Certain species of fish are unsafe to consume in high quantities because these fish

a. ingest other fish that are poisonous to humans.
b. have high levels of metals in them from cancer-causing pesticides.
c. are endangered species.
d. contain vitamins that aren't water-soluble and can cause toxicity.

don't guess, try to give the correct answer

A. ingest other fish that are poisonous to humans.

Explanation:

In a food chain a primary consumers eats the producer, a secondary consumer eats the primary consumer and then the tertiary consumer eats the secondary consumer. The level of poison will increase as it goes down the food chain so the tertiary consumer will have the highest amount of toxins in it.

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
