Essential Question How are organisms in the environment situated to provide energy to the different levels of food webs? Standard B.12C - analyze the flow of matter and energy through trophic levels using various models, including food chains, food webs, and ecological pyramids. PG 129

Energy flows through an ecosystem in one direction.

Energy flows from the sun to autotrophs and then to various heterotrophs.

The energy stored by producers can be passed through an ecosystem along a series of steps in which organisms transfer energy by eating and being eaten called a food chain.

Each step in a food chain or food web is called a trophic level.

Autotrophs always make up the first trophic level.

Heterotrophs always make up the second, third, or higher trophic levels.

In most ecosystems, feeding relationships are more complex than can be shown in a food chain.

When the feeding relationships among the various organisms in an ecosystem form a network of complex interactions, ecologists describe these relationships as a food web.

An ecological pyramid is diagram that shows the relative amounts of energy or matter contained in each trophic level of a food chain or food web.

Only about 10% of the energy available within one trophic level is transferred to organisms at the next trophic level.

The remaining energy is released into the environment as heat.

Using the 10% Rule, how much energy is at each level? Cal ? Cal Cal = a unit to measure energy …just like inches is a unit for measuring length!

How much energy is at each level? Cal 100 Cal 10 Cal 1 Cal 900 Cal as heat 9 Cal as heat 90 Cal as heat

The total amount of living tissue within a given trophic level is called biomass.

A biomass pyramid represents the amount of potential food available for each trophic level in an ecosystem.

Ecologists use a pyramid of numbers to represent the numbers of individuals at each trophic level.

The biological (living) influences on organisms within an ecosystem are called biotic factors.

Nonliving factors that shape an ecosystem are called abiotic factors.

Biotic = Living ABIOTIC = Non-Living

Together, biotic and abiotic factors determine the survival and growth of an organism and the productivity of the ecosystem in which the organism lives.
