Okay, so this question is about identifying organisms that are playing the role of secondary consumers somewhere in these food chains.
00:08
So let's make sure we know what this is.
00:11
So a secondary consumer is going to eat another organism, but that organism that was eaten itself ate an organism.
00:31
All right, so it should be basically two steps removed from the producers.
00:35
So the producers in this diagram are the photosynthetic phytoplankton that they get eaten by some organism, and then whatever organism eats that organism is a secondary consumer.
00:48
So basically, any organism that is in some way only two steps from the bottom of this food pyramid.
00:55
So let's take a look at the options you have here.
00:57
So the first option you have is a squid.
01:00
So the squid is actually a tertiary consumer in some places, but you see that the squid can eat the fish larva and the fish larva eat the phytoplankton.
01:11
So in that way, on that chain, it is a secondary consumer.
01:15
The anchovy, similarly, in some cases, is a primary consumer because it eats the phytoplankton.
01:25
But in other places, for example, it eats the zooplankton and then those are having eaten the phytoplankton.
01:30
That is a secondary consumer...
