When a whale carcass sinks to the ocean floor it creates an environment appropriate for succession to happen. how would you explain this phenomenon?

An ecological succession involves the series of changes in the biotic community with respect to changes in the non-living factors such as water, availability of sunlight and other factors along with time, until the ecosystem attains stability.

When a whale carcass sinks to the ocean floor it creates an environment appropriate for succession to happen because an oceanic floor exhibiting low biological activity before the carcass sinks at the oceanic floor, attains the high biological activity after the carcass sinks. The range of decomposers and scavengers organisms can feed on this carcass. This will result in increase in population of these feeding organisms. Hence, the whale carcass has initiated the succession in the previously less active ocean floor.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
