, Which statement is NOT true about energy and trophic levels within
a food web?
Most of the energy between trophic levels is lost in the form of metabolic
heat.
Secondary production introduces only 1% of new energy to the food chain.
The rate at which energy accumulates in plants depends on temperature,
sun and water.
About 90% of the energy available at one trophic level does not transfer to
the next.

Which of the following is NOT an example of overexploitation?
Little more than one thousand bison existed in North America by the 1880s.
Fur processing in Canada is carefully regulated to protect both the animals
and the environment.
90 species of Asian turtles are collected in Singapore and Cambodia for
Chinese restaurants.
Slow-growing medicinal plants are harvested before they have a chance to
reproduce.
