium, Azotobacter, and others, as well as other natural phenomena, participate in this process, which turns atmospheric nitrogen into ammonia.
• The primary mechanism of nitrogen metabolism is the recycling of ammonia into the neutral or charged form of ammonium ion. The nitrogen cycle is the fundamental process involved in nitrogen metabolism.
• By converting light energy into chemical energy through a process called photosynthesis, plants can subsequently release that chemical energy to power their activities. Solar energy, water, and carbon dioxide are needed for the photosynthetic process, which yields oxygen as a byproduct.
