Removal by humans of large predators from coral reef ecosystems has resulted in

Lack of shelter, due to lack of physical structure, in the epipelagic can be solved by:

One disadvantage of manufactured pesticides that are used to prevent insect damage to crop plants is that they often end up harming  freshwater and marine animals when they wash off the land

When algal species that had been used in successful mariculture programs in some parts of the south Pacific were transported to Hawaii (where they do not grow naturally) to build a mariculture program there, they began to grow unchecked on the coral reefs, smothering the corals.

For each of the following marine organisms, please write the letter corresponding to the listed characteristic (A through D below) that contributes most to their vulnerability to extinction.   sardines

Mariculture is most successful (i.e., sustainable and not damaging) if the coastal mangroves are completely cleared away so that they don’t interfere with building roads for the trucks that carry the seafoods to markets

Jackson et al. 2001 recommend focusing on restoring key consumers to marine ecosystems because

For each of these ecosystems, which is the resulting problem that the 2001 paper by Jackson and 18 other authors consider to have been caused by removal of too many consumers?   coral reefs

The roots of the auxiliary equation corresponding to a certain 10th-order homogeneous linear differential equation with constant real coefficients are: -1, -1,-1, 3, 2-i, 2+i, 4+3i, 4+3i, 4-3i, 4-3i Write down the general solution of this equation.
