The cost of running a large greenhouse is partially affected by the levels of light and temperature of plants are provided with plenty of carbon dioxide the grower can get two Crops a year at 20°c and three crops a year at 30°C in their greenhouses. explain why majy growers use 20°c rather than 30°c in their greenhouses in your explanation suggest why many growers are also investigating in insulation systems that can be added and removed electronically

the bald eagle got 50 because everything gets 10% of what they consume and since 50 is ten % of 500 hundred that means the   grasshopper had to have consumed a plant with 5,000 calories of energy

age range would be the answer

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
