Understand ocean ecosystems as interconnected systems where living things (producers, consumers, decomposers) and non-living factors (temperature, salinity, light, currents) all interact, and that changes to one part affect the whole system
A first look
This shelf is still being planted — the questions are being written and checked. Come back soon. A Skill needs at least 5 checked questions before it opens here.
Question 1 of 3
Which statement best describes an ocean ecosystem as a system of living and non‑living parts that interact?
Question 2 of 3
In a coastal kelp forest, which statement best describes how the living and non‑living parts work together as a single ecosystem?
Question 3 of 3
When the water in a coral reef becomes warmer than normal, which chain of effects is most likely to happen? A. The coral loses its color, the fish lose their hiding places, and the number of fish that bigger predators eat goes down. B. The coral grows faster, providing more food for herbivorous fish, which then increase the number of small sharks. C. The water becomes clearer, allowing more sunlight for plankton, which raises the number of sea turtles. D. The temperature rise makes the water less salty, causing all fish to move to deeper water immediately.
