Answer:

<em>The correct option is C) The success of a species depends on the number of offspring that survive long enough to reproduce.</em>

Explanation:

Some species of animals such as the octopus might give rise to many offspring, but these offspring might not survive due to different reasons. Only a few of them will be able to survive until the age where they can reproduce.

On the other hand, the survival rate of offspring which are formed in lesser numbers is more. These offspring are taken care of by their parents usually or are better adapted to live in the environment. Hence, their survival rate is more.

Natalka [10]

Answer:

Hilda and her family are going on a sailing trip this summer, and Hilda is especially interested in spotting dolphins. In which zone of the ocean is Hilda most likely to spot dolphins? Hilda and her family are most likely to spot dolphins in the PELAGIC zone. To view shorebirds and crabs, Hilda should move towards the INTERTIDAL zone.

Explanation:

The Pelagic Zone

It is any water in an ocean or lake that can not be said to be positioned in proximity to the shore or in proximity to the bottom (the shore and the bottom are two distinct zones with a completely different properties.

Divisions of the Pelagic Zone

It can be grouped into subzones based on depth, we have the epipelagic, close to the top of the zone which as light been present, and the abyssopelagic, is nearer to the bottom with light being absent.

The intertidal zone

Its found between the high tide (upper limit) and low tide lines (lower limit), majorly on the beach at the water's edge.

The major attribute of the intertidal zone is that it is immersed with water at high tide and is in exposure to the air at lower limit. The intertidal zone is usually undergoing alterations leading to organisms that are uniquely adapted to strive there.

Organisms found in this zone are sea stars, crabs, mussels, barnacles, and various corals as they well situated to strive immersed in water and a region of their lives open air at lower limit.
