blue crabs are a vital part of not only the chesapeake bay ecosystem but are also important for
commercial fisheries and tourism. below is data representing hypothetical blue crab populations if
practices for reducing pollution, habitat loss and fishing regulations would have all been put into place.

1. using the grid below, create a graph from these data
2. what type of growth curve is represented by the data?
3. based on the data and graph estimate the blue crab population in 2020?

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
