Question

1. Would you expect early successional species to be r-selected or K-selected?

2. Why?

3. ?What about species that dominate later in succession? Would you expect them to be r-selected or K-selected?
You cannot see the individual modules in these photos. You may encounter some unitary organisms. Tube-dwelling worms collect particles on a retractable crown of tentacles. The mouth is in the center of the tentacle crown. The animal on the left has a flexible tube (sec arrow on left) whereas the one on the right has a hard tube (see arrow on right) made of calcium. Barnacles collect food by combing a feathery structure through the water above their

Answer 1

1. I except that the early successional species to be r-related

2. r-selected species produce numerous small offspring followed by exponential population growth. They require short gestation periods, mature quickly, and possess short life spans.

3. The dominating species would be k-related
