Food web
Food web is a representation of feeding relationships within a
community.
Trophic level
Trophic level is each feeding level within a food chain.
Energy pyramid
An energy pyramid represents how much energy each trophic level has
How does energy enter an ecosystem
As light energy
What do food chains begin with
A producer
What do food chains always end with
A decomposer
What does the pyramid of energy show
the amount of energy within a trophic level
Importance of ecological pyrmaids
Ecological pyramids are important as they allow scientists to assess the
impact of environmental factors on ecosystem health.
Population, ecosystem and community-rank in complexity
population, community, ecosystem
what form does energy convert to as it goes up the food pyramid
Metabolic heat
Interactions between populations and their environment allow
matter to be recycled and energy to flow through an ecosystem
ecological pyrmaids
Can provide a model that show the flow of energy and the recycling of matter through an ecosystem.
Pyramid of biomass
illustrates the total amount of living tissue within a given trophic level.
