Front

Which animal niche is filled first in ecological succession? Options: carnivore, scavenger, herbivore, apex predator.

Back

herbivore

Front

Which two processes are most responsible for forming soil at the beginning of ecological succession?

Back

Front

The diagram above shows how one community of organisms replaces another until which of the following is reached? Options: pioneer community, marine biome, ecological pyramid, climax community

Back

climax community

Front

Lava from a volcano cools and becomes new, barren land. If this land is completely barren, then it would contain –

Back

only abiotic factors

Front

The diversity of animals increases alongside plants because larger plant communities provide -

Back

more chemical energy in the food chain

Front
