Question

1. what is the impact of the california current on marine life along the western coast of north america?

a. it reduces fish populations
b. it decreases marine biodiversity
c. it raises sea temperatures
d. it supports a rich marine ecosystem

Explanation:

The California Current is a cold, nutrient - rich current. Cold currents bring up nutrients from the deep ocean, which promotes the growth of phytoplankton. Phytoplankton is the base of the marine food web, so it supports a rich marine ecosystem. Option a is wrong because the nutrient - rich environment actually helps fish populations. Option b is wrong as the rich food web increases biodiversity. Option c is wrong because the California Current is a cold current and lowers sea temperatures.

Answer:

d. It supports a rich marine ecosystem
