Ecological succession leads to the sustainability of life in an ecosystem. Succession is the observed process of change in the
species structure of an ecosystem. The community begins with relatively few pioneering plants and animals and develops
through stages of increasing complexity until it becomes stable. Succession may be initiated either by formation of new,
unoccupied habitat such as the formation of an island or by some form of disturbance such as fire in an existing ecosystem.
Succession that begins in new habitats, uninfluenced by pre-existing communities is called primary succession, whereas
succession that follows disruption of a pre-existing community is called secondary succession.
If a tornado destroys a deciduous forest, what kind of succession follows?
A)
classic ecosystem
B)
climax community
primary succession
D)
secondary succession

Put the following processes of protein synthesis in the correct order: - dna strands unwind and separate - mrna copies dna according to complimentary base pairing - trna's anticodons bring amino acids to the corresponding mrna codons - amino acids bind to each other making a protein - mrna leaves the nucleus - a stop codon is reached, the newly formed protein is released to go do its job for the cell
