Describe the life cycle of a diadromous fish, River Herring. What affect does the fish's life cycle have on the entire food web?
River Herring, a diadromous fish, live part of their life in fresh water and part in salt water. River Herring start off their life in freshwater streams as eggs. Once those eggs hatch, the young fish will stay in the coastal streams for a month or two until ready to return to the ocean. They will live out their lives in the ocean and as adults return to their "birth stream" to spawn. Their life cycle has a tremendous impact on the food web, because River Herring are eaten by many different organisms. They are the base of the food chain, and help support species in ocean, estuarine, and freshwater environments. Everything from whales to tuna, seals to river otters, and coastal birds will eat these fish.

How can you better prioritize your assignments?
The first step could be to make a list of all your assignments that need to be done. Next to each task write when it is due, and how much time you think it will take to complete. You can then prioritize assignments that need to be completed sooner. If there are tasks that have a similar due date, it may be beneficial to complete the shorter task first; helping you feel like you are accomplishing items on your list and giving you fuel to move onto those more complicated tasks.

Many States in the US are looking at offshore wind energy as a renewable energy alternative to fossil fuels. Offshore wind energy has tremendous potential to create affordable, clean energy, a diversity of new jobs, and reduce our dependence on fossil fuels. However, we are not aware of all of the ecological impacts that offshore wind may have. Scientists are currently focusing on research to better understand what impact turbines will have on the surrounding marine ecology and habitat. Describe one potential ecological advantage and disadvantage of offshore wind energy.
One potential ecological advantage of offshore wind turbines are that they can promote reef creation along their base, so mussels and other organisms may start growing around the bottom. These reefs will increase the habitat diversity in the area, attracting more fish and other marine organisms. One potential disadvantage to offshore wind energy, is that the noise from construction could negatively affect marine animals like whales that use sound to navigate through the water and communicate with other animals.
