Explain how marine ecosystems can have greater biomass of consumers than producers.
Marine ecosystems are among the largest of Earth's aquatic ecosystems, salt marshes, intertidal zones, estuaries, lagoons, mangroves, coral reefs, the deep sea, and the sea floor. They can be contrasted with freshwater ecosystems, which have a lower salt content.
The new biomass produced by growth
of organisms. Expressed as annual production. Production relative
to biomass is an expression of the turnover of organisms or
populations. Expressed in tons.
Most accurate measures rely on the concentration of chlorophyll a
(mg Chl a m-3 or m-2), as compared to organic carbon concentration
(measured via 14C labelling methods)
Explain how marine ecosystems can have greater biomass of consumers than producers.
As a result of tariffs, domestic producers tend to gain more than domestic consumers lose spend less money on lobbying have a greater incentive to lower their production costs lose more than the government gains
QUESTION 20 As a result of tariffs, domestic producers tend to gain more than domestic consumers lose spend less money on lobbying have a greater incentive to lower their production costs lose more than the government gains QUESTION 21
While many researchers have studied marine ecosystems from a single limiting nutrient perspective, evidence suggests resource colimitation is more common. This means that Choose one: A. the limiting nutrient is too energetically expensive to acquire B. competition for the limiting nutrient can make it less limiting. C. symbioses are required to maximize uptake of the limiting nutrient. D. there is more than one limiting nutrient.
Producers in the market for good X purchase advertising that helps to market it to consumers. Producers may profit from successful advertising but consumers cannot possibly benefit from it. Explain why or why not. Futures contracts can benefit both producers and consumers. How can this possibly be true when these are just legal documents that cannot possibly affect the quantity of the underlying commodity that is produced? Explain.
can a solution have a weight/ colume % greater than 100%? explain.
How does Producer Price Index effect producers of goods and therefore can have significant impacts to consumers?
A mature maple tree can have a mass of 1 ton or more (dry biomass, after removing the water), yet it starts from a seed that weighs less than 1 gram. Explain how this huge increase in mass occurs.
