It take over 600 years for primary forest succession to reach the climax, or old-growth, forest. i.e,option D

Succession on land that did not previously have plants, such as soil exposed as a glacier retreats or a new sand bar in a river is called primary succession.

It takes over 600 years to primary forest succession to reach the climax. it includes breakdown of the rocks into soil and plants help in survival of different animal and progress from primary succession to the climax community.

Hence, option 'D' is correct.

Answer: A. Conservation

As temperatures increase, corals lose their symbiotic algae, which provide most of their energy. This is the best description to the effect of coral bleaching on corals. Thus, the correct option is C.

A coral reef is an underwater ecosystem which is characterized by the reef-building corals. Bleached corals are found in the underwater ecosystem which most likely show reduced growth rates, decreased reproductive capacity, increased susceptibility to diseases, and elevated mortality rates than the normal coral reefs. Changes in the coral community composition can occur when the more susceptible species are killed by bleaching events in the ecosystem.

When the conditions such as the temperature change, corals are expelled out the symbiotic algae which is living in their tissues, it is responsible for their colour. A spike of the temperature to 1 to 2°C in the oceans sustained over several weeks which can lead to bleaching, that turns corals white. If the corals are bleached for prolonged periods of time, they eventually die.

Therefore, the correct option is C.
