Question

organisms in the ocean have to compete for space. different organisms have different optimal temperature ranges. the graph below shows the temperature ranges of four organisms.
optimal oceanic temperature of four organisms
graph with organisms (octopus, shrimp, jellyfish, sea cucumber) and temperature in °c (5, 10, 15, 20, 25, 30, 35) axis
at which temperature range will there be the most competition among these organisms?
a 25°c to 30°c
b 20°c to 25°c
c 15°c to 20°c
d 5°c to 10°c

Explanation:

Step1: Identify organism ranges

From the graph: Octopus (~15-25°C), Shrimp (~15-30°C), Jellyfish (~10-20°C), Sea Cucumber (~5-15°C).

Step2: Find overlapping range

Check overlap: 15-20°C includes Octopus, Shrimp, Jellyfish (3 organisms) – more than other ranges.

Answer:

C. 15°C to 20°C
