Ecology - Ecological succession

4 important questions on Ecology - Ecological succession

What 3 things weathers a rock?

Wind, rain and frost. Grit formes in the crevices and cracks in particular. The wind carries small soil particles that get mixed in with the grit. This subsoil is enough for lichen to grow.

What does humus consist out of?

What is a climax community?

The final stage of succesion in which the abiotic factors are more or less consistant. The exsisting plant and animal species are no longer replaced by other species.
it is usually rich in species, this makes the food web more complex.
