First level consumer

Secong level producer

Third level consumer

Energy flows in one direction and nutrients recycle

Energy is limited in the biosphere and nutrients are always available

Nutrients flow in one direction and energy recycles

Energy forms chemical compounds and nutrients are lost as heat

Average temperature of the ecosystem

Type of soil in the ecosystem

Number and kinds of predators in the ecosystem

Concentration of oxygen in the ecosystem

Mutualism because the flower provides the insect with food, and the insect pollinates the flower

Parasitism because the insect lives off the nectar from the flower

Commensalism because the insect doesn’t harm the flower, and the flower doesn’t benefit from the relationship

Predation because the insect feeds on the flower

Primary succession is slow, and secondary succession is rapid

Secondary succession begins on soil, and primary succession begins on newly exposed surfaces

Primary succession modifies the environment, and secondary succession does not

Secondary succession begins with lichens, and primary succession begins with trees

The amount of available energy will increase because there will be fewer predators in the forest

The amount of available energy will increase because there will be less competition from producers.

The amount to available energy will decrease because fewer primary consumers will survive the lack of vegetation

The amount of energy will remain constant because secondary consumers are not reliant on primary consumers

The snakes introduced to the region dominated the habitat, forcing the mice to find another place to live

The mice became prey to the intoduced snakes, allowing the snake population to increase but decreasing the mice population.

The snakes introduced to the region competed with the mice for food, allowing the snake population to increase but decreasing the mice population.

The people in the surrounding area set traps that killed the mice, allowing the snakes to live without any predators and therefore to increase the number.

Death rate may rise

Birth rate may rise

Population will grow faster

Carrying capacity will change

Biological magnification of toxic compounds

Habitat fragmentation

Invasive species

Species preservation

It would increase a small amount since the insect population would decrease

It would remain about the same since the finches would change to a different habitat

It would increase exponentially since the insects would have limited places to hide

It would decrease considerably since the finches are specifically adapted to their niche

Polar bear and seal populations will both increase

Polar bear populations will decrease, and seal populations will increase

Polar bear populations will increase, and seal populations will decrease

Polar bear populations will decrease, and seal populations will remain the same

The salamanders will adapt to life on land

The salamanders will move to another river.

The salamanders will adapt to living in the muddy water

The salamanders will decrease in number because of the water quality

Because of density-independent factors

Unless the species require different abiotic factors

Because of the competitive exclusion principle

Unless the species require different biotic factors

Genetics

Anatomy

Forensics
