From the data, the manatee population obviously increased after the regulations went into affect and the deaths due to watercraft reduced from 25 to 8 after the regulations were put into effect. The population increased by 165% from 1980=-2010 and the drop in deaths due to watercraft decreased by
68%.So this is not a direct correlation but at least it shows that the watercraft deaths decreased significantly. Since the population increased at a greater rate then it may be that more females were spared so could mate and give birth to that many more manatees.

Answer:
Green plants act as producers because they can generate their own food(glucose) by photosynthesis in presence of sunlight.
Explanation:
Green plants or producers are placed in the first tropic level of energy pyramid.Animals those intake green plants for energy source are called primary consumers such as grasshopper.
Animals those fed on primary consumers for nutrient source are called secondary consumers or primary carnivores for example frog that eat grasshopper for their energy source.
Animals that fed on secondary consumers for energy source are called tertiary consumers or secondary carnivores.For example snake that eats frog to gain nutrients from the later.
The statement above is TRUE.
In evolution, there are different level of succession. Ecosystems usually start out as barren lands or barren rocks; over the course of time, different types of plants and animals will exist on the land and eventual died out and this will continue until the ecosystem has attained its full succession.<span />
