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.
Oviraptor means "egg theif"
Oviraptors could have 20 eggs at a time
They lived in Mongolia
The aren't necessarily true raptors
Oviraptors were about 6 - 8 feet tall
The first oviraptor was found in 1924 (i believe)
Oviraptors lived in the Cretaceous period.
Oviraptors most likely weighed 60 - 70 pounds.
They were renamed, as "ovinutrix"
The first fossil of oviraptors was found with eggs.
