Trophic Levels EOC Review

to produce chemical energy for the ecosystem.

to provide radiant energy for producers to convert to chemical energy.

to start the energy flow of the ecosystem.

to provide mechanical energy for producers to convert to chemical energy.

The direction of population migration

Differences in dietary habits

Progressively smaller organisms

The direction of the energy flow

decomposers

consumers

producers

omnivores

3 and 4

all equal amounts of energy being transferred

2 and 3

1 and 2

plants

hawks and owls

spiders

foxes

It shows energy flowing from the top of the chain and downward.

The tropic levels are the opposite

It shows the amount of energy in each trophic level

It shows specific predator/prey relationships

energy decreases as you go up the food chain, just like the pyramid shape gets smaller as you go up.

energy increases up the food chain just like the pyramid shape gets smaller as you go up.

energy amounts are the same at each trophic level

They create all of the energy and therefore have the most energy of all of the trophic levels

There are more plants than animals.

They begin the flow of energy in an ecosystem.

All of these answers are correct.

True

False

It is destroyed after it is used up.

It is used for life processes or lost as body heat.

It remains for the next trophic level IF the predator consumes ALL of the organism.

It is lost completely as body heat.

More organisms die at higher levels than at lower levels, resulting in less mass at higher levels.

When organisms die at higher levels, their remains sink to lower levels, increasing the mass of lower levels.

Energy is lost to the environment at each level, so less mass can be supported at each higher level.

Organisms decay at each level, and thus less mass can be supported at higher levels
