If a disturbance were to occur in an ecosystem, which of the following ecosystems would be most vulnerable to extinctions? continental ecosystems island ecosystems marine ecosystems tropical ecosystems

The answer is D: tropical ecosystems

Explanation:

Its is tropical ecosystem because they are the most fragile, and intricate systems

marine ecosystems and tropical ecosystems

Explanation:

For example, Caribbean coral reefs, whose natural barrier is at serious risk of disappearance, such as tourist exploitation, overfishing, etc. The Aral Sea is another example of a collapsed and unrecoverable sea.

Climate change will affect many species and habitats and will have a consequence on fishing. Displacements of marine species due to warming of the waters can cause invasions high rates of local extinction in the tropics and seas. Molluscs, echinoderms and corals that form reefs, are very sensitive to crustaceans and fish, which can have harmful consequences for fishing.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
