1. in the fast change, how are other parts of the ecosystem affected?

2. in decomposition, how are other parts of the ecosystem affected?

3. under which type of change would more organisms be able to survive? why?

4. what are some positive effects of a rapid change to an ecosystem?

5. what are some positive effects of a slow change to an ecosystem?

A change in an ecosystem necessarily affects the species which are part of it, and changes in species in turn affect ecosystem processes. ... This is caused by the extinction of species or loss of populations that had been unique to particular regions and by the invasion or introduction of species into new areas.

Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
