An orange roughy fish eats squid and small fish. it also is eaten by predators like dolphins and sharks. where would the orange roughy most likely appear on a food web?

a. it is a primary producer because it provides food for the dolphins and sharks.
b. it is a tertiary consumer because most of the things it eats are secondary producers.
c. it is a secondary consumer because it eats two types of things.
d. it is a primary consumer because it has both predators and prey.

The correct answer would be B. It is a tertiary consumer because most of the things it eats are secondary producers.

In a food chain or web, the tertiary consumers are those which can consume primary as well as secondary consumers.  

They are either carnivores, that is, meat eater or omnivores, that is, those who consume both plants as well as animals.

Similarly, orange roughy fish consume organisms like squid which is itself a secondary or tertiary consumer in a food chain. It can also consume small fishes which are primary consumers in a food chain.

Thus, orange roughy fishes would be a tertiary consumer in a food web.

B. It is a tertiary consumer because most of the things it eats are secondary consumers.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
