The following abiotic features, shown below, are what determine which organisms can survive in the different zones of the ocean.

• pressure
• light
• temperature
• oxygen
• mineral nutrients

Which of the following most accurately describes an organism that is able to survive in the ocean?

Group of answer choices

An abundance of photosynthetic plankton support the large amount of organisms that reside in the photic zone.

Large organisms, such as blue whales, are able to survive in the mid-ocean depths by adapting to the decreasing pressure at these depths.

At the greatest depths of the Benthic zone, organisms have adapted to the lack of light by evolving very large eyes.

Fast swimming fish are able to survive at the bottom, because they can avoid being eaten by predators.

Being able to adapt to an environment is important if a population of organisms is to survive. Which of the following most accurately describes the adaptation needed to live in a lake?
Group of answer choices

Organisms that live at the bottom of the lake must be able to survive colder temperatures and a decrease in oxygen availability.

Photosynthetic organisms survive using available light at the middle and deep depths of the lake.

At the surface, organisms must have adaptations that help them survive under great pressure and warmer waters.

To live at the middle depths of a lake, fish must have adaptations that allow them to survive in areas with an abundance of nutrients.
