Farmers want their plants to photosynthesise as much as possible in order to increase their crop rate.
Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis.
Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide.
If it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesise if it gets too hot.
Farmers can use their knowledge of these limiting factors to increase crop growth in greenhouses. They may use artificial light so that photosynthesis can continue beyond daylight hours, or in a higher-than-normal light intensity. The use of paraffin lamps inside a greenhouse increases the rate of photosynthesis because the burning paraffin produces carbon dioxide, and heat too.
An organism that can make its own food is called an "Auto-troph". They maybe of two types:
1) Photo-Autotroph (Get source by sunlight)
2) Chemo-Autotroph (Get source by chemicals i.e., CH₄, NH₃ etc.)
Hope this helps!
Lichens are typically the first organisms to colonize bare rock. They are therefore the pioneer species in primary succession. Many organisms require soil before they can colonize an area. Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process.
The correct answer is: damage to the left posterior brain or left optic radiation.
This condition characterized by the loss of half of the visual field on the same side (right side in this case) in both eyes is called homonymous hemianopsia. This happens because information from the optic nerves crosses to the other half of the brain via the optic chiasm (X shape).Since, the visual images from the right side travel from both eyes to the left side of the brain, it is most likely that the injury, tumor or trauma occurred on the left side of the brain. Stroke can also be the cause for the hemianopsia.
