which abiotic factor on a rocky shore can remove organisms, affect their distribution, and is used to classify a shore as exposed orsheltered?
wave action
light
water loss
temperature

Explanation:

First Question (Seaweed in Lower Shore Zone)

In rocky shore tidal zones, lower shore is more submerged. Red seaweeds (Rhodophyta) are adapted to deeper, lower - light (but still with some light) and more stable aquatic conditions found in the lower shore. Blue - green algae are more in upper zones, brown seaweeds in middle - lower but red is more typical for lower, green seaweeds in upper.

Wave action is an abiotic factor. It can dislodge organisms, influence their distribution. Shores with high wave action are 'exposed', low are'sheltered'. Light, water loss, and temperature don't classify shores as exposed/sheltered in this way.

Answer:

A. Red seaweeds
