Question

Scientific research shows that our global climate is changing. The global sea level is rising and ocean temperatures are increasing. Which of the following best predicts an outcome of this global climate change in a coastal ecosystem?
A. The change in temperature will cause organisms that are sensitive to cold to migrate to the area.
B. The milder temperature will encourage a growth in the diversity of sea life.
C. The loss of habitat will lead to endangering or extinction of species living there.
D. The rising sea level will provide water during the drought to species living there.

Answer 1

A is the solution the change in temperature would widen the range specific species live in if  cold temperature sensitive. it would also shrink the area heat sensitive animals have to live in.

Answer 2

The correct option is C.
Organisms living int he oceans are sensitive to water level and temperature change and small changes in the ocean ecosystem usually have big impacts on the organisms that are living in the ocean.
If the water level of the ocean rise and its temperature increases, that means that, some organisms which have been living in the ocean before will no longer be able to cope because of these changed conditions. These species will probably die out  and become extinct.
