Biodiversity, Ecosystem Stability, Abiotic Cycles_HB_JV

A cave region with one ecosystem, which supports small populations of many different species.

A grassland region with one ecosystem, which supports very large populations of a few different species.

A mountainous region with two ecosystems, each of which supports a few different species.

A coastal region with three ecosystems, each of which supports many different species.

In ecosystem A, the phytoplankton are the energy source for krill. In ecosystem B the phytoplankton is the food source for penguins.

In ecosystem A phytoplankton are the only producer, in ecosystem B phytoplankton are not the only producers.

In ecosystem A the absence of phytoplankton would result in the absence of all species, in ecosystem B the absence of phytoplankton would result in the absence of all species except the whale.

In ecosystem A the absence of phytoplankton would result in the absence of 6 species, in ecosystem B the absence of phytoplankton would result in the absence of all species.

If the voles were removed the gray wolves would eat coyote or elk instead.

If the wolves were removed the elk, coyote and vole would increase to too large of a population size that they would completely destroy all the grass grains and fruits and eventually decrease in population size themselves due to overgrazing. (Just like the rabbits did that were introduced to Australia)

If the wolves were removed the elk, coyote and vole would increase in population but not drastically.

If the voles were removed, the elk and coyote would keep the grass grains and fruits in check.

If the voles were removed the gray wolves would die.

If the voles were removed, the grasses, grains and fruits would grow out of control.

A sudden increase in the harvesting of corals, which decreases the coral population in the reef.

A decrease in the level of inbreeding in several seahorse populations in the reef.

The immigration of several new populations of sea urchins into the reef.

The overgrowth of a population of seaweed, which prevents light from reaching the reef.

The scientist's work may be flawed, and his work must be verified.

The chemical may be too expensive to manufacture for the general population.

Harmful problems for individuals and the environment may not be initially known.

The best use may not be immediately obvious, and the chemical may be wasted.

Organisms dependent on the flying fox would adapt to other organisms.

Plant populations would flourish due to lack of competition for resources.

The region would experience more extreme climatic conditions due to instability of plant and animal species.

Other animal and plant populations dependent on the flying fox would also decrease and may become extinct.

Production of fossil fuels will decrease as foliage is destroyed.

Soil erosion will decrease as ash covers and protects the topsoil.

Herbivore populations will increase as more plants become available for food.

Greenhouse gases will increase as carbon dioxide is not taken in by trees.

Only primary consumers would be affected

The ecosystem would collapse due to no energy input

Decomposers would take over the role of producers

Nothing would change

Secondary Consumers

Tertiary Consumers

carbon is dissolved in water to form a solution

carbon is stored in plants as glucose (complex carbon chains)

carbon compounds are absorbed by plant roots from soil

carbon compounds are broken down into simpler substances
