When a geologist working in stratified rocks observes a limestone bed with oyster fossils overlain by beds with clam and echinoderm fossils indicative of marine conditions, the fossils probably indicate ----- that the environment had changed as the sea level rose and it displaced the oysters environment with marine conditions represented by the clams and echinoderms.
Sea otters hide from predators in kelp forests while underwater.

Do you have a question here?

Algae process photosynthesis thru chloroplast which is a kind of plastid- a round oval disk-shaped body, that is involved in the synthesis and storage of food stuffs.
Chloroplasts are distinguished from other types of plastids by their green color which results from the presence of two pigments namely chlorophyll A and chlorophyll B.
A function of these pigments is to absorb light energy in plants for powering the process of photosynthesis.
