Secondary succession is to a forest that has been destroyed by fire as primary succession is to a:

In an ecosystem, elements such as nitrogen and carbon move between living things and the environment. The conversion of these elements are part of:

Biogeochemical cycles

Which order of diagrams below would show primary succession?

C, A, B, D

Tropical Rainforests

Stratified communities with vines, orchids, and monkeys with nutrient poor soil

Hydrothermal vent communities are often destroyed by lava erupting from the ocean floor. After the lava has cooled, different organisms begin to inhabit the area. Over a period of a few year, organisms inhabit the area in the following order: sulfur bacteria-crabs-giant tubeworms-clams & mussels. Which of these BEST identifies this sequence of events?
