Which world ecosystems are most productive in terms of biomass?

Answer 1

The correct answer is the ocean -- you know, the biome that we land-dwellers always forget. ;-) In fact, some biome lists omit the ocean biome entirely, which is really unfortunate. Ocean biomass does tend to be less dense than that of rainforests (per unit volume), but the original question seemed to be about size, not density. One could argue that it's unfair to consider all the oceans to be a single biome when terrestrial biomes are so finely subdivided, but everyone just refers to it as "the ocean biome", so there you go.

More speculatively, I recently saw a 2003 documentary which claims an even larger biome:

"With the discovery of microbes living in the vents perhaps miles below the sea floor, scientists began to consider that most of the biomass on earth might well live here beneath the volcanoes of the deep sea."

Mind you, they're not talking about the deep-sea hydrothermal vent communities that we're always hearing about. They're talking about the vast networks of underground fissures that *feed* these vents, extending deep into the Earth. So this is deeper than the deepest that we've ever explored. Anyway, I've no idea how accurate this documentary is; I can't find any corroborating sources.

Answer 2

a) The ecosystems that are productive in terms of biomass would be the ones that have an abundant resource supply. Some of these would be the tropical forest, coral reefs, and the bays and drowned valley where rivers meet the ocean would produce high biomass. b) The ecosystems that have the least production would involve the deserts which have a lack of water, the arctic tundra or high mountains which have very low temperatures would have low biomass. This would be because the lack of water limits the photosynthesis and the productivity slows down. Low temperatures lower the plant growth and the productivity. The open ocean has a lack of nutrients reducing the ability of algae to make use of the sunshine and the water. C) They use desert, tundra's, high mountains, grassland, scrublands, coniferous forest, temperate deciduous forest, intensive agricultures, tropical rainforest, estuaries, coral reefs, coastal zones, and open oceans.

Answer 3

Producers. There is a pyramid of ecology. Has producers ( Plants and trees), Primary consumers (Those animals who eat producers), Secondary consumers ( those animals which eat primary consumers) and territory consumers( predators).

Answer 4

In order for an ecosystem to produce a large amount of biomass, it must contain several plants and animals and have a warm, wet environment. A tropical rain forest has the most biomass.

Answer 5

the deserts of the world produce the least biomass, as the is the most limiting amount of water for organisms to survive

Answer 6

Plants may be one answer but in reality, insects have a much larger mass.

Answer 7

Most of the biomass in found in the first layer called the producers. These are plants and grasses.
